How Does Slope Affect the Movement of a Glacier
Purpose:
The purpose of this lab was to find how slope would affect glacier's movement, and whether the movement was at a constant rate or changed.
Hypothesis:
If the slope is more steep, then the glacier's movements will be faster than a less steep slope.
Materials:
Flubber Glue Water Borax
Long tray
Timer
Procedure:
1. Create the flubber.
2. Split the flubber evenly into 2 parts.
3. Roll both parts into balls.
4. Set the tray in three different spots with different slopes and measure the angle.
a. Tray leaning on seat of a chair 15

b. Tray leaning on the top of the desk 43

c. Tray leaning against the top of a lab table 57

5. Define a start and stopping point on the tray.
6. Put the flubber at the start and time how long it takes for the flubber to reach the end point.
7. Record the time for each experiment with different slopes.
8. Compare all three times with different slopes and report out.

°
6 minutes 14 seconds
Top of lab table
57
°
9 minutes 6 seconds
Conclusion: The hypothesis was incorrect; the glacier, or flubber in this case, did not move at a constant rate, for, despite having a steeper angle, the time taken on the lab table took longer than the desk did. The time taken for each angle varied quite a bit; 15° with 14 minutes dropped to 6 minutes with 43°, then it went up 3 minutes with 57°. A glacier may move in the same way as the flubber; it depends on how much snow is gathered on the glacier, as more pressure on the ice of the glacier causes it to move more slowly. An error in this experiment perhaps could’ve been the amount and temperature of the flubber.
