Two pencils
Clear tape
Mini Maglite flashlight
Procedure:
Unscrew the top of the flashlight so that the
bulb is exposed. Place on a surface so it is
standing uprightly, about an arm’s length away
from you.
Use a small clear piece of tape (if there isn’t
already) and wrap it around the part of the
pencil that is just below the eraser, where the
arrow indicates above.
Now hold up the pencils, side by side, with
the erasers at the top. There should be just
the slightest gap between them, due to the
tape. Hold about 1 inch from your eye and
look at the light source. Squeeze the pencils
even closer together and see what happens.
Describe what you observe.
Still looking at the light, slowly start turning
the pencils until they are horizontal. Describe
what you observe.
Materials:
• 2 marbles or other weights
• Bucket or pan half-full of water
Materials:
• Tuning forks, at least two of which must

2. Drop both marbles into the pan on
opposite ends at the same time.
Describe what you observe.
3. Drop the marbles again, but this time
closer together. Describe what you
observe.
Procedure:
1. Strike one of the tuning forks. After a
few seconds, stop it with your hand.
Describe what you observe.
2. Have two tuning forks of the same
frequency standing upright. Strike one.
After a few seconds, stop it with your
hand. Describe what you observe.
3. Repeat #2 using two tuning forks of
different frequencies. Describe what
you observe.
