Family ( make it 2 articles ) 10 Fun and Easy STEM Projects You Can Do at Home with Kids

If you’re looking for a way to make learning fun (and keep the kids entertained), STEM projects are the perfect solution. They combine science, technology, engineering, and math in a hands-on way that kids love. The best part? You don’t need fancy supplies — most of these projects use items you already have at home. Here are 10 easy and exciting STEM activities that you can try with your little ones today!

1. DIY Volcano Eruption

Who doesn’t love a good explosion (the safe kind, of course)? Making a DIY volcano is a classic science experiment that never gets old. All you need is baking soda, vinegar, dish soap, and a plastic bottle. Set the bottle in the middle of a mound of dirt or play dough shaped like a volcano, add a few drops of food coloring, and watch the eruption!

Tip: Use a reusable baking soda and vinegar set to make clean-up easier and get everything you need in one go.

2. Build a Paper Bridge Challenge

This project is a great way to introduce engineering concepts to kids. Grab some paper, tape, and a stack of books. Challenge your kids to build a bridge that can hold a small toy or a few coins. It’s amazing to see how creative they can get with just a few simple materials.

Tip: Use construction paper for stronger, more durable bridges.

3. Make Homemade Slime

Slime is a hit with kids of all ages, and it’s a fantastic way to explore chemical reactions. You’ll need glue, baking soda, and contact lens solution. Mix them together, and watch the slime form right before your eyes! Add glitter or food coloring for a fun twist.

Tip: I recommend using Elmer’s Glue for the best slime consistency — it’s the secret ingredient for stretchy, non-sticky slime.

4. DIY Marble Run

Create your own marble run using cardboard tubes, tape, and a box. Let your kids design the track, then test it out with marbles or small balls. It’s a fun way to learn about gravity, speed, and problem-solving as they adjust their designs.

Tip: A set of colorful marbles can make this project even more exciting and add a bit of color to your creation.

5. Homemade Lava Lamp Experiment

This project is both mesmerizing and educational. Fill a glass jar halfway with oil, add water, and a few drops of food coloring. Drop in an effervescent tablet, and watch as colorful bubbles dance around like a real lava lamp. It’s a great way to teach kids about density and chemical reactions.

Tip: Use a clear glass jar set for the best visual effect — the clearer the jar, the better you can see the bubbles.

6. Build a Balloon Rocket

This activity is simple but so much fun. Thread a string through a straw and tape it between two chairs. Blow up a balloon (but don’t tie it), tape it to the straw, and let it go! The balloon will shoot across the room, showing the principles of propulsion and Newton’s Third Law.

Tip: Grab a set of long-lasting party balloons for multiple launches and experiments.

7. Create a Rainbow in a Jar

Teach your kids about density with this colorful experiment. Layer different liquids like honey, dish soap, water, and rubbing alcohol in a jar. Each liquid has a different density, so they won’t mix, creating a rainbow effect. It’s a beautiful and educational way to explore science.

Tip: Use food coloring drops to add vibrant colors and make the rainbow more striking.

8. Grow Crystals with Borax

This project is like magic — watching crystals grow right before your eyes! Dissolve Borax in hot water, add a pipe cleaner shaped like a star, and leave it overnight. By morning, you’ll have sparkling crystals that your kids will love.

Tip: A box of Borax detergent booster is all you need to create these stunning crystals.

9. Static Electricity Balloon Experiment

Explore static electricity with a simple balloon and a bit of hair-raising fun. Rub the balloon on your child’s hair or a wool sweater, then hold it close to small pieces of paper or cereal. Watch as the objects are attracted to the balloon — it’s a great way to teach kids about positive and negative charges.

Tip: Use eco-friendly balloons for a more sustainable choice.

10. Egg Drop Challenge

This classic STEM activity is all about creativity and problem-solving. Challenge your kids to create a contraption that will protect an egg from breaking when dropped from a height. Use materials like bubble wrap, straws, and tape. It’s a fantastic way to teach engineering and the scientific method.

Tip: A roll of strong masking tape is perfect for building and securing egg protection devices.

Final Thoughts

STEM projects don’t have to be complicated or expensive to be effective and fun. These easy activities are a great way to spark curiosity, teach new concepts, and spend quality time together as a family. So grab those household items, gather the kids, and get ready for some educational fun. You never know what amazing creations you’ll come up with next!

4. In a separate container, mix one cup of vinegar with a few drops of dish soap and food coloring.
5. Pour the vinegar mixture into the bottle and watch the eruption!

Educational Insight: This experiment demonstrates an acid-base reaction, producing carbon dioxide gas that causes the “lava” to overflow.

2. Homemade Slime

Materials Needed:
• White school glue (4 oz)
• Baking soda (1/2 teaspoon)
• Contact lens solution containing boric acid (1 tablespoon)
• Food coloring (optional)
• Mixing bowl and spoon

Instructions:

1. Pour the entire bottle of glue into the mixing bowl.
