Easy Science Experiments to Do at Home (With Videos!)

Kelly R. said:  My kids loved this easy do at home science experiment, which uses sugar and water to teach about saturated and supersaturated solutions. It doesn't hurt that you get to eat the results!

Shila said:  This is a cool science experiment where soap traps oxygen gas to create an expanding colorful foam. Don't skip the food coloring!

Shila said:  This easy science experiment for kids is a groovy lesson in density and polarity. You can save your lava lamp potion and reactivate it by adding more Alka Seltzer tablets!

Kelly R. said:  For a much more exciting spin on the traditional baking soda and vinegar reaction, this is the perfect easy science experiment to do at home. Kids learn about the acid/base reaction with an explosive payoff!

Shila said:  You can use cups and string to create an easy science experiment that teaches kids about how sound waves travel. The telephone is also just fun to play with when you're done!

Shila said:  This easy science experiment (and art project!) demonstrates surface tension in such a fun way. Use multiple different colors for the coolest effect.

Kelly R. said:  Use household objects to build a container to protect an egg, and drop it from a height to test it out. Get creative! Drinking straws, paper, cardboard tubes, cotton balls, popsicle sticks, string, baggies, tape - anything is fair game for this easy to do at home science project and STEM activity!

Shila said:  This fun science project makes a cool and tasty treat and is a great summer bucket list activity to try as a family! Experiment with different flavors or mix-ins, and see if it works as well using different types of salt.

Shila said:  The chemical reaction between vinegar and baking soda in this easy science experiment will yield a quick-fizzing, bubbly carbon dioxide gas that will erupt out of your homemade volcano!

Shila said:  This cool science experiment is a lesson in density! Kids use Skittles and water to create colorful layers with different densities.

Alexandra F. said:  Cut a few stalks of celery by the white root. Add 20-25 drops of food dye into a vase or large glass with about 6-8 ounces of water. Blue food coloring works the best! Insert the celery (with leaves still intact) into the vase and observe after 36 and 48 hours. The leaves should appear more vibrant than before in a bold new color.

This easy science experiment for preschoolers helps them visually learn how plants "drink" water by adding color to the process! From Teaching Tiny Tots

Shila said:  For this easy science experiment, mix the juice of half a lemon with one spoonful of water in a bowl. Dip a Q-tip in the mixture and write a secret message on a piece of paper or cardstock. Let your message fully dry and become invisible. Carefully iron directly on the paper to help the message reappear. Don't use the steam function. You could also write a decoy message with pen first!

Heat breaks down the carbon components in the lemons, causing them to change color and oxidize in the air.

Kristy Pepping said:  If your kids are interested in weather and wonder how tornadoes form, a great way to demonstrate this phenomenon is with an empty two-liter soda bottle. You can have kids record how fast water drains out just by holding it upside down when full of water. Then have your children swirl the bottle and see how fast the water comes out.
