At Home Water Science Activities for Kids
September 22, 2020
Are you looking for fun and interactive outdoor projects to work on with your kids? Then start by gathering some everyday items from around your home so you and your kids can perform these simple water science projects. Teach your kids the science of water with these fun projects!
1. Basic Water Science Experiments
- Floating vs. sinking: Gather some of your child’s favorite toys along with other household items — measuring cups, plastic toy animals, small plastic cars, blocks, an egg, and coffee filters. Fill a bowl with water and drop the items into the bowl to see which sink and which float. Older children can make predictions about which they think will sink or float.
For an advanced water science trick, show how the egg sinks when placed into the water alone but floats when sitting on the coffee filter.
- Air bubbles: Show the magic of water by experimenting with air bubbles submerged in water. Stuff a piece of a paper towel into the bottom of a small cup. Then, with the top down, submerge the cup in the water inside a bowl. When you take it out of the water, have your child try to explain how the paper towel stays dry.
- Colored bubbles: Drop food coloring down the side of a clear cup. Submerge the cup, top down, into the bowl or tub of water. Watch as the colored dye dissolves into the water, but above, the air bubble stays in place.
2. An Anti-Gravity Water Trick
You will only need a glass, a t-shirt and water for this science trick. To begin, place the cloth over the mouth of the glass, then use your finger to press a slight indent into the fabric. This will help the glass fill with water and dampen the material. Then, fill the glass about three-quarters full of water, and pull the fabric tight over the cup.
At this point, you have two options — either flip the glass quickly, using one hand to hold the fabric tightly, or place one hand over the top and use the other to hold the material and slowly turn the glass upside down. Either way, you will notice the water will not pour out. This trick uses gravity and the high surface tension in water to keep everything in place using the cloth. Now, see what happens to the water if you dab detergent or other liquids on the cloth.
3. The Pepper and Water Experiment
The pepper and water science experiment explores the surface tension of water. For this project, you will need a shallow dish, pepper, dishwashing liquid, and water.
Fill the dish with water and sprinkle pepper over the top, then dip your finger in the water — nothing will happen. Then, do the same with a bit of detergent on the tip of your finger, and watch as the pepper retreats to the edges of the plate. With the detergent addition, the surface tension of the water is lowered.
