Lesson 2:
Electricity is a form of energy. Electricity powers many of the things people use every day. Despite its importance in our daily lives, few people stop to think what life would be like without electricity. But we use electricity to do many jobs for us every day – from lighting, heating, and cooling our homes to powering our televisions and computers. This activity helps illustrate the effect electricity has on our daily lives.
Students will understand the effect electricity has on their daily lives.

Communication, Creativity
Strategic and Extended Thinking
30 minutes
Chalkboard or whiteboard
How important is electricity to your daily life? To the daily life of the school or of the city?
What would be different if there was no electricity?
Are there ways you could use less electricity today?
Lesson 3:
In the video, we learned that a turbine is a giant rotating fan. In this activity, wind is used in place of steam to spin the turbine.
Students will work together to engineer a wind turbine to demonstrate how wind power works.

Read the passage to your students, have them play the Build a Power Plant game, and ask them the critical thinking questions that follow.
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?
What happens when we run out of resources like coal or natural gas?

Read this passage to your students and ask them the discussion questions that follow.
The three most basic units in electricity are voltage, current and resistance. Voltage is measured in volts, current is measured in amps and resistance is measured in ohms.
A neat analogy to help understand these terms is a system of plumbing pipes. The voltage is equivalent to the water pressure, the current is equivalent to the amount of water, and the resistance is like the pipe size.
How do they relate?
Current is equal to the voltage divided by the resistance.
Let’s see how this relationship applies to the plumbing system. Let’s say you have a tank of pressurized water connected to a hose that you are using to water the garden.
What happens if you increase the pressure in the tank? You probably can guess that this makes more water come out of the hose. The same is true of an electrical system: Increasing the voltage will make more current flow.
Let’s say you increase the diameter of the hose and all of the fittings to the tank. You probably guessed that this also makes more water come out of the hose. This is like decreasing the resistance in an electrical system, which increases the current flow.
Electrical power is measured in watts. In an electrical system, power (P) is equal to the voltage multiplied by the current.
The water analogy still applies. Take a hose and point it at a waterwheel like the ones that were used to turn grinding stones in watermills. You can increase the power generated by the waterwheel in two ways. If you increase the pressure of the water coming out of the hose, it hits the waterwheel with a lot more force and the wheel turns faster, generating more power. If you increase the flow rate, the waterwheel turns faster because of the weight of the extra water hitting it.

Using the plumbing analogy, what happens when you lower the pressure (or current)?
Why would some locations need more electricity than others?
Write C=v/r on the board. Ask students what the Current (C) would be if the Volts (v) = 20, and the Ohms (r) = 4.
What would the Volts (v) be if the Current (C) = 50 and the Ohms (r) = 5?
