3. “[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.”

5. Cycling Aerodynamics

6. Cant. U. Wind tunnel Lindsey Underwood (PhD Stdt)
Streamlining and drag Forces, speed, power

12. Canterbury University tests
aerodynamics of elite cyclists:
Video: Testing aerodynamics of elite cyclists
Video: The wind tunnel
Video: Aerodynamics and drag
Video: Testing bike frames
Video: What is rolling resistance

14. Teaching Approaches
Alison Shanks
World champion NZ cyclist
Students analyse
speed, force and power
graphs for the 3000 m
individual pursuit in 2008

15. 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

16. 2: How much force is
1: How do needed to balance
aerodynamic drag and drag and rolling
rolling resistance resistance for a cyclist
affect maximum to travel at a constant
speed? speed?

TEA: “On your bikes”
5 activities
Differentiated /
5: Coast down
Cooperative tests
3: How does tyre
pressure affect
rolling resistance?
4: How does drag
affect terminal
velocity as you
roll down a hill?
