Newton's Laws Stations Activity
Deep Impact (student handout)
Materials:
• Fine-grained sand
• Flour
• Golf ball
• Marble
• Tray
Step-by-Step Procedure:
1. Use the triple beam balance to weigh the marble and golf ball. Record their masses.
2. Lay the paper down on the working surface.
3. Fill a small tray with sand and sprinkle a very thin layer of flour on the surface.
4. Drop the marble onto the sand from a height of about 20 cm.
5. Measure the diameter of the marble. Record the diameter, the height of the drop,
and any observations from the drop in the table below.
6. Measure and sketch the diameter of the impact.
Hypothesis:
Based on what you know about Newton's laws, predict what you expect to happen if you drop the golf ball from the same height.
Will the hole be deeper or shallower?
Using this information, form a hypothesis that includes your reasoning. You can use the following template…
Based upon Newton's ________________________________________________ law,
the golf ball will ________________________________________________ because ___________________________________.
TEST IT.
1. Smooth the surface of the sand and sprinkle another fine layer of flour on it.
2. Drop the golf ball onto the sand from the same height as in Part 1.
3. Measure the diameter of the golf ball. Record the diameter, the height of the drop, and any observations from the drop in
the table below.
4. Measure and sketch the diameter of the impact.Explain your results using Newton's laws.
