If I were to make a list of what kindergarten kids love the most my guess is that fun, learning, and activities with water, would definitely be on that list. So why not combine all these into an amazing science experiment?

Preschoolers are very active and curious, the best way for these young individuals to learn is to show them something that is fascinating, fun, and safe for them to observe or better yet, participate in. Here are some experiments that kindergarten kids can do with the use of water. 

fun water science ideas for kindergarten age kids

The Water Bottle Tornado

This experiment requires very few supplies and it can actually produce a very fascinating result. It will not just entertain the kids, it can also help you introduce them to the weather. In order to do this science experiment, you will need to have water, regular dish soap, and a tall, transparent water bottle.

Fill the water bottle with water, and add a squirt of dish soap. Give the water bottle a whirl and watch as you create a powerful mini tornado inside. This experiment is a lot of fun and it is also very easy for the kids to do. When doing this experiment, you can talk to the preschooler about the weather and about tornados, you can also let them watch YouTube videos about this topic.

The Rain Experiment

Another fun activity that you can show to your kindergarten kids is the rain experiment. You can do this by putting hot water in a jar, covering the jar with a plate, and by putting ice cubes on top of the plate. This experiment will show kids how to make it rain inside the jar. The cold plate will meet with the hot air inside the jar, condensing it and making water droplets. With this experiment, you are basically creating a miniature cold front.

Because of the use of hot water, the children will have to be carefully supervised when doing this experiment. You must be very careful when putting hot water inside the jar and you need to make sure that the jar will not spill over. There is no need for you to use boiling water to do this experiment.

The Hole In The Plastic Bottle Trick

This trick is very amusing simply because it will make the kids think and wonder. It can help stimulate their brains and at the same time, it can also help them know a bit about pressure, and about how wonderful things can be achieved through science.

You can do this experiment by making a hole on the side of a plastic soda bottle. You can use an ice pick to do this. Cover the hole with your finger and fill the plastic bottle with water. Screw the cap back on and release your finger. With this experiment, you will see that because there is an equal amount of pressure inside and outside the plastic bottle, the water will not flow outside. You can open the cap to let the water pour out of the hole.

This experiment is also a neat trick because you can actually squeeze the plastic bottle and for as long as the cap is still screwed tightly, the water will not flow out. But it can easily turn into a lighthearted prank as soon as someone will try to open the bottle without knowing about the experiment.

Making Gigantic Bubbles

Have tons of fun with the kids outside the house or at the schoolyard with the help of this secret formula that will allow you to create gigantic soap bubbles for everyone to play with. In order to do this activity, you will need to have 6 cups of distilled water, half a cup of cornstarch, 1 tablespoon of baking powder, and 1 tablespoon of glycerine. Combine all these ingredients together and put it inside a container that can fit large wire loops so you can create extra-large bubbles.

What is great about this activity is that you can introduce your preschoolers to a bit of chemistry as they mix different ingredients together. This experiment will also allow you kids to have tons of fun outdoors as they will surely have a blast making huge bubbles and playing with their friends.


Having science experiments with water is a great way to introduce the kids to different things. It will allow the kids to participate in something new and it can also help stimulate their young minds by fueling their curiosity and by directing their energy towards something new.

There are actually hundreds, if not thousands of science experiments that you can do with your kids, just make sure that the little ones are properly supervised especially when there is a need to use hot ingredients, harsh chemicals, or sharp objects.
