Every day is a new discovery!

Every day is chock-full of new discoveries when you are a kindergartner! These hands-on kindergarten science experiments and activities take advantage of kids’ boundless curiosity. They’ll learn about physics, biology, chemistry, and more basic science concepts, gearing them up to become lifelong learners.

1. Make a lava lamp

Help your students make their very own lava lamp using simple household ingredients. Then personalize the lamps by adding a couple of drops of food coloring to each bottle.

2. Create a tower of ice instantly

Place two water bottles in the freezer for a couple of hours, but don’t let them freeze all the way through. Then, pour some of the water onto a couple of ice cubes perched on top of a ceramic bowl and watch a tower of ice form.

3. Make edible glass

Just like real glass, sugar glass is made from tiny opaque grains (of, in this case, sugar) that when molten and allowed to cool transforms into a special kind of substance called an amorphous solid.

7. Use apples to learn what science is all about

This apple investigation is a great way to start. It encourages kids to examine an apple using a variety of techniques to learn its properties. Get a free printable worksheet for this activity at the link.

8. Paint with salt

OK, kindergartners probably won’t remember the word “hygroscopic,” but they’ll enjoy watching the salt absorb and transfer colors in this neat experiment.

9. Play with “magic” milk

Sometimes science seems like magic! In this case, dish soap breaks down milk fats and causes a colorful swirling reaction that will mesmerize little learners.

10. Race balloon rockets

Introduce little ones to the laws of motion with easy-to-make balloon rockets. When the air shoots out one end, the balloons will sail off in the other direction. Whee!

11. Discover how plants breathe

Kids might be surprised when you tell them that trees breathe. This experiment will help prove it’s true.

12. Explore the properties of mystery items

Mystery bags are always a hit with kids. Tuck a variety of objects inside, then encourage kids to feel, shake, smell, and explore as they try to determine what the items are without looking.

13. Play with fizzing ice cubes

While kinders may not entirely understand the concept of acid-base reactions, they’ll still get a kick out of spraying these baking soda ice cubes with lemon juice and watching them fizz away!

14. Find out what sinks and what floats

Kids learn about the property of buoyancy and get some practice making predictions and recording the results with this easy experiment. All you need is a container of water to get started.

15. Sniff away at scent bottles

Here’s another way to engage the senses. Drop essential oils onto cotton balls, then seal them inside spice bottles. Kids sniff the bottles and try to identify the smell.

17. Watch colored water walk

Fill three small jars with red, yellow, and blue food coloring and some water. Then place empty jars in between each. Fold paper towel strips and place them in the jars as shown. Kids will be amazed as the paper towels pull the water from full jars to empty ones, mixing and creating new colors!

20. Mix up some Oobleck

Perhaps no book leads so perfectly into a science lesson as Dr. Seuss’s Bartholomew and the Oobleck. Just what is oobleck? It’s a non-Newtonian fluid, which looks like a liquid but takes on the properties of a solid when squeezed. Weird, messy … and so much fun!

22. Blow up your fingerprints

You don’t need a microscope to look at fingerprints up close! Instead, have each student make a print on a balloon, then blow it up to see the whorls and ridges in detail.
