Part A
Stick a fork into each end of the root vegetable as shown. The fork should be
on the same side of the vegetable, and slightly angled away from each other. Play some fort vegetable on the edge of a box or thin wall with the forks hanging down. Does the fourth vegetable balance in the position? Is there any position that works better than the other? Explain
Part B
Consider this question posed at the beginning of the task:
Does Earth’s gravitational force field act on objects that aren’t touching Earth’s surface?
Did the investigation answer the question? Explain whether it gave enough evidence to support the idea
that an invisible gravitational force field exists.
Part C
How might someone dispute the results of your investigation? How might you counter the argument
