Free Science Experiment for High Schoolers: Measuring Light Speed with Chocolate
I have another fun and free science experiment to share with you today - and this one is aimed at the older kids (but easy enough for younger siblings to follow along too!)
Want more science freebies? Take a look at my Science Printables page!
I found this experiment for my 8th grader who is currently studying space and astronomy. I wanted to make up an experiment we could include to go along with her unit on light and space, but nothing too complicated or requiring any outdoor time (it's cold here this time of year!).
All you'll need is a microwave, a plain chocolate bar, a calculator and a ruler! I have also included a pre-knowledge sheet for this experiment that explains how light is measured, how microwaves use light waves and even included a video from Youtube about how microwaves were invented and work.
Since the experiment follows the scientific method, this means that kids will need to come up with a question for their experiment. If they get stuck, I have included some that they can use or to help get them thinking up their own questions.
Of course, the best part of this experiment is that your kids will get to eat some chocolate afterward!
You can download this freebie below by clicking on the link - it will take you to the file on dropbox. You can feel free to use this in your homeschool, classroom or online classes as long as you leave my website on each page and follow my terms.
Enjoy learning - and some chocolate!
