Big Idea 13: Forces and Changes in Motion

A. It takes energy to change the motion of objects.

B. Energy change is understood in terms of forces--pushes or pulls.

C. Some forces act through physical contact, while others act at a distance.

Clarification for grades K-5: The target understanding for students in the elementary grades should focus on Big Ideas A, B, and C.

Clarification for grades 6-8: The target understanding for students in grades 6-8 should begin to transition the focus to a more specific definition of forces and changes in motion. Net forces create a change in motion. A change in momentum occurs when a net force is applied to an object over a time interval.

Grades 9-12, Standard 12: Motion - A. Motion can be measured and described qualitatively and quantitatively. Net forces create a change in motion. B. Momentum is conserved under well-defined conditions. A change in momentum occurs when a net force is applied to an object over a time interval.

Lesson Plans

Let's Use Force:

The students will be able to explain how a push or pull affects how an object moves, the difference of a push and pull, and the way to change how something is moving is to give it a push or a pull.

Type: Lesson Plan

All Aboard! Pushes and Pulls:

After completing performance tasks in science on pushing and pulling, students will have an opportunity to apply their new learning to reading informational text about vehicles that can push and pull. This lesson focuses specifically on pushing and pulling of trains by the engine.

Type: Lesson Plan

Teaching Ideas

All About Motion:

Students will observe and discuss motion in learning stations or in demonstration. They will observe and discuss how a push or pull affects motion.

Type: Teaching Idea

How and Where Things Move:

Students explore a variety of objects to discover the many ways the objects move-up and down, straight line, in circles, back and forth. They will discover that a force (push or pull) makes it move.

Type: Teaching Idea

Investigating Motion With Marbles:

In this guided inquiry activity, students will use 2 marbles of different size and a box to investigate what makes the marbles move and what will cause the marbles to change speed and direction.
