Inverse Square Law
Safety Notes

As with any science lab, you should be careful when doing the Desktop Stars experiments!

General safety tips:

  1. Any jewelry (like necklaces or bracelets) which hangs down should be removed. Jewelry can get caught on lab equipment, and can be an electrical hazard!
  2. Long hair should be put up while doing lab experiments. Hair can get caught in equipment or accidentally touch a hot light bulb or flame.
  3. Do not eat while doing a lab. It is not safe for you or the equipment!.

Safety tips for the Brightness and Distance experiment:

  1. The light bulbs are very HOT and very FRAGILE. Do not touch or bump them.
  2. Watch out for the cords for the lamps. Set up your lamp so the cord is not easy to trip on.
  3. The metal probes on the light meters are sharp. Be careful when holding and using the light meter.

If your light bulb breaks:

  1. Do not touch or try to clean up the broken glass!
  2. Let your teacher know right away that the bulb has broken.
  3. If you can, turn off AND unplug your lamp. If you can not get to the plug without stepping on broken glass, DO NOT unplug the lamp.
