Kids will adore our vast selection of simple science projects, which are all accessible to everybody.

Amazing Science Activities for Toddlers

My toddlers enjoy seeing 👀 magical experiments. I always advise and prefer doing such experiments 🔬 to strengthen their interest.

The following science activities for two to 3-year-olds will assist you in teaching science to even toddlers who have the ability and desire to do so!

Toddlers may discover the environment, learn via sensory play, see basic chemical reactions, and much more with the help of these entertaining scientific activities!

Try this “The Floor Is Lava” STEM challenge

Have you heard about The Floor Lava stem activity? 👎 No? Then do not worry; let me tell you about this in this section.

Although you may not want preschoolers crawling all over the furniture in the classroom to play “The Floor Is Lava,” they may do the same with their belongings in this adorable STEM activity!

Surround kids with an oversized bubble

Surround Kids With An Oversized Bubble

My kids always love soap bubbles 🫧, especially when they are big in size. I hope your kid will live this too if you provide them the soap, water, and some straws 😉 to do the bubble.

This exciting scientific project is sure to delight children. To make this happen, all you’ll need is a hard-shell baby pool, a little dish soap🧼, plus a hula hoop, but the rewards will be substantial.


A step stool is also advised if you’re doing this indoors to prevent children from getting bubble solution on them.

Watch rice dance in the water

You know that experiments with baking soda are always delightful to watch, and kids love this kind of activity 😄.

There are many interesting baking soda and vinegar experiments available, but this one is a perennial kid’s favorite. The rice dances🕺 and jumps around in the water as a result of the acid-base reaction, which is an amazing effect!

Reveal colors with chemical reactions

Reveal Colors With Chemical Reactions

I agree that revealing is always famous among kids and you should take this opportunity to enhance their science knowledge. 

Baking soda and vinegar are frequently used in preschool science experiments like this one. I recommend adding a small amount of food coloring to muffin pans and then sprinkling baking soda on top. 

Let kids 👦splash vinegar into the mixture to reveal gorgeous frothy hues, like I do.

Build a catapult

I would suggest encouraging your children to construct a catapult out of just three materials: plastic spoons, elastic bands, and Popsicle sticks. 

This can be difficult for children, so you’ll want to keep an additional set of grownup hands on hand. Bring a lot of peanuts or pom-poms to the launch, too, just like I do!

Discover strength in shapes

Learning various shapes always fascinates kids, and this can be a great opportunity for you to let your child be more interested in maths.

Learn shapes while applying some fundamental scientific principles. Ask children to guess which of several folded columns of paper will be able to hold the most books.

See what sinks and what floats

I will suggest you let your kids estimate which objects will dissolve in water while determining which ones won’t so that you may engage in additional water play. 

Have youngsters keep track of the outcomes so they can determine whether they have any similarities.

Build an aluminum foil boat

If you ask me, then I would say that kids can learn about physics and buoyancy while enjoying themselves. Give your kids 👦some tinfoil and ask them to construct a solid watercraft first. 

Then, ask them to try to fit as many pennies in the boat as they can without it sinking.

Watch hot water rise and cold water sink

Watch Hot Water Rise And Cold Water Sink

I always think that it is always fascinating to witness in motion an early investigation into the notion of density. My suggestion would be to encourage your children👦 to learn why hot water flows while cold water sinks. 

Ask your children 😊 to come up with a means to see air in action after you have explained that it functions similarly to air.

Grow a paper towel rainbow

Have you heard about the paper towel Rainbow activity? Let me tell you that Kids are always charmed by rainbow 🌈 and the vibrant colors. Even though the word “capillary action” could be difficult for young science students to keep in mind, they won’t need to in order to be amazed by this experiment. 

Markers, a paper towel, and two glasses of water are all you need.

Engage in some shadow science

Kids love going outside, and they are always amazed 😍 by their own shadows. As a parent, you have to let them know the science behind the shadow. 

Children will still love going outside to play with shadows despite the chilly weather. The youngsters will love doing a shadow puppet performance with these lovely animal puppets.

Mix up some “magic” milk

Mix Up Some “Magic” Milk

Milk always tastes good 👍, and the experiments with magic are also fantastic 👌.

The food coloring will dance and whirl across the top of a small container of milk🥛 when a few drops of dish soap are added.
