Colored Light Science Experiment

By -
Light is the perfect experiment tool for preschoolers...and older kids too!



We are surrounded by light!  As young as infants, babies are fascinated by light and dark objects.  As they grow older, their curiosity about light only increases!  You can feed this curiosity by letting your kiddos experiment with light.  This is super easy if you just have a flashlight!  If you don't, you can grab one for as little as a dollar.  If you're in a classroom, grab a set so (at the least) your kids can experiment in groups of 2-4.  Other fun (but optional) supplies include mirrors, clear colored plastic, colored tissue paper, and colored balloons.



I start out by turning out the lights and shining a flashlight around.  Look at the shadows and wave the light on the ceiling or floor.  See if your kids can "catch" the light as you move it around!


Then show them how the light passes through some things and not others.  Ask what happens when it passes through colored objects.  Then show your kiddos the objects they're allowed to experiment with, pass out the flashlights, and let them get to work!  Be sure to review any rules you feel are necessary--usually we need to talk about not shining light in people's eyes.


My kids can experiment with flashlights for over an hour!  When they're done, let them tell you their favorite part or what they saw (observed)!

Science Experiment: Elephant Toothpaste

Update: "Elephant toothpaste" is a science experiment that I used to do with my high school students.  It is a strong multi-sensory demonstration that goes great with a lot of chemistry concepts. It is also very popular with preschoolers and homeschoolers!  The internet loves it too! It has now been read by more than 3.9 million people! This was the post that started the trend on science activity sites across the internet and "irl!"  Thank you for being here...I hope you enjoy it as well!  💕  This exciting science experiment works great in a discussion on reactions, as a demonstration, or as an actual experiment. We've also done seasonal twists with "elephant toothpaste" like making it in a pumpkin and using it for " reindeer toothpaste !" To use it as a science project, perform it once with your child, then ask your child what might happen if you changed the amounts or left out an ingredient.  Any time you experiment...

This sensory lesson includes a kindness activity for kids that is short and sweet,  and makes teaching kindness a beautiful thing! Learning to use kind words with our friends is one friendship lesson that I think we can never cover enough...kids always need reminding (sometimes adults do too)!  You will need these simple supplies for the kindness activity: cotton balls, course sandpaper, cup, Should I Share My Ice-Cream by Mo Willems Directly teaching good friendship skills, like using kind words, serves two purposes: 1- You can refer to the lesson when someone forgets or needs reminding, and 2- These skills are not intuitive for all preschoolers. This is a perfect age to bring empathy and kindness to their attention and help them cultivate these skills! You can use this lesson plan exactly as I did it with our kiddos, or adapt it to fit your group! 1- Read  Should I Share My Ice-Cream  by Mo Willems.   {Image below is an Amazon Affi...

Do you know what color giraffe skin is? Today we're using a capillary action science experiment to make our own giraffe skins in this fun giraffe science experiment project! (Read on...I'll tell you the color in a moment! AND I have a few more fun giraffe facts at the end! Anyway, go on and make a guess before you see the answer!) Fun Spot  Giraffe  Fact:  There are four different giraffe species:  the Masai Giraffe, the Rothschild Giraffe, the Somali Giraffe, and the Nigerian Giraffe.  Each has its own unique spot pattern.  Even more unique, every single individual giraffe has a different spot design.  Just like fingerprints on people and stripes on a zebra, spots on a giraffe are unique in every individual! Giraffe skin is mostly grey. (Were you right?) It's also really tough and thick.  The coat is a shade of tan with brown spots or patches.  Male giraffes actually get darker as they get older! To make our "giraffe ...
