Make a Christmas tree bubble wand and explore bubble science through play

Playing bubble is my pass time activity with kids. We used to have loads of joy. I wanted to gift my kids with happiness this Christmas with a DIY bubble wand. This will double the joy of Christmas fun and wands matching the occasion!

We have made wands several times for different occasion and trust me there is a learning every time. The physics concepts are learned from this experiment. We try different shape and make it unique every time.

All age group kids will enjoy with bubbles and at each age, they will experience different fun. Usually, babies will be fond of seeing and touching bubbles. On the other hand preschooler and KG kids will learn how to make it and how it works. My daughter’s Pritika and Tisha were 6 and 4 respectively when we tried this for Christmas.

How to make a Christmas Tree Bubble Wand

Things required

  • green tape
  • chopsticks
  • bubble mix solution
  • a cup
  • 12″ x 6mm pipe cleaner sparkly metallic green and 12″ x 6mm pipe cleaner furry green

From the list, you can see that there are two pipe cleaners we used namely the sparkly and the furry type. The trees will look different. Both displayed the same performance but my kids enjoyed sparkly one when compared to the furry type.

 Instructions to make them

  1. Take the pipe cleaner and fold it into half and mark the center point which will be the top of the Christmas tree.
  2. Bend and make a Christmas tree shape by joining the end in the center of the tree base
  3. Twist the rest of the pipe cleaner around chopstick end.
  4. Use tape to wrap it and secure it.
  5. Take the bubble mix in a bowl
  6. Before blowing check with kids if they know what shape will come out of the wands.
  7. Dip the bubble wand in the mix and blow

Tisha expected it to come out in Christmas tree shape. But she understood that it will be only round in shape after blowing a couple of times.

Then I explained to her about the science behind it in simple words.

I told her that the shape is a sphere and it is happening due to the push-pull force between air and the bubble mixture.

Blowing bubbles with a DIY Christmas tree bubble wand

Christmas tree bubble wands

Later on, my elder one joined us from school and then I gave her a detailed explanation.

I told her that air is present everywhere but not visible and it can be felt. The soap solution reduces the surface tension of the water. When the bubble is floating the air present inside push the bubble outside and air outside pushes the bubble in and hence there is a push-pull force which makes the shape round.

Even with the Christmas tree shaped bubble wand the bubble will be round as the sharp corners will not balance out the inside and outside air. The outside air will push persistently till bubbles become round. Pritika observed that when the bubble landed on a slippery table it change shape to semi-sphere.

Semi sphere bubble

I told her that the third force coming from the table makes it appear flat on the table Hence, spherical bubble lands as a semi-spherical one. Pritika tried adding another bubble to the first one to see the shape.

Every time the touching portion appeared to be flat. Rest of the portion was round in shape.

Then we imagined and tried to make many bubbles float around attaching to each other. The bubble in the center will become a cube as all other bubbles touching it will make it flat. Across all sides, the sphere becomes flat to appear like a cube.

She also tried to look at the biggest bubble and its structure. She did eight bubbles on the table. It took time to stack and few disappeared in the process and she managed to arrange 8 of them in one go.

Creating a seven or eight bubble structure

Likewise, she tried in different ways and we enjoyed. Tisha had more fun and less understanding. But Pritika understood concepts and experimented new things. 

Fun Science

Bubble mix contains soap and water. Adding soap to the water lessens the surface tension and hence water becomes thin and flexible. So you can make great bubbles with this texture.

Therefore bubbles are made up of the soapy water film containing air inside. The pushing out force of the air inside the bubble and the pushing in force of the air outside will balance out by forming a round shape.

Do you want to know the shape of the bubble in space?

Catapult STEM Project – DIY Catapult for Kids

We are going to add fun to your kid’s life with a catapult experiment. Do not throw the Popsicle stick next time when you buy an ice candy. It will be useful for our STEM project which includes math, engineering, physics, and play as well.

How many of you agree to my point that ‘Exploring physics is bit boring for kids’!? I guess most of them say ‘Yes’. But this time I have come up with a special activity that proves physics and STEM could be so much fun. That is nothing but ‘Making a Catapult at home’.

lets build catapult for kids

Catapult!! Have you wondered listening the word ‘Catapult’!? I would say, ‘Yes we can make catapult at home with our kids absolutely’. Building a catapult with our kids would starts out as a craft and ends with an energetic fun activity. The end result could be the wonderful and perfect toy for kids.

