The sketches focus on the following educational points:

  • How we measure energy use
  • How energy is wasted
  • How we conserve energy
  • What renewable resources are

After watching the performance use the provided digital materials to expand upon the educational content of the program.


Your students can enhance what they learn from the program with these fun, hands-on lessons and experiments. These lessons can be done in the classroom or easily adapted for students to do at home with their families.

They’re a fun and educational way for students to learn with family members. The materials needed for these lessons are basic supplies that most people have at home. Follow up with your students to make sure they enjoyed and learned from these activities.

Lesson 1:

The Solar Power Challenge

Students will identify photovoltaic solar power as a source of energy. Students will explain what happens when a photovoltaic cell is shaded. Students will understand why we can’t rely solely on this resource for energy.

Class Time
4 class periods of 45 – 60 mins

  • Day 1: Introduction and Research
  • Day 2: Building the Prototype
  • Day 3: Testing Prototype and Redesign
  • Day 4: Testing of Redesign and Interpretation

Materials listed are enough for one group of 3-4 students.

Divide the students into groups of three or four. Allow students to design their houses based on the templates. Make sure you have stiff paper that will be able to hold the weight of the solar panel. The students will also need a square of poster board to place their house on as a base.

Day one: Introduction and Research
Have students discuss their knowledge of solar panels – where they have seen them and how they work. After the discussion, let the students come up with some questions they may need to know before they create a house that will hold a solar panel. Have them write down their questions. As a class, look at the questions the groups came up with.

Research: On the student worksheet, there are links that the students can click on and watch to learn how solar panels work and how they create energy. Students will need to take notes. Have the students work quietly on their own notes and designs.

Bring the students together in their groups. Ask them if there is something they would add or change to their model. As a group, determine which house design will provide the best solar solution. Where should the solar panels go?

Have the groups use their research to create a model that will meet the criteria and constraints. Make sure they realize that they only have a limited time to build their prototype. The students will also need to have a look at what supplies are available for use. Groups must make a list of supplies. They will also need to have a detailed model with notes of the height of the house, the angle of the roof, where they are putting the solar panel and their prediction on how many watts of energy they will get.

Note: Some students may want to place their solar panel on the ground. If so, make sure they indicate at what angle the panel will be set.

Day two: Building your Prototype
Students build their prototypes.

Day three: Testing, Analyzing and Redesign
Teacher prep: Set up an area outside where the students can test their prototypes. Make sure that each group has access to the voltmeters. The students will need ten minutes to test their prototypes at least three times throughout the day. Suggested times would be first thing in the morning, around lunchtime and at the end of the day. The students will need time to redesign their prototypes and retest them.

Student groups can test their prototype, writing down the amount of energy they have created using solar energy. They will record the volts on the voltmeter. They will also need to record any observations they may see (example: angle is off, roof is too steep, roof is too weak, etc.).

Once the group has tested their prototype, the students need to answer the analysis questions. Students will then get an opportunity to redesign and update their prototype. Explain that this is not a time to start over from the beginning. This is the time to look at the problems and use different ideas to come up with a solution. Allow time for the students to make the changes to their prototype and test again. Record their data and observations on data table.

Day four: Testing Redesign and Analyzing Data
Allow students to test their redesigns and analyze the data.

Critical Thinking Questions

What are some constraints to homeowners that wish to use solar energy?

  • Cost of solar panels, amount of electricity the panels can produce, number of days of adequate sunlight, the size of the homeowner’s roof.

Why is solar energy attractive to homeowners?

  • The energy source is free, solar energy produces little or no emissions, current energy sources do produce emissions, solar energy costs less than other sources.

Lesson 2:

Who Turned Out the Lights?

Students will witness a simple phenomenon where the classroom lights are out and all electronic devices/equipment are off. They will ask questions about how this would affect their lives and how it is affecting them right now. Students will build a simple circuit with a battery and light.

Class Time
50 minutes


  • Classroom with electric lights
  • Circuit building kit here
  • Double AA batteries (1 per student group)
  • Student sheet


  1. Turn all of the lights off in the classroom along with all other electronic devices (except for computer carts). Students will come into a dark room. Tell them that we cannot have the lights on today because we are pretending there is no electricity in the room.
  2. Ask students for questions that they have about why the room is dark and what it might mean. Students record them on their student sheet. (Hand them the student sheet upon entering the classroom.)
  3. Students will plan and build a simple light circuit using the circuit building kit and will investigate how energy is being transferred from a battery to a wire and can be used to create light.

