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.”

Teaching Approaches
Alison ShanksWorld champion NZ cyclist
Students analyse speed, force and power graphs for the 3000 m individual pursuit in 2008
![Page 15: 15.30 o6.1 s chrystall](https://reader035.vdocuments.site/reader035/viewer/2022062418/555836d3d8b42ac6078b48ce/html5/thumbnails/15.jpg)
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?
