What are some easy science projects for toddlers?

Science projects don’t need to be hard or complicated. We start exploring science concepts when our kids are little and we don’t even realize it!

Have you ever had a baby that drops their pacifier or food off a high chair?

Early on babies and toddlers begin exploring gravity and force as they drop and throw things. They also discover what can sink or float as they play in the bathtub.

Parents can use everyday experiences to teach science concepts.

There are also so many amazing toddler science experiments that aren’t difficult. 

You are going to love these 25+ science projects that are perfect for toddlers (and even preschoolers)!

Baking Soda & Vinegar Science Activities

If you want to get kids excited about science, start with baking soda and vinegar. You can make these two items the staple of your science activity materials stash. Baking soda and vinegar react together to make a fun fizzy mess. 

I have done baking soda & vinegar science activities with hundreds of kids. Trust me, they will love them.

Pro tip: Make sure you buy baking soda and vinegar in bulk.

Bubble Science Activities

Bubbles are a magical thing for toddlers. They are shiny and sparkly… and float. What’s not to love? 

In addition to being a cool science activity, playing with bubbles can be a calming sensory activity too. You can either make bubbles to play with and blow or create foam and explore it with your hands. Both are so cool!

To make bubbles you typically need water and Dawn dish soap or Bubblebath. Click on the tutorials below for specific instructions.
