Topic: Waste of energy
Description: Start the lesson by discussing the fact that electricity is something that comes to our houses and schools and must be paid for based on how much we use. Allow students to share their existing knowledge about electricity, especially things in their homes that are powered by electricity. Give students 2-3 minutes to list different things that use electricity around their homes and their school. Spend time explaining that some things they use everyday use energy but not necessarily electricity (Batteries, natural gas, etc). Present your questions about the project:
Activities, expectations, objectives, assessment, etc.After listening to teacher and other students input, students will brainstorm about energy used in their home and come up with a list of items
Provide each student with a copy of the attached handout.
Instruct students over the course of 1-2 days, to record when they use an electric appliance, including light switches.
Once students have completed the recording process spend a day in class discussing closure questions.
Ask students if they know how the calculation is done to determine power consumption.
Ask students why electric energy is considered form of energy.
Participate in a conversation in the group about the questions posed by the teacher to present your previous knowledge on Current used in the home.
Ask as many questions as needed for you to comprehend about calculation on energy consumption.
1. How many times each day did you use electricity?
2. Which appliance did you turn on most frequently?
3. Which appliance ran for the longest amount of time? (Highest amount of hours)
4. What are some ways we can help save and conserve energy in our homes?
5. How many of these appliances didn’t exist when your grandparents were children?
6. Do you think they used more or less electricity than you do and why is that important? After Brainstorming, students will correctly attempt to answer all questions
