Situations of Work

Scientists have a very specific definition of the term “work”. It involves both force and motion.

You will investigate force and motion

Situations of Work1. Use the Work Station Cards to complete your

investigation

2. Follow all directions and record information in your science journal

3. After you have completed all station cards, quickly create a poster diagramming the assigned work station – include any measurements (see instructions on station card)

4. Be prepared to present your “work” to poster to the class and explain if work has been done.

Work and Forces in Living Things

1. What are some examples of force?2. Does applying a force always cause a change

in position?3. Does a change in position always involve a

force?4. Does work always involve a force?5. Does work always involve a change in

position?

Write questions and write answers using sentences in your science notebook

Describe work using the terms “force” and “distance” in your science notebook.

Corn Seeds - Geotropism

1. Describe the direction in which the roots of the seeds grew.

2. Identify the forces to which the roots are responding.

3. Why do roots grow down?
