Notes for teachers

The goal is for students to learn about the pros and cons of installing solar panels on residential rooftops.

While great for the environment and energy cost saving, the cost can be prohibitive for many homeowners

Resident who rent a house or live in apartments do not typically have options for cost saving solar energy programs.

A Solar Equity Gap exists in America between those who can ‘afford to save’ money and those who cannot access saving via solar energy

Az H.S. Standards

HS+E.E1U3.9 Construct an explanation, based on evidence, for how the availability of natural resources, occurrence of natural hazards, and changes in climate have influenced human activity.

HS+E.E1U3.10 Ask questions, define problems, and evaluate a solution to a complex problem, based on prioritized criteria and tradeoffs, that account for a range of constraints, including cost, safety, reliability, and aesthetics, as well as possible social, cultural, and environmental impacts

HS.P4U3.9

Engage in argument from evidence regarding the ethical, social, economic, and/or political benefits and liabilities of energy usage and transfer.

Science & Engineering Practices

Agenda

This lesson ideally takes two 50 minute class periods (or can be assigned as homework)

Students can discuss their final takeaways in small group or whole class discussions

7 of 10

Intro/Driving Question/Opening

What are the advantages of installing solar panels on the rooftop of a home?

What are the disadvantages of installing solar panels?

How many of you know someone who has solar panels on their roof?

What is the startup cost for installing solar panels?

Hands-on Activity Instructions

  • Group size: Individual assignment or small groups of 2-3
  • Introduce the activity with the discussion questions on slide 7
  • Students will then work through the research activity in order to

collect data, answer questions, and make their final argument.

Assessment

Students write a letter to a local government entity discussing the solar equity gap and potential solutions,such as subsidizing the cost, group farms, policy shifts or economic programs.

Students should be able to clearly describe the solar equity gap and give numeric examples of startup costs using the Google Sunroof activity. Solutions do not need to be well vetted, as many students will not have a depth of understanding of government policymaking.

Differentiation

Pair student together based on ability or prior knowledge to the subject

Part 1 and Part 2 can be separated and done independently.

This activity can be lead in a structured manner (as written) or can be picked apart for what is desired.
