| Sand in Bottles |
| Task: At this station, you will be
determining the different speeds that bottles will roll with
different amounts of sand inside. |
Materials:
- Clipboard
- 2 books, approximately 2-5 cm thick
- 5 bottles labeled A, B, C, D, and X
Directions:
- Make sure that your equipment is set up as shown in diagram
above.
- DO NOT OPEN ANY OF THE BOTTLES IN THIS ACTIVITY.
- Examine bottles A, B, and C.
- Starting at the line on the ramp, allow each bottle to roll
down the ramp once or twice and observe how fast each bottle rolls
down the ramp. Do not push the bottle.
- Record the relative speeds of the bottles in the data table
below. Use the following terms: slow, medium, and fast.
- Based on your observations, write a general statement describing
the relationship between the amount of sand in the bottles and
the speed of the bottles.
- Roll bottle X down the ramp and observe how fast it rolls.
- Use this observation and the information from the data table
to determine how much of bottle X is filled with sand.
In the space below, explain the reason for your answer.
- Use the information from the data table to predict the speed
of a bottle 1/8 full of sand compared bottles A, B, and C. Explain
the reason for your prediction.
- Use the information from the data table to predict the speed
of an empty bottle as compared to the other bottles rolling down
the ramp.
- Bottle D is an empty bottle. Roll bottle D down the ramp. Did
it match your prediction?
What is a possible explanation for why this happened?
