Water experiments aren’t just for summer! Water is such an easy and budget friendly item to use for science learning with preschoolers and elementary age kids. We love simple science experiments that are a breeze to pull off, simple to set up, and kids love! What’s better than that!
FUN WATER EXPERIMENTS FOR KIDS
SCIENCE EXPERIMENTS WITH WATER
What do all these science experiments, and STEM projects below have in common? They all use water!
These water experiments are perfect to do at home with household items. Also, check out our science experiments with baking soda.
If you want to explore science with water as the main ingredient, let’s dig in! While you’re at it, make sure to check out more kid friendly science experiments and activities.
Our science activities and experiments are designed with you, the parent or teacher, in mind! Easy to set up, quick to do, most activities will take only 15 to 30 minutes to complete and are heaps of fun!
USING THE SCIENTIFIC METHOD
The scientific method is a process or method of research. A problem is identified, information about the problem is gathered, a hypothesis or question is formulated from the information, and the hypothesis is put to test with an experiment to prove or disprove its validity. Sounds heavy…
What in the world does that mean?!? The scientific method should simply be used as a guide to help lead the process.
You don’t need to try and solve the world’s biggest science questions! The scientific method is all about studying and learning things right around you.
As kids develop practices that involve creating, gathering data evaluating, analyzing, and communicating, they can apply these critical thinking skills to any situation. To learn more about the scientific method and how to use it, click here.
Even though the scientific method feels like it is just for big kids…
This method can be used with kids of all ages! Have a casual conversation with younger kiddos or do a more formal notebook entry with older kiddos!

NEW! ICE IS NICE SCIENCE
Explore the solid form of water, ice. Take a look at three great experiments using ice that highlight the scientific method perfectly!
CANDLE IN WATER EXPERIMENT
Can you make water rise by burning a candle under a jar? Grab a few simple supplies and find out.
CELERY EXPERIMENT
Here’s a simple way to explain how osmosis works with celery and water.
COFFEE FILTER FLOWERS
Water is the main ingredient in this gorgeous but super easy combined science and art activity. Make a bouquet of colorful, coffee filter flowers and explore solubility too!
COLOR CHANGING FLOWERS
This engaging color-changing flower experiment explores the concept of capillary action as your flowers magically turn from white to green. Easy to set up and perfect for a group of kiddos to do at the same time or as an interesting water science fair project.
CRUSHED SODA CAN EXPERIMENT
What happens when you heat and cool water inside a soda can?
DISSOLVING CANDY
There are all kinds of fun things you can dissolve in water!
DRY ERASE MARKER EXPERIMENT
Is it magic or is it science? Create a dry erase drawing and watch it float in water.
HOW DO SHARKS FLOAT?
Explore buoyancy with this simple oil and water experiment.
HOW MANY DROPS OF WATER ON A PENNY?
All you need for this experiment are a few coins, an eyedropper or pipette, and water! How many drops fit on the surface of a penny? What else could you use? A bottle cap turned over, a flat LEGO piece, or another small and smooth flat surface! Take a guess at how many drops it will take and then test it out.
ICE MELT ACTIVITIES
Playful hands on science and learning which is perfect for our preschoolers. Explore water science with one of these fun theme ice melt activities.
LEGO WATER EXPERIMENT
Build a dam from Lego bricks and explore the flow of water.
OCEAN CURRENTS
Build a simple model of the ocean currents with ice and water.
OCEAN LAYERS
Just like layers of the earth, the ocean has layers too! Have you ever wondered how you could see them without going scuba diving in the ocean? Explore the layers of the ocean with a liquid density tower experiment for kids.
OIL AND WATER EXPERIMENT
Do the oil and water mix? Explore the densities of liquids with this simple oil and water experiment.
RAINBOW IN A JAR
Can you make a rainbow in a jar? This neat rainbow water experiment explores water density with just a few materials. Instead of salt we use sugar and food coloring to stack the colors of the rainbow.
PENNY BOAT CHALLENGE
Design a simple tin foil boat, and see how many pennies it can hold before it sinks in the water. How many pennies will it take to make your boat sink?
SALT LAVA LAMP EXPERIMENT
Explore what happens when you add salt to oil and water.
SALT WATER DENSITY EXPERIMENT
Can you make an egg float? Will different items sink in freshwater but float in saltwater? Compare saltwater to freshwater with a fun experiment with salt and water. Make your predictions and test your results.
SINK OR FLOAT EXPERIMENT
Check out what you have in the kitchen for an easy science experiment with water with some very interesting results!
SKITTLES EXPERIMENT
A super simple water science experiment with everyone’s favorite candy! Did you know you can try it with M&Ms too? You can also you those red and white mints, old candy canes, and even jelly beans!
SOLID LIQUID GAS EXPERIMENT
Learn about the properties of solids, liquids and gases with this simple water experiment. Have fun observing how water changes from a solid to a liquid to a gas.
STRAW BOATS
Design a boat made from nothing but straws and tape, and see how many items it can hold before it sinks in the water. Explore buoyancy while you test out your engineering skills.
TOOTHPICK STARS
Make a star out of broken toothpicks by only adding water. Learn about capillary action with a totally do-able water experiment.
WALKING WATER EXPERIMENT
Can water walk? Make a colorful rainbow with a little color theory mixed in too! This walking water experiment is super easy and fun to set up! Mason jars, plastic cups, or bowls will also work just fine for this experiment.
WATER CYCLE IN A BOTTLE
Make a discovery bottle all about the water cycle. One of the best water science activities is one where we can learn more about one of the most important and necessary cycles on Earth, the water cycle!
WATER CYCLE IN A BAG
The water cycle is important because it’s how water gets to all the plants, animals and even us!! Learn about the water cycle with this easy water cycle in a bag experiment.
WATER DISPLACEMENT EXPERIMENT
Get ready to add this simple water displacement experiment to your science lesson plans this season. Learn about water displacement and what it measures.
WATER XYLOPHONE
A homemade water xylophone is a perfect way to explore physics and sound science!
WATER ABSORPTION EXPERIMENT
This is a very simple and fun water experiment my son had a blast exploring. It will really get your kids thinking about what materials absorb water and what don’t.
