Hot Hats

CSEF · 2010 Materials Science (Junior Division Only)

Kurtis D. Dwinell, Steven Ellison · Sierra Primary School, Herlong, Lassen County

Overview

Objectives/Goals Was there any differences between the types of fabrics used, and the amount of protection from the ultra violet rays that came from the sun. Methods/Materials Tested with a ultra violet sensor the amount of sun rays that pentrated through the different fabrics of baseball caps. I used a baseball cap of 100% cotton, a baseball cap of 100% wool, and a baseball cap of 100% acrylic. Results There was no mesurable difference between the different fabrics of the baseball caps, and the amount of ultra violet rays. Conclusions/Discussion A cap, or hat of any fabric will significantly block ultra violet rays from the sun.

Summary statement

I tested fabrics to determine if there was a difference in the amount of uv rays blocked from the sun.

Help received

My teacher, Mrs Paque, gave me instructions.
