Objectives:
- To evaluate a student's ability to make observations.
- To evaluate a student's ability to make inferences based on
their observations.
Questions:
- What kind of motion is made by the object in box A?

- Pick up box C; does it have the same object as box A
or box B?
| Check one: |
Box A ________ |
Box B ________ |
In order for observations to be acceptable they must be
logical for the objects in the boxes. Inferences must be logically
related to student observations.
