Activity: Day to Day Conversion Devices
Most of the day-to-day devices that we use are energy conversion devices. In this activity, you will identify the fundamental form of energy that is put in to each device and the output form of energy that is a result.
Your task is to look at six devices and decide what form of energy is the input and which is the output form of energy. Think about your answers carefully before reading ahead to the answers.
- Lawn Mower input form of energy? Output form of energy?
- Computer input form of energy? Output form of energy?
- Sun input form of energy? Output form of energy?
- Tree input form of energy? Output form of energy?
- Gas Furnace input form of energy? Output form of energy?
- Hair Dryer input form of energy? Output form of energy?
| Device | Input form of Energy | Output form of energy | |
