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)

•Over 100 NZ scientists and 50 organisations in action on SLH so far…(showcases Nature of Science)
•Involves all New Zealand Universities, CRIs and many independent research companies
•Intended to engage NZ students•Free articles, videos and teaching ideas•Funded by the New Zealand government•National project of collaboration managed by the University of Waikato

“[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.”

Streamlining and drag
Canterbury University tests aerodynamics of elite cyclists:

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?
