What You Need:
- Laser pointers
- Bullseye printouts
- Handheld mirrors
What Do You Do?
- Thoroughly go over the light and reflection presentation.
- Group the students and have them practice reflecting the laser pointer light from the mirror to the bullseye.
- If time permits, have student groups compete to see who can hit the bullseye the fastest!
Reflection occurs when light bounces off objects. How much reflection depends upon how even the surface is. If the surface is rough, the light scatters. If the surface is smooth and flat, the light will bounce off it at equal angles. That is why a flat mirror reflects a good likeness of the object being reflected.
