Positives
The lesson is personalized to the students' community, which will make it more engaging and relevant.
This lesson ties closely with the following lesson in the unit, but it can also be used as a standalone lesson if desired.
Additional Prerequisites
This is lesson 1 of 5 in our 6-8th grade Renewable Energy Algebra unit.
Students should know kWh refers to Kilowatt-hour. This interactive map about the carbon intensity of electricity by country measured in kWh can support students with better visualizing the unit.
Students should understand that kilo means 1,000, so a kilowatt is 1,000 watts. This reading can help students build background knowledge on electric power and its units of measure.
Differentiation
Teachers can have students work with a partner on the calculations in the Investigate section and purposefully group students based on skill level.
Teachers can work with small groups of students who may need additional assistance with the calculations.
Teachers can limit the number of questions students complete. The questions get progressively more difficult.
Some questions have the same setup but use different numbers. If necessary, some could be taken out to save time (questions 1-4 and questions 5-7).
This lesson lets students analyze peak sun hours needed to generate electricity from a solar panel. The equation used in the calculation is appropriate, and students would be able to calculate their electricity footprint in real-time. All accompanying materials, case studies, and activities contained in this lesson are well-sourced. Accordingly, this lesson has passed our science credibility and is recommended for teaching.
