Discuss with the students the aerodynamic benefits of sitting in
certain positions when riding a bicycle. Also, discuss the safety and
drag reduction when wearing a helmet and having certain type handlebars.
Talk about the various bikes that are available today and their uses.
|
|
Talk about safety ahead of time during the bicycle trials.
|
|
Proceed to the area where you are going to race the bicycles.
|
|
Have the area coned off where you want the students to race the
bicycles. Have two students race at the same time and same distance,
using similar bicycles and helmets. Have one student in the crouched
position with a flat back and the other student sitting up straight.
Observe what happens to the two cyclists. Who has the fastest time?
(Pair the students up according to biking ability and speed ability.
|
|
|
|
Repeat the race using two different types of bicycles, and one
student wearing a helmet and the other one not. Have both students in
the crouched position and time their speeds. (Pair the students up
according to similar biking ability and speed ability).
|
|
Use different combinations of testing until each student has an
opportunity to participate at least twice. You can use students to
assist you with timing and recording results.
|
|
Return to the classroom and discuss the dynamics that have taken
place during the races. Chart the findings on a graph and display on a
Bulletin Board.
