SCIENCE CONCEPT:

Newton's First Law of Motion: objects at rest remain at rest and objects in motion remain in motion unless acted upon by an outside force.

STUDENT OBJECTIVE:

The student will discover a part of Newton's First Law of Motion: an object at rest remains at rest unless acted upon by an outside force.

OVERVIEW:

The student will run and stop at a designated spot to discover that an object in motion remains in motion unless acted upon by an outside force.

TEACHER TEXT:

PREPARATION TIME: 5 minutes

LESSON TIME: 10 minutes

TEACHER PREP:

Gather materials.

Locate a "running" space of at least 10 feet.

WORDS TO KNOW:

• run
• stop
• line
• continue
• motion

MATERIALS NEEDED:

• indoor or outdoor running space (at least 10')
• masking tape or chalk

STEPS TO FOLLOW:

1. Using tape or chalk, mark a start and stop line on the floor or ground at least 10' apart.
2. .From the start line, run to the stop line without slowing down. Stop when you reach the stop line.
3. What happens? (You may be able to stop your feet, but your upper body will continue to move forward.)

WHY?:

Objects that are moving tend to keep moving. This is called inertia and is part of Newton's First Law of Motion..

ASSESSMENT: Can the student communicate what they observed?

4.... The student is able to communicate that it was hard to stop because objects in motion tend to keep moving.

3.... The student is able to communicate that it was hard to stop because they were running fast.

2.... The student is able to communicate that it was hard to stop.

1.... The student is able to communicate that he/she ran from one line to another.