What is a Catapult?

A catapult is an ancient weapon or a ballistic device used mainly to launch stones, spears, and projectiles to a greater distance without the help of explosives. It is in use since ancient times and proven to be one of the most effective mechanisms in military during war.

Making a Catapult is a classic building activity and fun science project for kids during summer. This activity doesn’t need you to run behind the fancy stores since it requires only few commonly used household things (kids are familiar with).

Today, we made three different mini catapults in three different methods. I have included a video too along with the post i.e. on the catapult action-how it works after it is made. I know you all are also eagerly waiting to learn. Ok! Let us learn how to make a catapult at home.

Suitable For

No hard and fast rule as to who must try this activity. It is best suited for all the naughty little toddlers, girls and boys from age 3 and above. My little ones are 3+ and 5+ and both had equal fun.

Off course the preschoolers need some guidance and support, to begin with, the projectiles as well as to measure the distance. Instruct them to make a mark with chalk on the floor every time the projectile reaches to know the longest distance the catapult travels. Explain to them why the distance varies every time even though it is the same catapult and same kid does it.

However, 5+ years kids will be eager to measure the distance on their own. You can even teach them to make a table and draw a graph with many readings. Don’t spoon-feed them but ask them to find a way to measure the distance. You will be surprised to see the brainpower of your kids.

On the other hand, ask 7+ kids to design a catapult on their own. They will start from scratch. Let them find out by making the arms short and long to see how they work and the projectile distance.  They will understand the force and the foolproof length of the arm etc by doing on their own.

Method 1 : Making a Catapult at home using Popsicle sticks

Items needed to build a catapult

Building a mini catapult with Popsicle sticks require very few items or supplies. Let us see.

[*Product links are affiliate links. Your support is highly appreciated]

Procedure

Step-1: Create the base of the catapult

Stack two Popsicle sticks and glue it together in order to make it standard. Make a square shaped base using these stacked popsicles. Use rubber bands to make ‘U’ shape and tie them near corners to create a square shaped base. On the fourth side, use a cylindrical shaped thin wooden stick and tie it to the corners of the ‘U’ shaped base so that it is making a square shaped base all together. Do not forget to pass a 2 inch straw piece in the middle of the wooden stick.

Step-2: Create a t-shape

As the title suggests, create a ‘T’ shape at the fourth side where we have attached a piece of straw. This time you need to use glue to fix it to the Popsicle stick since it need to be strong to hold little weight.

 Step-3: Attach Bottle cap

Now, it’s time to arrange some space for the projectiles (nothing but our tiny objects like marsh mallows or cotton balls or any light weighted plastic balls) to launch. Attach a bottle cap upside down to the free end of the ‘T’ shaped Popsicle (on top side). The bottle cap is used to launch tiny objects as projectiles for our activity. 🙂

Step-4: Attach a spring

A spring of about an inch should be attached to the Popsicle stick which is quiet opposite side of the wooden stick where the straw is inserted. Glue it to the Popsicle so that it does not move or shake during experiment. After attaching the spring make sure the spring is quiet in the middle of the Popsicle and quiet down to the bottle cap end as shown in the figure.

attach spring to catapult base

Here we go, our powerful mini catapult is ready to launch projectiles for our simple and engineering project for our little ones. My kids had a blast after preparing this in front of their eyes. All it needs is a little patience and time for your kids to show them such a beautiful and educational act.

Method 2 : Using the Same Base

Now we are going to learn second method using the same base. This time my elder daughter created the base in my direction. I am happy kids showing interest towards STEM activities. J

Step-1 Create a base

Create a square shaped base using Popsicle sticks, rubber bands, wooden stick, a piece of straw and glue. You can go through the step 1 of first method and follow the same.

Step-2: Attach Vertical Supporting Structures

Do not get confused!! Look at the picture and you will get an idea. Just attach to Popsicle sticks vertically to end of the base means you are attaching two Popsicle sticks each at one side. No need to add on all sides. Just attach to the adjacent sides of the wooden stick.

build big catapult structure

As shown in the figure bring the two free ends of the vertically placed Popsicle sticks to the middle point and tie them with a rubber band. Repeat the same to the other opposite side also. Now the Popsicle sticks give triangle shape (when we look from the sides) and looks like supporting or side walls to the base.

