Easy Science Experiments for Kids

My kids LOVE doing little science experiments. They could do them all afternoon…ok who am I kidding? I am the one who loves doing them and have brainwashed my children along the way.   I remember doing a few as a kid with basic kitchen ingredients that we always had. It was so fun showing my kids the same experiments and watching their faces light up!  We’ve learned some new ones over the years and thought it would be fun to share some of our favorites. {I would LOVE LOVE LOVE to hear some that you have done. Leave me a comment and we will try them too!}

Freaked Out Pepper
This is the one I did all the time when I was little. Who doesn’t have dish soap and pepper on hand at all times? It’s a quick and easy little experiment for the kids.

Pour some water into a shallow bowl.
Sprinkle ground pepper over the water.
Pour a small drop of dish soap on your index finger and dip your finger into the center of the dish of water.
The pepper freaks out and runs to the side!
Bobbing Raisins
Put a few raising in a jar/glass.
Add some soda. 7-up and clear sodas work great, but we only had an orange Fanta. It worked too, but wasn’t quite as easy to see all of the raisins.
The raisins become surrounded by the carbonated bubbles and start bobbing to the surface and then fall. It is fun to watch! We even made a little video showing the raising bobbing up and down. Pardon the silly voices and whining in the background!
Rocket Balloon
This little rocket balloon was super quick to make. You will need a straw (about 5″), balloon and a long length of string.

String up your straw. Sometimes adding a little piece of tape on the end of the string helps thread the straw easier.

Hold an inflated balloon against the straw (do not tie off balloon, just hold it)

Tape the straw to the balloon with a piece of tape.
Now watch what happens…
 We all started giggling when the balloon started making the farting sound. The longer the string and bigger the balloon, the father the balloon will go.
Fizzing Colors

Baking soda and vinegar is nothing new, but Kaylee came up to me the other day and said, “Can I do an experiment by myself?” The first thing I thought of was mixing some colors with vinegar and baking soda. It’s easy, quick and simple for little ones to do.

She added a drop of food coloring into each cup and a small scoop of baking soda.

Then she added a tablespoon of vinegar and watched the reaction.

“This is SO cool!” She loved it and kept adding small amounts of vinegar and baking soda to keep the reaction going over and over and over.

Creating Colors

Kaylee had so much fun with the previous “experiment” that we kept going. With just water and food coloring.

Wondering what she is wearing around her neck? She was pretending to be a puppy and made herself a collar with an old navy tag and a piece of ribbon :)

In each cup she added  two drops of food coloring in different colors. Then some water to see what new color was created.

Again, she was totally mesmerized! I just love kids!! It’s so fun to see her reactions and the joy she finds in the every day things we take for granted.

When she was all done, she mixed all of the cups of colors to make…black.
Ready for even MORE fun science experiments for kids?
I found a bunch of fun projects for kids a couple of years ago for my nieces and nephews and put them together in a Super Science Kit. They loved it and it was a lot of fun to make. I provided all of the ingredients and put them in baggies with a card that had the instructions on it.

This would be a fun summer activity for kids to do as well! You can find all of the fun science experiments I included in the gift, as well as the pdf file for the recipe cards, on my Super Science Kit post.

Our summer has gotten off to a great start. I hope yours has too!

    We do one all the time that is like a combination of the pepper experiment and the food coloring one… Drop a few drops of food coloring of different colors in a shallow saucer of milk (place the drops separately so the colors don’t mix). Put a small drop of dish soap on the end of a toothpick. Touch the soapy end of the toothpick in the center of the food color drops and watch the colors swirl like magic! The dish soap breaks the surface tension where it touches the milk, similar to the pepper experiment, which makes the stronger surface tension in the surrounding liquid pull the pepper/food coloring over to it.

      Thank you! I think the kids would love to try that one. They had friends over tonight and were doing some experiments. We’ll definitely add this one to our list!

    What a fun-tastic idea, especially something fun (and education) to do during the summer break … can you share your kit cards with us?

    Hi! I’d love to do the fizzy color experiment with my students, and wanted to know if I could use your pictures in a PPT presentation that shows the directions to my visual learners. I look forward to hearing from you!
