| Instructional Materials: | Pushes and Pulls (DW) |
| *Special Instructions: | Discuss the dilemma with the class. Ensure the students understand the characteristics of both paths. |
| MA LS (96 version): | Position and Motion of Objects: Experience and describe how an object’s motion can be changed through the action of a push or pull on the object. |
| MA LS (01 version): | K-2 Physical Science: Demonstrate that the way to change the motion of an object is to apply a force (give it a push or a pull). The greater the force, the greater the change in the motion of the object. |
| BPS LS: | The motion of an object is effected by gravity and friction |
| Technology Connection: |
*The teacher should encourage students to elaborate, give more than the minimum, and strive for a Level 4.
A student response correctly giving the minimum number of responses or details is a Level 3.
In order to achieve a Level 4, a student must go above and beyond what is asked. For example, the student gives more than the required minimum or makes additional connections.