Step-3: Place a Popsicle stick on the top

Now as we called it as supporting walls, place a Popsicle stick horizontally attaching both the vertical shaped structures on the sides. Always see the figures we uploaded not to get mislead. Take the support of the ‘V’ shaped groove formed while making the vertical shaped assemblies. Now the whole structure gives the shape of a swing (outline shape) which we see in the kids play area.

Step-4 Attach the basket to launch projectiles

Arrange the basket for our tiny projectiles to launch again using Popsicle stick. At one free end attach a piece of straw in order to extend the length according to our catapult skeleton. (If it is not required for you then you can directly attach the bottle cap to the Popsicle stick. This is an optional step).

attach rubber band for rotating motion

Step-5: Glue the basket to the Catapult skeleton

Now attach the already made basket arrangement (shooting arm) to the straw using a glue. Glue fixes the shooting arm strongly so that it could bear enough tension. Use rubber bands and twist along the shooting arm and the horizontal Popsicle stick to give enough tension to the shooting arm.

Load some small and light weighed objects to the ammunition basket and that’s it. Your mini catapult is ready to fire.

Method 3 : Plastic Spoons and Popsicle sticks

Supplies required

[*Product links are affiliate links. Your support is highly appreciated]

Step-1: Create a base

As we do in above two methods, the first step is to create base but this time it is different base. Let us see what it is!

You can follow the step by step instructions given in the Instructables as I did as they are clear and visual.

Take 5 Popsicle sticks and stack them together on top of each other. Be sure to stack them neatly. You can use the tighter rubber band to secure them tightly and not to move.

Step-2: Create an arm

Take another two Popsicle sticks and stack them on top of each other (as we did in the first step). Secure them at one end with the help of rubber band. So simple!! You are done with creating arm. Are you thinking how!? Don’t scratch your head. J Here the simple trick is just bend the other free end towards you (means outwards) thus creating an arm.

making and testing catapults

Step-3: Attach the base to the arm

Take the arm base and pull one of the free end of the stacked Popsicle base towards you resulting in a ‘V’ shape format. Now place the main base (made of 5 stacked Popsicles) in between the ‘V’ shape of the arm. Make sure you place the main base one half inch away from the end that is tied with rubber band.

Wrap a rubber band around the arm and the base in order to secure the arm to the base.

Step-4: Glue the Bottle Cap

Now create a basket for the ammunition to launch. Glue a bottle cap to the free end of the arm of the mini catapult that serves as a basket for projectiles (marsh mallows, ping poms, cotton balls) to launch.

Your catapult is ready to launch your tiny projectiles. J As I said it is very easy to assemble catapult using Popsicle sticks and rubber bands. Am I right!? Hope you all agree. J You can try using simple plastic spoons attaching to the free end of the Popsicle stick and make use it as an ammunition basket. Use rubber bands to fix the spoons to the Popsicle stick.

Catapult science, engineering and maths (STEM) activity for kids

 

Measuring distance - Catapult STEM activity for kids, that combines science, engineering and maths with play

 

Observations

Don’t panic to look at this picture, trust me it is easy once you get a hold of the design. Kids can do it themselves. So have the patience for the first time.

1) Try changing the different angles of the rubber bands

2) Add additional tighter rubber bands and observe whether it is making any difference in catapult’s power.

3) Launch different objects in the ammunition basket like ping pong balls, pom poms, and marsh mallows etc. and observe which one is going farthest!

Test #1: Which is powerful and travels a long distance

My younger one Tisha was so excited to do it. With a line marked on the floor as the beginning line, we began with our experiment. Every time she used the catapult and started making lines on the floor to measure the distance. She did a great job using a tape. With my help, she also noted the readings down.

My elder one Pritika did it herself and measured too. Both of them tried thrice on all catapults and compared the measurements.

Test#2: Now to measure the height

We now started talking about measuring the height as we thoroughly understood and equally had fun with the length. Here we even shared views about the design and the trajectory. 

Now we did it with a Magna Tile tower to monitor the square in which the projectile hits and that was easy to measure the height as well.

