- Gender
- Males need more
energy than females
- Activity Levels
- More active people need more

- To show the conversion
of energy into heat
- 1. Place thermometer in water in a
test tube that is in a retort stand
- 2. Hold a burning piece
of cracker under it.
- 3. Note the temperature of the water rising.
- 4. This shows that the chemical energy in
the cracker is converted to heat energy
