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

Which of these is NOT an example of the bicycle using mechanical energy?

• The pedals, gears, and chain help turn the wheels.

• The wheels turn when the bicycle moves.

• The front wheel guides the bicycle as it moves.

• The reflector allows the bicyle to be seen at night.

A student uses a set of headphones to listen to music. Which of these objects uses the same source of energy as the headphones?

• A flute using wind energy

• A piano using mechanical energy

• A keyboard using electrical energy

• A teapot using thermal energy

A science class is observing a pet turtle in a small plastic pool. The students turn on a portable camping lamp that is clamped on to a counter next to the pool.

Which kind of energy is used by the portable lamp to produce light?

• Mechanical energy, because the lamp is clamped on to the counter.

• Thermal energy, because the lamp increases the temperature of the water.

• Electrical energy, because the lamp is battery-operated.

• Sound energy, because the lamp vibrates when clicked on.

A student recorded the time it took for all the water in a puddle on a sidewalk to evaporate after a rain. Which kind of energy causes water to evaporate?

• Light energy from streetlights

• Sound energy from passing cars

• Thermal energy from the environment

• Mechanical energy from nearby streets