It all began with a 6 square high tower. Yes, we did it and the projectile reached the top. Again we made some changes to the tower height and adjusted the start line position as well.

We tried a couple of times to conclude on some details by using all the 3 catapults. Finally, we understood that we require a tall tower.

Fun Science Facts behind Catapult

Using a catapult now launching a projectile is quick and easy and there are no explosives required.

The science behind it explains kids to learn how the energy is created, stored, transferred and converted. Basically, a catapult works on energy transfer from one object to another object. We are talking about the energy much but where is this energy stored!? The energy is added and stored in the Popsicle stick when the tiny projectiles are added to the basket (bottle cap).

When you let go the Popsicle stick, the stored energy is transferred to the object launched in the bottle cap which then flies through the air. Catapult also uses the elastic energy which is transformed into the kinetic energy under tension stored in the rubber bands. Here we need to remember one physics formula we studied in our school. I.e. the amount of force is directly related to the amount of the mass. If the mass of the projectile is increased, then it requires more force to convert the stored energy into kinetic energy. The extra force is created by using more elastic bands. The transferred kinetic energy is the main reason for throwing the projectile out of the bottle cap.

 

These devices are in use for several years as well they come in any size and shape. There are simple slingshot types and complicated trebuchet types are available. These are large one which will let launching of large boulders and knocking down even a castle wall is easy.

 

The path taken by the projectile is called the trajectory. The material flies in the air and the force applied to the catapult influences this distance. The release angle, projectile weight, resistance of air as well as gravity can be learned in this experiment.

You can make your own catapult and it is the best STEM activities which you should not miss ever. Loads of fun and science in it.

We did not stop just with making the experiment but explained about the need for STEM to little girls. We always want to make out little princess a scientist.

Now, coming to the catapult, we already made an upcycled catapult and enjoyed deeply. This time we are making a catapult with a twist and used ice candy sticks. Do you know what, I have a fascination for this since my childhood? Made this dream come true with my two angles.

It’s time to try yourself to find the catapult projectile distance, trajectory height, and consistency as well. You can try with different objects and apply different force to test in a different manner.

Some Questions for Discussion

What is the science behind rubber band catapult?
The catapult science basically involves some physics and engineering skills to hurl a projectile without the use of an explosive. It works mainly by using potential and kinetic energy stored in the rubber bands. Potential energy is the store energy where as the kinetic energy is the energy in motion. Also, the three primary energy storage mechanisms that help the catapult to work are torsion, tension and gravity. A catapult store energy every time you stretch the rubber band and until you hit the trigger. When you let go off this rubber band, the potential energy is released creating a force. The force of this energy is responsible for the flung of any object (upwards or forwards) attached to the rubber band. 
How does a catapult get its energy?
A catapult gets energy either from the twisted ropes or the rubber bands. When you stretch a rubber band the potential energy stored is converted into kinetic energy. These are the two main energies used for the catapult’s action. 
How high can a catapult shoot?

In medieval period, the largest trebuchets (with throwing arms 50 feet in length and ~20,000 lbs counterweight) could throw stones 200-300 lbs to a distance of about 1000 feet. While the modern torsion catapults can fire 400 m to 500 m and any that can’t shoot 300 m [ i.e.. bow range] are useless. To achieve maximum accuracy and effect rocks must be spherical. 
Who invented catapult?
Catapults were invented by the ancient Greeks. The Greek Dionysius (the Elder of Syracuse), who was looking to develop a new type of weapon, invented the catapult about 400 BCE. Thereafter, it became a key weapon in warfare and remained so up through medieval times. In ancient India, they were used by the Magadhan Emperor Ajatshatru around (the early to mid) 5th century BC.
How does a catapult relate to physics?
A catapult actually works on the three main terms of physics i.e. tension, torsion and gravity. Also it works on energy storage mechanisms (nothing but the stored potential energy and energy in motion kinetic energy) says that a catapult works on physics. Newton’s second law relates an acceleration, object’s mass, and force with which it is moving. We can also observe this law when the projectile hits the ground. All these moments reminds us physics. 
What are the 3 type sof catapults?
The three main types of catapults are:
1) Ballista: The ballista is a missile weapon, very similar to a cross bow that launches a large projectile at a distant target.
2) Mangonel: The mangonel is the most iconic catapult which comes the first in our mind when we think of catapults. It is basically made of wooden arms and a bucket to launch projectiles. 
3) Trebuchet: The trebuchet is bit different in model when compared to the above two catapults. It is made with a long arm (balanced on a fulcrum) and short arm (to counter balance). The Trebuchet was designed for max power and distance.

