Physics: Mirror mirror on the wall
This week in physics the kids completed their periscopes and carried out some experiments with lenses and mirrors. In the first experiment the kids placed an object in front of a set of hinged mirrors. The kids observed how changing the angle between the two mirrors affected the number of images produced and tried to figure out the pattern. Then the kids examined a bunch of different lenses, some convex and some concave and noted how looking through each one affected the size of magazine print. One of the lenses they tried out was a drop of water. Convex or concave...what do you think?
