CER Problem

Many people ride a bicycle for fun and exercise. Some people ride to work because it saves money and benefits the environment by reducing the use of fossil fuels.

[pic]

Which of these bicycle parts is NOT helping the cyclist to use mechanical energy?

Claim: ____________________ does not help the cyclist to use ___________________ energy.

Evidence: The gear, pedal, wheels, and chain all ___________________. The reflector does not ___________________.

Reasoning: ___________________ energy is moving energy. Since the gear, pedal, wheels, and chain all help the bike to ___________________, they help the cyclist to use mechanical energy. The reflector is used to __________________ light so that it can be seen by car drivers. It is an example of light energy.
