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

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!

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

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.

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.

Shila said:  An easy DIY sundial clock can be a "full day" outdoor activity and science experiment for kids! Learn to tell time using the sun and a few common household objects. From Scientific American

Shila said:  This easy at home science experiment uses shortening and ice water to help kids see how animals survive cold winters with fat reserves! From Discover and Learn Preschool

Shila said:  This easy chemical reaction science experiment uses simple ingredients found at home: vinegar, baking soda, and a surgical glove wrapped around a drinking glass. As the baking soda reacts to the vinegar, the bubbles rise and fully inflate the glove. From National Geographic Kids

Shila said:  You'll make a surprisingly mess-free craft for kids with this easy to do at home science experiment. Kids use permanent markers and rubbing alcohol to learn about solubility.

Shila said:  Make a mini greenhouse and watch seeds sprout. All you need are seeds, water, sunlight and a paper towel in a plastic ziplock bag. This easy science experiment is often used in preschools so kids experience a better visual of a seed's life cycle, and is also a great activity for toddlers and preschoolers at home!

Shila said:  Pennies can be used in a science lesson for kids in metals and chemical reactions. Pennies are made of a copper finish that becomes tarnished over time. Common household acids (like vinegar with salt) can effectively transform dull pennies back to bright and shiny coins! This experiment shares a few safe techniques. From Sciencing

Shila said:  Give your children a magnet and have them discover (and write down) which appliances/door handles/air vents/desk supplies/tools around your home are magnetic. Have a small reward awaiting the winner who captured the most finds! You can simplify this by having a prepared checklist list for them, too. Along with the lesson in magnetism, it's a fun indoor activity for a rainy day!

Kristy Pepping said:  Arrange M&Ms in a tight circle around the edge of a paper plate. Carefully pour water into the center of the plate, stopping once the water reaches the outer edge of the candy. Watch the water dissolve the candy coating and make a rainbow of color! Test out different water temperatures. Does ice water or warm water work better? Could this be why M&Ms melt in your hands, too?!

Shila said:  Using a blindfold, kids can challenge their senses (and each other) to a smell test using common household spices and safe pantry ingredients (cinnamon, cocoa powder, oranges, etc.). Be sure to practice safe techniques, including avoiding inhalation. Hold the testers slightly away from your face and use your hands to waft the smell towards your nose.

Alexandra F. said:  This awesome tutorial takes the baking soda and vinegar reaction that is a favorite of many science experiments for kids, and makes it even MORE fun by using it to power a LEGO car! From Frugal Fun 4 Boys and Girls

Alexandra F. said:  Simply fill a large, clear container with water. Then, ask your toddler to find different objects to put in it, and to guess whether they will sink or float. Try using legos, balls, corks, toy cars, fruit, cups, spoons - really any small object that you can safely immerse in water!

This is a great at home experiment for toddlers and preschoolers, and provides a fun visual lesson in density! Objects that are less dense than water will float, and those that are more dense than water will sink. Shape also plays a role - if more of the object is touching the surface of the water it will be more buoyant and likely to float.

Shila said:  When you add raisins to a glass of carbonated soda, they'll initially sink but will begin to rise and fall as carbon dioxide bubbles make them buoyant and then pop at the surface.
