This week we split up into groups and out hypothsis was diffrent refletctivity on diffrent objects. we did the tests on a wall, paper, cloth, metal, wood, water, glass, and a mirror. Our prediction was that we thought that it will reflect off transparent objects and not opaque objects. our results were

wall: 5 for brightness 5 for size 0 for reflected it was small when close and big when far

paper: 5 for brightness 3 for size 0 for reflected

cloth: 5 for brightness 3 for size 0 for reflected

wood: 5 for brightness 4 for size 2 and a half for reflected

glass: 4 for brightness 2 for size 5 for reflected

water: 5 for brightness and 3 for size and 0 for reflected

mirror: 5 for brightness 4 for size and 5 for reflected

metal: 4 for brightness and 5 for size and 5 for reflected

We also learned about angle of incidence and angle of reflection.

we learned what an analogy was and how to use them with science.
