25+ Amazing and Fun STEM Activities for Kindergarten

Looking to add a little more STEM fun to your day? Check out these fun STEM activities for Kindergarten

STEM activities have gotten a lot of attention over the last few years. And for good reason!

Encouraging children to learn more about Science, Technology, Engineering, and Math can help to prepare them for the future. And Kindergarten is the perfect age to introduce these topics.

At this age, children are extra curious and eager to learn new things. They also love hands-on activities and projects that let them really explore a topic through all their senses.

Which is why I've put together this list of STEM activities for Kindergarten. You'll find activities that you can easily do at home that will introduce STEM topics in a fun and engaging way.

Let's dive in!

What are STEM Activities?

First things first, let's go over what a STEM activity is. STEM stands for Science, Technology, Engineering, and Mathematics.

STEM activities are designed to help your child develop skills and knowledge in these fields through hands-on learning experiences. They can come in the form of experiments, projects, challenges, games, and simulations.

Another perk of STEM activities is that they're a fun way to cover a variety of subjects. While the focus is on science, technology, engineering, and mathematics, you can also hit on other areas, such as language arts, social studies, and art.

Benefits of STEM Activities for Kindergarten

As I mentioned, STEM activities have become increasingly popular in education. They're a great way to help prepare students for the growing number of careers in STEM fields.

They also offer important logic and critical thinking skills that children don't get through worksheets and books. STEM activities help children practice problem-solving, planning, trial and error, creativity, and more.

Also, they're just plain fun! And as I'm you know, the more fun your kids have fun while learning, the more likely they are to remember and retain the information.

Supplies Needed for STEM Activities for Kindergarten

The last thing I want to go over before we get into the list of STEM activities for Kindergarten are supplies that you'll want to have on hand. The activities listed are all fairly simple and won't require a crazy list of complex ingredients. (Because, really, who has time for that??)

But there are some things you'll want to make sure you have on hand:

  • Construction paper
  • Tape
  • Scissors
  • Glue
  • Toothpicks
  • LEGOs
  • Food coloring
  • Plastic cups
  • Straws
  • Markers

You might need one or two extra supplies for specific activities, but if you generally keep a supply of these on hand, you'll be good to go.

STEM Activities for Kindergarten

Alright, time to dive into this list of STEM activities for Kindergarten.

Below I've included a brief description of the activity so you can get a quick idea of what it is. If you want to see the full instructions, just click the link in the title.

And just so you know, these activities are geared toward kindergarteners, but most of them can be done with kids younger and older. I did quite a few activities with all 3 of my kids (ages 12, 9, and 5) and they had a blast!

1.) Paper Structure Building Challenge

Our first STEM activity is a Paper Structure Building Challenge from Hands On Teaching Ideas. To do this one all you'll need is a collection of paper plates and empty toilet paper or paper towel rolls.

See who can build the tallest tower for a small toy. The tallest tower built in a set amount of time wins!

2.) Roller Coaster Challenge

Another fun STEM activity for kindergarteners is this Roller Coaster Challenge, also from Hands On Teaching Ideas. All you'll need is some construction paper, glue/tape, scissors, and some markers.

This one can be done in teams or as an individual challenge. See who can build the best roller coaster for their car!

3.) Apple Boat Experiment

If you have some apples lying around, this Apple Boat Experiment from Hands On Teaching Ideas is another fun one to try. All you need are some apples, toothpicks, and a large bowl full of water.

Then you can experiment with making different types of boats with the apples and toothpicks. As a bonus, see if your kids can make a boat that a little toy figure could sail on.

4.) Snow Home Challenge

This Snow Home Challenge from Hands On Teaching Ideas is a fun STEM activity you can do during the winter. Using mini marshmallows and toothpicks see who can build the best winter home.

The activity suggests making one for a polar bear, but I think you could use any winter animal or even a person and build an igloo.

5.) 100 Cup Tower Challenge

If you're looking for a STEM activity that requires zero prep, definitely try this 100 Cup Tower Challenge from Little Bins Little Hands. All you need are a bunch of plastic cups and you're good to go.

See who can build the tallest tower out of cups in a certain amount of time.

6.) Nest Building

I tried out this Nest Building STEM activity from Kids Craft Room with all 3 of my kids and they loved it! If you're looking to get some time outside, have the kids round up a bunch of sticks, leaves, etc, and see who can build the best bird nest.

Or if the weather isn't cooperating, you could also bring the supplies inside and have them build their nest on a paper plate.

7.) Marshmallow Snowman

Next on our list of STEM activities for Kindergarten is the Marshmallow Snowman challenge from Mombrite. All you need are some marshmallows (regular and mini), some toothpicks, and some markers.

Then have your kids see who can build the tallest marshmallow snowman. This activity looks fun and delicious! 😋

8.) Build a Functioning Heart Model

Next on our list of STEM activities for Kindergarten is this functioning heart model from STEAM Powered Family. With just some plastic bottles, straws, and some playdough, you can build a hands-on demonstration of how the heart works.

This activity could easily lead off into lots of discussions of the human body, circulation, and other science topics.

9.) Build a Lego Bridge

This next activity is another one I've done with my kids that was a total hit. Take a piece of blue construction paper to make a river and then challenge your kids to build a bridge across it.

You could have them see who can build the longest bridge, who can build the strongest bridge, what's the smallest amount of LEGOs you can use, etc. The options are pretty endless with this activity.

10.) Sorting and Graphing

A fun STEM activity to help build those early math skills is this sorting and graphing activity from Frugal Fun for Boys and Girls. All you need is a posterboard and a group of toys. (You could use animals, cars, blocks, etc.)

You can have your kids sort them by color, size, shape, or whatever you come up with. Then have them graph the animals on the poster board.

From there you can count them, see which group has more, and so on. After that, you can sort them another way, or try another group of toys.

11.) Valentine's Sorting Activity

If you need an activity for February, definitely try out this Valentine's Sorting Activity from The Kindergarten Connection. You'll need to do a little prep ahead of time to create the mailboxes and valentines.

But if you laminate them as the instructions suggest, you can reuse them over and over again.

Something else that's great about this activity is that you can use it to practice whatever skill you're working on. You can do numbers, letters, words, shapes, etc.

12.) 5 Minute Fizzy Fun Jar

This 5 Minute Fizzy Fun Jar from A Mothership Down looks so fun and is next on my list of activities to do with my own kids. All you need is a small jar, food coloring, clear carbonated soda, and some salt.

Then sit back and watch the fizzy action! To dive a little deeper into this activity, you can talk to your kids about what they think will happen when they combine the ingredients.

Or maybe even see if you get a reaction from mixing in other types of ingredients.

13.) Walking Water

Another really fun STEM activity for Kindergarten is this Walking Water activity from Your Local Families Magazine. All you need to do this one is some paper towels, cups, food coloring, and water.

Then sit back and watch the magic happen. This activity can take a few hours, so it's a good one to check back in on throughout the day.

If you do it with older kids, you could also have them keep notes and write down their observations every 30 minutes or so.

14.) DIY Invisible Ink

Another great experiment is writing with the DIY Invisible Ink from Team Cartwright. To do this activity, all you need is a few lemons, q-tips, paper, and an oven.
