This was the questions we persued in science last week. Students were given a variety of materials - aluminum foil, mirror, cloth, paperback book, wax paper, etc. They hypothosized if each type of material would cause a reflection. Students then tested the materials and recorded the results. After studying our results, we concluded that shiny, hard, and smooth surfaces cause a reflection. We went on to learn about the Law of Reflection, and we inferred how light waves react when striking various types of surfaces.
Anna checks her reflection in a sheet of aluminum foil.
Garvin checks his reflection on the back of a paperback book.

I know one object that causes a reflection.
A golden apple.
Electronic high five, Mr Brown.
Did Garvin find his reflection in that book cover?
Mr. Brown, I'm so glad I found your blog! This is fantastic stuff! I know you don't need me saying this for motivation, but keep it up!

Stuart - I'll take that electronic high five. And then I'll send one right back to you. How's that?
Mrs. Brewer,
Thanks so much for visiting our blog - I'm glad you're enjoying it. Yes - Garvin DID see his reflection on the back of the book. We were surprised by this discovery! We inferred that because the book cover is smooth and shiny, that it will give a "blurred" reflection. It was a fun experiment. Please come back and visit again!
