These light experiments for kids are fun and easy to do. They’re the perfect way to teach them about how light works and even take it further to talk about refraction and reflection as well. You can also use these activities to talk about circuits and how energy travels to create the light that we’ve all come to need and love.
This list of fun science experiments for kids are a great way to show kids that it’s fun to learn by using hands-on experiments as well. These light science activities are all simple and easy to do and produce really bright and cool results!
Here are some great choices for unique light science experiments for kids.
Light Science Experiments for Kids
Kids love learning about light because it’s something we use everyday. If you’re learning about light, you’ll want to try some of the light experiments on this list!
Get ready to learn fun things about how light works, how shadows work, and where light comes from!
Where Does Light Come From?
Light is a form of energy. Energy is a power by which things move. On earth, most of our light comes from the sun.
The sun is a star. Other stars are too far away from our planet to give us usable light.
Light from the sun can travel by particle or by waves. Its wave form is how we see color. Long wavelengths produce colors like red and orange. Shorter light waves generate blues and purples. All the colors together create white light.
Light travels incredibly fast. Light can travel about 186,282 miles per second. Crazy!
Other light sources can include fire, electricity, and even some animals, plants and minerals can give off forms of light.
