Comparing Light Bulbs
Energy Efficiency and Conservation
In this exercise, students will use a light to demonstrate the difference between being energy-efficient and energy-wasteful, and learn what energy efficiency means. After the lesson, they should be able to discuss the following:
- How does using less energy help our environment?
- Do compact fluorescent light bulbs and standard light bulbs create the same amount of light?
- How do you know if one light bulb is more efficient than another light bulb?
