I have to teach that light travels in a straight line until it hits an object in which it is either absorbed, reflected or refracted. I show that light travels in a straight line by getting 4 different index cards and putting a hole in the middle of the 1st three. Then you line up the cards and shine a flashlight on the holes. The light should go though the wholes and hit the last card. Then we take one of the cards and move it so that the light will be absorbed. This is an investigation from my textbook.
The kids LOVE to see reflection. I normally take the kids to a bathroom that we can turn | |
off all the lights and it has a mirror. I shine a flashlight into the mirror and have the kids find where the light BOUNCES (or reflects) onto the wall. Then we block the light (making shadows). For some reason they like to see the light bounce. It is like they get what reflection means.
