Red and Green cellophane
Flashlight
Black box with hole in one side
Red playing card
Banana
Green apple
1. Place the objects in the box. Place the green
cellophane over the top of the box and shine
a flashlight through the hole in the side.
* The banana and the apple both reflect
green light.
* The red playing card doesn't reflect
green light, so the red on the card
appears black.
2. Do the same thing, but use
the red cellophane.* The banana reflects the red light,but the apple doesn't.
* The card reflects all colors, so now it looks red.
(Sam and I tried this with another color of red and it didn't work, but she found this one and it worked perfectly).
Why does the red on the playing card appear black when the green cellophane was used?
ReplyDeleteGreat Job! I like how you all were creative when needing a different kind of red paper. Your explination was terrific and helped get the idea across for your experiment.
ReplyDeleteGreat job! Would this have worked with other objects? It would be fun for students to try various objects and colors of cellophane to see which ones will work.
ReplyDeleteI agree Jessica, it would be fun to use different objects and different colors of cellophane to see what happens!
ReplyDeleteI loved the extra information that you provided after the experiment pictures and observations. It was also neat how you used a gift bag instead of what was listed in the book. Could you have used different colors? Wonderful work ladies.
ReplyDeleteGreat job!!! It was interesting to see the red writing on the card disappear. Wonder what yellow cellophane would do, especially with the banana?
ReplyDeleteThis looks really cool!! I think it would be really fun and educational! Great job!
