Lesson #: 2-4 What is air resistance?

Objective: Explain how air resistance affects falling objects.

TechTerms: Anticipatory set: video and ask them what they know about air resistance.
 * Air resistance**: force that opposes the movement of an object in air
 * Terminal velocity**: speed at which air resistance and gravity acting on a falling object are equal
 * Vacuum:** empty space

Instructions: 1. View video and ask questions on what was seen about air resistance. 2. Do experiment- what falls faster? Split into 4 groups, each given 3 objects to test. 3. Write 2- to 3 sentences on what was learned about air resistance. 4. Tell about Vacuum. (see tech terms) 5. Do questions.

Guided Practice: Group experiment- What falls faster?

Closure: Quiz w/ optional question at end.

Assessment: Quiz.

Possible extension: Test other objects at home.
