All contexts are aimed at years 5 to 10, but many are useful for senior physics (see separate handout ). This presentation focuses on two:

•Cycling Aerodynamics (live now)

•Rockets (coming soon)

“[There is a] need to develop a new form of secondary school science education. This will increasingly depend on both teachers and students having a closer relationship with the science community.”

Cycling Aerodynamics

Cant. U. Wind tunnel

Forces, speed, power

Lindsey Underwood (PhD Stdt)

Streamlining and drag

Canterbury University tests aerodynamics of elite cyclists:

Video: What is rolling resistance

Teaching Approaches

Alison ShanksWorld champion NZ cyclist

Students analyse speed, force and power graphs for the 3000 m individual pursuit in 2008

Teaching Approaches

Students use a hair drier to learn how air flows over different shapes.

A small length of cotton shows if the air flow remains attached (close to the surface = low drag)

Or separates away from the surface showing an area of high drag

TEA: “On your bikes”5 activities

Differentiated /Cooperative

1: How do aerodynamic drag and

rolling resistance affect maximum

speed?

5: Coast down tests

4: How does drag affect terminal velocity as you

roll down a hill?

2: How much force is needed to balance

drag and rolling resistance for a cyclist to travel at a constant

speed?

3: How does tyre pressure affect

rolling resistance?