Critical Thinking Questions

What must happen to make the circuit work to turn on the lightbulb?

  • The wires must be attached to the top and bottom of the battery. The wires must be attached to the lightbulb.

What are ways we can save energy?

  • Turn off lights when we are not using them. Use energy-efficient lightbulbs, etc.

Expanded Info: How We Generate Electricity


Read the passage to your students, have them play the Build a Power Plant game, and ask them the critical thinking questions that follow.

Read to your class

We use electricity every day to power our TVs, computers, video games, lamps and about a million other things. But where does electricity come from, and how does it get into those funny looking holes in the wall?

Let’s go backwards. The outlets in your wall are connected to a series of wires that lead to utility poles outside of your house or apartment building. These wires then lead to transformers or substations, which, in turn, lead to a power plant. It’s in the power plant that the electricity is created.

In the 1800s, scientists discovered that when a magnet is dragged across a series of copper wires, it creates a field of electricity. The problem is, in order to keep your lightbulb lit, there has to be a constant current of electricity flowing through it, which means the magnet has to be continually moving. To solve this problem, the magnets in the power plant are surrounded by wires on all sides. So if the magnets spin in a circle, they create a nonstop current.

But how do we keep that magnet spinning? One way is to attach it to a turbine. A turbine is like a giant fan. Imagine a child’s pinwheel. If the magnet were attached to that pinwheel, then it would spin any time the child blew on it. In the power plant, the pinwheel-like turbine isn’t spun by a child with amazing lung capacity, but instead with steam. By focusing steam through smaller and smaller pipes, it becomes so powerful it can spin the turbine with great ease.

All that steam comes from boiling large amounts of water. The more water we boil, the more steam we produce, which takes us to resources. All of that water has to boil somehow, and we make that happen by burning resources like coal, oil and natural gas. The more electricity we make, the more resources it takes to make it. And because there’s only so much coal, oil and natural gas in the world, it’s more important than ever that we conserve, or save, electricity wherever possible.

What is another way we can spin the turbine?

  • We can put a turbine in a river. This is how hydroelectric dams work.
  • We can also use the wind to spin a turbine in a windmill.

What happens when we run out of resources like coal or natural gas?

  • They’re gone. We will have to use renewable resources like wind, solar or hydro.

Solar Power

The surface of the Sun has a temperature of about 5,800 Kelvin (about 5,500 degrees Celsius, or about 10,000 degrees Fahrenheit). At that temperature, most of the energy the Sun radiates is visible and near-infrared light. At Earth’s average distance from the Sun (about 150 million kilometers), the average intensity of solar energy reaching the top of the atmosphere directly facing the Sun is about 1,360 watts per square meter, according to measurements made by the most recent NASA satellite missions. This amount of power is known as the total solar irradiance.

A watt is a measurement of power, or the amount of energy that something generates or uses over time. How much power is 1,360 watts? An incandescent lightbulb uses anywhere from 40 to 100 watts. A microwave uses about 1,000 watts. If, for just one hour, you could capture and re-use all the solar energy arriving over a single square meter at the top of the atmosphere directly facing the Sun, you would have enough to run a refrigerator all day.

The total solar irradiance is the maximum possible power that the Sun can deliver to a planet at Earth’s average distance from the Sun; basic geometry limits the actual solar energy intercepted by Earth. Only half the Earth is ever lit by the Sun at one time, which halves the total solar irradiance.

In addition, the total solar irradiance is the maximum power the Sun can deliver to a surface that is perpendicular to the path of incoming light. Because the Earth is a sphere, only areas near the equator at midday come close to being perpendicular to the path of incoming light. Everywhere else, the light comes in at an angle. The progressive decrease in the angle of solar illumination with increasing latitude reduces the average solar irradiance by an additional one-half.

Averaged over the entire planet, the amount of sunlight arriving at the top of Earth’s atmosphere is only one-fourth of the total solar irradiance, or approximately 340 watts per square meter.
