Harnessing the Sun’s Energy with Solar Panels

Difficulty: Grade 6-8
Time: 45-60 mins
Categories: Renewable Energy

In this lesson, students will learn how energy from the sun can be harnessed with solar panels to create a renewable source of energy. In the ‘Take Action’ section of this lesson, students will build a solar panel prototype that can sense and track the position of the sun in order to find the most optimal light source for power generation.

Learning Goals

  • Describe how solar panels work
  • List the benefits of solar power over non-renewable energy sources
  • Build solar panel prototype that:
    • detects light level in the environment
    • moves throughout the day to ensure maximum light exposure and efficiency

Prerequisites

Students should have a basic understanding of how the Earth’s rotation around its axis impacts the apparent movement of the sun from east to west.

Materials

Big Idea (15 minutes)

Learn how solar panels work and the benefits they have over alternative methods of electricity generation.

Take Action (45 minutes)

Build your own solar panel prototype with the Climate Action Kit!

We've provided 3 ways students may build the project to support scaffolding and differentiation in your classroom: 'Use', 'Modify', and 'Create'.*

Activity Description
Use

Students will follow a step-by-step tutorial to build & use their solar panel prototype. The goal is to help them develop a better understanding of its features.

Success Criteria

I can:

  • build a solar panel prototype with the Climate Action Kit
  • use the MakeCode simulators to explain how the solar sensor and positional servo motor work
  • describe how to use events to change the position of my solar panels at different times of day
  • decide where to put a solar panel on my building based on my understanding of how the sun appears to move across the sky

Tutorial
Final Code
Modify

Students will follow a step-by-step tutorial to build their solar panel prototype. After this, they will modify the code and complete a basic challenge to demonstrate their understanding.

Success Criteria

I can:

  • build a solar panel prototype with the Climate Action Kit
  • predict how small changes to my solar panel’s code might impact its function
  • explain how to use conditional statements, variables, and math operators to make my solar panels move automatically to get the most sunlight during the day
  • write my own conditional statement to control how far my solar panel can move

Tutorial
Final Code
Create

Students will work in small groups to research modern solar panels and design a prototype with the Climate Action Kit.

Success Criteria

I can build a solar panel prototype with the Climate Action Kit that can:

  • sense the level of sunlight in the environment
  • change positions to ensure maximum sunlight exposure

and uses at least:

  • one sensor
  • one servo motor

  • Justify a hypothetical installation location for the solar panel (Use)

Observations

  • Methodically test and debug their code to ensure it functions as intended (Modify, Create)

Products

  • Add comments to the code to demonstrate their understanding of each block (Use, Modify, Create)
