50+ Science Experiments for 1-2 Year Olds (Toddlers)

Can you imagine! Teaching little babies’ science has become easy now.

Yes, with the help of science experiments.

I created this page to list down all Science Experiments for Toddlers (in the age group of 1-2). 
Science Activities for 1-2 year olds

I know that toddlers crave for attention and their mind is curious to explore everything they come across. Be assured, these are golden period for any kid as 80% of brain development happens below 3 years of growth. This is the right age to introduce science. 

Yes, I am not joking and I have done it with my two daughters. We have collected several experiments suitable for kids of age 1 and 2. Here in this article, you will find a brief intro for the experiment and the link where you can find the detailed steps to do the activity.

Spend a quality time with kids from their young age, as tender age is the right age for them to grasp things quickly.

We have crafted our toddler section having this in mind. Our activities help develop their motor skills and kindle curiosity about science. We strongly believe, some of these activities will be well suited to try at your home with your little buds.
