Teresa's Testing Suncscreens Science Experiment
Materials needed: Sun print paper, 3 sunscreens, transparent plastic or glass, dark cover sheet.
Testing actual products is a fun way to learn science with a practical application. Ever put on sunscreen then wondered why you burned anyway? They loose their effectiveness after about 1 year. So if you intend to use your leftovers from last year, you're taking a chance on not getting the protection you need. For this experiment, you can do two different tests. You can test 2 of the same brand of sunscreen, one purchased over a year ago and a new one or you can use it to test 3 good, not out of date sunscreens. I suggest you borrow from other families and choose some that was purchased during the summer or near the end of it, since this stuff is expensive and looses it's effectiveness. You will need to purchase sunprint paper. This paper fades quickly in sunlight leaving designs where you cover it. Be sure not to remove the paper from it's dark covering when it arrives. I was able to find a set on the internet (google=sun print paper) that gives you plenty for cheap, large sheets and lots left over to play with for only $11.
Then when you're finished with the follow up on this, here's some craft ideas for art work you can make with the left over sunprint paper.
You'll also need a clear plastic sheet like a transparency film sheet. You can also use clear plastic sheet covers, the pockets that go in notebooks, just make sure they are perfectly clear, not opaque. OR you can use glass, like something from a cheapo picture frame from the thrift store for 50 cents. You will also need a piece of paper that is dark and is the same size as your print paper. Most packages come with one.
Lastly you need sunscreens. Make sure you test a store or no-name brand.

Welcome to the
World of Home Education and
We began educating our children in 1985, when our eldest was five. In truth, we had helped them learn what they need to learn since they were born. I am a passionate advocate of allowing children to learn unhindered by unnecessary stress and competition, meeting developmental needs in ways that suit their individual learning styles and preferences. Ours was a homeschooling, unschooling and natural learning family! There are hundreds of articles on this site to help you build confidence as a home educating family. We hope that your home educating adventure is as satisfying as ours was! Beverley Paine
