Continuum of Activities
The list below represents a continuum of activities: resources categorized by Standard/Eligible Content that teachers may use to move students toward proficiency. Using LEA curriculum and available materials and resources, teachers can customize the activity statements/questions for classroom use.
This continuum of activities offers:
- Instructional activities designed to be integrated into planned lessons
- Questions/activities that grow in complexity
- Opportunities for differentiation for each student’s level of performance

Activities
- Define force.
- What is friction?
- What is gravity?
- Below is a picture of Fred pushing a box across the floor. Draw an arrow to show how the box’s motion will change with Fred’s force.
- Summarize the forces that act on a baseball when it is pitched to a batter and is hit to the outfield.
-
How are the forces caused by magnetism and gravity alike? How are they different?
-
When roads get icy in the winter, workers scatter salt or gravel on them. Why do you think they do this? Use facts about motion and forces to explain your thinking.
Answer Key/Rubric
- Force is a push or a pull.
- Friction is the force caused by two objects rubbing together; causes motion to slow down
- Gravity is the force that pulls objects toward the center of the earth.
- Acceptable responses may include, but are not limited to:
- Pitcher throwing baseball toward batter
- Batter hitting ball toward outfield
- Gravity pulling ball toward ground
- Acceptable responses may include, but are not limited to:
- Invisible forces
- Both pull an object (magnetism pulls toward magnet; gravity pulls toward center of Earth)
- Force of gravity cause weight
- Gravity pulls on all objects
- Magnetism only pulls on certain materials
- Acceptable responses may include, but are not limited to:
- Ice makes surfaces slippery. The salt helps to melt the ice so the road isn’t as slippery.
- Rough surfaces create more friction than smooth surfaces.
