Air Resistance & Friction
Identify the effects of air resistance, water resistance, and friction, and understand that these forces act between moving surfaces to oppose motion
Lesson
Set out your lesson
“Air Resistance & Friction means forces that oppose motion between moving surfaces—air resistance, water resistance, and friction. We will compare falling paper, sliding on smooth vs towel, then check a fresh opposing-motion idea.”
Bring to the table
- Two paper shapes: flat sheet and crumpled ball (same paper amount)
- A toy car or block plus a smooth tray and a towel (friction contrast); optional bowl of water for a gentle water-resistance dip with adult
Extra for the adult
Worked example. A flat sheet falls slower than a crumpled ball because of air resistance. A towel adds friction that slows a slide.
Optional challenge. For Air Resistance & Friction, design a paper “parachute” and compare drop times with adult timing.
What to notice. Keep one parent note: demos; opposing-motion language; support used. This session samples resistance forces, not mastery of physics equations.

Air Resistance & Friction means forces that oppose motion between moving surfaces—air resistance, water resistance, and friction. We will compare falling paper, sliding on smooth vs towel, then check a fresh opposing-motion idea.
Spend about 13 minutes showing air resistance and friction opposing motion, then checking one fresh example.

Check understanding
- Define air resistance, water resistance, and friction as forces that oppose motion
- Give everyday examples of each force and explain how they slow things down
- Describe how these forces depend on factors like speed, surface area, or surface texture
“Can your child explain why a parachute slows you down, why swimming is harder than walking, and why bike brakes use rubber pads?”
