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

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.

This easy at home science experiment uses shortening and ice water to help kids see how animals survive cold winters with fat reserves!

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.

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!

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.

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!

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.

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!

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.

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.