What kind of energy is used in a catapult?
When you use your catapult to launch a cube you are transforming Potential into Kinetic Energy. Potential Energy is the stored energy and  the kinetic energy is the energy of motion. When you twist the rubber band, tension is created and stored in the twisted band. When you let go the rubber band the released kinetic energy helps to throw off the launched projectile.
What came first the catapult or trebuchet?
Catapults are invented first during ancient times. Though they are good at accuracy, trebuchets are invented by chinese to attain greater range of accuracy and maximum force and power. The main difference between both are trebuchet uses a swinging arm to throw a projectile. Without such a sling (swinging arm), the machine would be a catapult.
Why is a trebuchet better than a catapult?
Trebuchet are most powerful catapults, specially designed for maximum force and power. Trebuchets are believed to be invented by the chinese in 300 BC. The trebuchet was preferred over a catapult due to its greater accuracy and greater range capability. A trebuchet works by using the energy of a falling (and hinged) counterweight to launch a projectile, using mechanical advantage to achieve a high launch speed.

How To Make Balance Scales for Toddlers and Preschoolers

Lets make balancing scale

Toddlers and preschoolers always love to weigh every item. They play “Which one is heavier?” game and we can now help them make a balance scale at home. Side by side you can also teach them about gravity.

Lets make balancing scale

My elder daughter is 7 years old now and she started learning about measurement and weights in Maths. So I had to make a homemade balance scale. Firstly, I thought it would be very difficult to make a balance scale but once I started working on it I realized that it is much easier than I thought.

Our balance scale is a simple balance, a rod with a pan at each end that is suspended in the middle. This is a perfect activity for introducing the kids to the concepts of weight and measurement. So let us add little balance to our day-to day life.

Suitable For
Children who are 5 years and older are perfect to do this experiment. However, both toddlers and preschoolers can also try this. Tisha had real fun and she is 3.5 years old when we did the simpler version of this experiment (scroll down to the second part)!

What Your Child Will Learn or Practice

  • How to compare and contrast objects
  • Estimation skills
  • Measurement skills
  • Force of gravity

Materials required

What We Need

  • Two identical paper plates
  • Scissors
  • Measuring tape
  • Pencils to mark
  • Thread
  • A long and big straw
  • Jump clips
  • Paper clips
  • A long stick (should be of same length like straw)

Building a Balancing Scale

Balance scales are often used to find weight. Balance scales work like a seesaw. They have two main parts: the beam and the fulcrum.

1) Making Baskets for the scale: To make a homemade balance scale at home, we require two identical paper plates. Punch three holes to each plate using a hole punch. Make sure to make the holes close to the rim of the paper plates and in a triangular shape. If you don’t have paper plates, you can make use of plastic or paper cups to serve the purpose.

2) Making the strings: Take six pieces of woollen thread that are each around two feet long and cut. You can use any kind of strings which perfectly balances the balance scale. Thick and strong strings make the balance scale more durable. After you cut the strings, please check whether all the strings are of same length or not. If not adjust them by cutting using scissors.
Making Balance Scale plate

3) Attaching the strings to the plates: Insert the three strings to one of the paper plate separately in to the three holes made. Repeat the same to the other paper plate as well. Then bring the free ends of the strings together to the centre point and give a knot. Insert a paper pin around the knot as if to hold the paper plate perfectly. You can follow our pictures to get an idea on how to insert and tie up the strings.

4) Making a beam: Beam holds the objects to be weighed in the weighing baskets. In order to make beam, measure the length of the long straw and cut according to our required length. It depends on how big we are going to make the balance scale.

5) Attach the weighing baskets to the beam: Now beam is ready in your hands. Insert two jump clips one each at the free end of the straw as shown in the figure. These jump clips help to hold the weighing baskets freely on both sides of the beam. Now the model looks like a see-saw. J Take a piece of woollen string and tie it to the beam exactly in the middle. This helps to hold the beam to the fulcrum.

