Attach one piece of polarizing sheet over the tape. Tape several pieces of tape onto the sheet protector, overlapping several times.
To do this last rainbow experiment you will need Polarizing film sheets, clear shiny tape, and a sheet protector (glossy, not matte). I have another project I will be doing with it soon, too! This last one uses polarizing film sheets. It could also be really cool in a homemade kaleidoscope. I made a pair of glasses with it for my kids, though. It’s not the most cost efficient, but you can find the little glasses in bulk for quite cheap. You can find it on science supply websites or on Amazon. It is called Diffraction Grating (double axis). Remember those rainbow flare glasses that you had as a kid? We got some of the special plastic they use and made our own. The next two require some supplies you likely do not have on hand, but they are fun enough to look into if you are wanting something new and different. The sun shines through the water and casts a rainbow below the glass.
It’s similar to the CD, but with a glass of water. The next one is another super simple experiment with rainbows. You could hold it and let your kids draw the rainbow too! (If you are patient…) I am sure you have some of those lying around… On a sunny day get the sun to reflect right onto the CD and it will reflect a rainbow onto your wall or wherever you shine it. The first rainbow experiment is SO easy and can be done with just an old CD. ( See also my Rainbow Science With Absorption post!) It is a darling book about a little boy trying to find a rainbow outside and the imaginary adventures he has with the rainbow! My kids and I loved this book! These rainbow experiments that we did go perfectly with the book. This week’s book is A Rainbow of My Own by Don Freeman.
This post is part of the Weekly Virtual Book Club for Kids. Rainbow science is amazing and kids love it. Making rainbows with kids is SO much fun! I want to show you some awesome rainbow experiments you can do with kids.