My younger kid Tisha started shouting and clapping seeing the see saw like model thinking that I am going to make one of her play area rides. J Sometimes kids are too innocent to understand the things that are happening around. No matter what she understands but younger kids enjoy watching this activity.

6) Making fulcrum: Fulcrum is also one of the major parts of a simple balance. It helps to hold the beam up and move. Take the wooden stick and a pencil and tie up both together. Now bring the stick and pencil perpendicular to each other. See the figures for reference. Now attach beam and the fulcrum with the help of the small woollen string (in the middle of the beam). But where!? The answer is you can attach to one free end of the pencil. Almost we are nearing to end the activity.

7) Wrapping up: Now that your balance scale is almost ready. I made a thick and hard base using hard thermocol sheet. Tisha was excited to paint thermocol and she used black color to paint. We made a hole exactly in the centre of the thermocol base so that we can insert our simple balance scale in the hole.

Now we are ready with the homemade balance scale to measure and weigh the objects. It is easy to weigh any objects using balance scale. Place the objects that you wish to weigh on one side of the weighing balance machine. Add standard weights to the other pan. Check the weight of the objects being placed according to the standard weights.

Here is our little homemade balance scale. My elder daughter proudly displayed it to all her friends in our society and explained how the balance scale works to measure weights. My kids enjoyed weighing the small objects like paper pins, dice etc…Every day they are using balance scale measuring whatever the objects they find in the home. 🙂 As a parent I am very happy to see kids learning some simple craft science experiments even at home. I highly recommend you to try out this simple experiment along with your kids and do amaze everyone around you with your discoveries and research. 

Building a Simple Balance Scale Using Coat Hanger

I wanted to make a simpler version of the balance scale to teach my younger one. Here is another version of balance scale that you can try at home. 

Which one is heavier fun science for toddlers

This 10 minutes craft is fun and can be made by kids very easily. Tisha my 2.11-year-old little one enjoyed making this and went crazy at the end of the day. It was so exciting and she was looking for objects at home to weigh them. Did not spare any single toy from weighing.

She compared weights of the following things.

  • Tangerine
  • Christmas baubles
  • Costume jewels
  • Lego Duplo animals
  • Mandarins
  • Decorative pebbles

Collecting items to weigh

She will collect things in the bucket and run to the balance scale and weight them. We composed a song in a rhythm and shouted “Which is heavier?” while comparing the buckets and she will point to the bucket that is heavier correctly. I will ask her how. Then she will explain to me that the bucket with more weight will go down when compared to the other.

 

I was happy for my Tisha as for her age she understood gravity very clearly.

Which one is heavier weight game for toddlers

Things required to make DIY Balance Scales 

  • paper cups – 2
  • children’s clothes hanger and notches
  • kitchen twine
  • scissors
  • single hole punch

Links (*Affiliate) are added so that you can purchase things in case they are not available at home. However, I had all at home.

How to make a DIY balance scale using coat hanger

  1. Take one coat hanger and hang it in a place where it can swing. But make sure it is not tied at a height. Let it be accessible to kids. I did it on my pantry door.
  2. Using a hole punch create holes in the paper cup to tie twines of equal length and make it look like a bucket.

Let it be lengthier so that kids can handle them easily. Also, they can remove and hang them on their own.

Kids can add items to the scale all by themselves

3. Instruct kids to fill the bucket with things.

Let them feel free to do it and anything can be filled. As long as it is solid in nature to avoid any mess. Let the kids guess which will be heavier before they see the results.

 4. Now by adding the buckets with the hanger, your kids can witness the heaviest bucket by noticing that heavier one moves down.

Toddler science comparing the weight of Duplo animals vs Christmas decorations

If they have guessed it correctly, then ask them how? Also, teach them about gravity. Allow them to change things and understand better about weight and balancing.

Slowly they will get a hold. Show them about balancing with equal weights in both buckets as well.

Do not keep on tracking them but let them explore and ask them to make a note of their observation. But let them guess every time to make sure they understand the weights correctly.

Tisha was explaining her dad with so much excitement and demonstrated everything to her.

This kept them busy in their “Which one is heavier?” game for couple of hours 🙂

Fun Science Fact
Gravity is nothing but a force which pulls things downwards. The earth core in the center attracts things towards itself and heavier things move lower than the others. Therefore gravity pulls the object downwards.
