Lesson 1:

Lesson 1: Electricity Every Day  

Introduction

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.

Cognitive Level

Strategic and Extended Thinking

Class Time

30 minutes

Materials

Chalkboard or whiteboard

Procedure

  • Ask the students to identify things in the classroom that use electricity. Write these answers on the board. Have them continue to identify things at home that also use electricity.
  • The students will write (or draw a picture) about the things they do every day that use electricity. (Examples: My alarm clock woke me up, I turned on the lamps, I dried my hair with a hair dryer, made toast, etc.)
  • Present the stories to the class.

How important is electricity to your daily life? To the daily life of the school or of the city?

  • Without electricity we would not be able to use computers or lights at school. Businesses could not run and everyday life would be impossible.

What would be different if there was no electricity?

  • None of our appliances would work. Businesses and schools could not operate.

Are there ways you could use less electricity today?

  • Turn off lights and appliances. Replace old lightbulbs with energy-efficient ones. Use smart appliances and programmable thermostats.

Lesson 2:

Who Turned Out the Lights?

Objective
Students will use the engineering process to build a solar oven out of a pizza box.

Purpose of Activity

Cognitive Level
Strategic Thinking, Extended Thinking, Skills and Concepts

Class Time
1 hour

Materials

  • One pizza box from a local pizza delivery store
  • Newspapers
  • Tape
  • Scissors
  • Black construction paper
  • Clear plastic wrap
  • Aluminum foil
  • One piece of notebook paper
  • One pencil or pen
  • One ruler, wooden dowel or stick
  • Edible treat, such as a cookie or s’more

Procedure

  1. Make sure the pizza box is folded into its box shape and closed.
  2. Place the piece of notebook paper in the center of the lid of the box and trace its outline on the lid. Put the piece of paper aside.
  3. Carefully cut the two long edges and one of the short edges of the rectangle that you just traced on the lid of the box forming a flap of cardboard.
  4. Gently fold the flap back along the uncut edge to form a crease.
  5. Wrap the underside (inside) face of this flap with aluminum foil. Tape it on the other side so that the foil is held firmly. Try to keep the tape from showing on the foil side of the flap. The foil will help to reflect the sunlight into the box.
  6. Open the box and place a piece of black construction paper in so it fits the bottom of the box. This will help to absorb the sun's heat.
  7. Roll up some newspaper and fit it around the inside edges of the box. This is the insulation that helps hold in the sun's heat. It should be about 1 to 1 1/2 inches thick. Use tape to hold the newspaper in place, but only tape it to the bottom of the box, not the lid.
  8. Open the box again and cut two pieces of plastic wrap an inch larger than the flap opening on the box top. Open the box again and on the inside of the box lid, tape one piece of plastic wrap so that it covers the hole in the lid. After taping one side, BE SURE TO PULL THE PLASTIC WRAP TIGHT, and tape down all four sides so the plastic is sealed against the cardboard. Then close the box and tape the other piece of plastic wrap to the top of the flap opening. Again, be sure the plastic wrap is tight and tape down all four edges to form a seal. This creates a layer of air as insulation that helps keep the sun's heat in the box.
  9. On a sunny day, pick a treat to warm up and carry it and the box outside to a sunny spot. If it's cold outside, put a towel or blanket under the box so the bottom doesn't get cold. Open the box, put the treat in the center and close the box. Now open the flap and turn the box so the foil is facing the sun. The shadow of the flap should go straight back from the back of the box. Move the flap up and down and note how it reflects the sunlight. Use a dowel, ruler or stick to prop up the flap so that it bounces the sunlight into the box.
  10. Wait about thirty minutes for the box to warm up in the sun. Then enjoy your warmed-up treat!

Critical Thinking Questions

How can we use solar power to generate electricity?

  • Two ways. One – solar panels can turn sunlight directly into electricity. Two – solar reflectors, like this oven, can be used to heat up molten salt. The molten salt can then be used to boil water to create steam which can spin a turbine and generate electricity.

What role did the insulation play in this oven?

  • The insulation prevented a heat transfer from the oven and helped keep it warm.

EXPANDED INFORMATION & ADDITIONAL RESOURCES  

You’ve covered the basics of electrical safety. If you really want to dig deep with your class, explore the expanded information and additional resources below.

These materials provide even more insight into the history, science, usage and importance of electricity. There are also helpful links and tips for safety and conservation in your community.

Expanded Information 1:

Expanded Info: How We Generate Electricity

Introduction

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.

Expanded Info: Watt’s Up with Electrical Terms?

Introduction

Read this passage to your students and ask them the discussion questions that follow.

Read to your class

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.

Source: HowStuffWorks.com

Using the plumbing analogy, what happens when you lower the pressure (or current)?

  • The water doesn’t flow as fast.

Why would some locations need more electricity than others?

  • Larger buildings typically use more electricity than smaller ones. Therefore, a school uses more energy than a home.

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.

  • Answer = 5 Amps

What would the Volts (v) be if the Current (C) = 50 and the Ohms (r) = 5?

  • Answer = 250 Volts

Laws of energy

To scientists, conservation of energy does not mean saving energy. Instead, the law of conservation of energy says that energy is neither created nor destroyed. When people use energy, it doesn't disappear. Energy changes from one form of energy into another form of energy.

A car engine burns gasoline, converting the chemical energy in gasoline into mechanical energy. Solar photovoltaic cells change radiant energy from the sun into electrical energy. Energy changes form, but the total amount of energy in the universe stays the same.

Energy efficiency is the amount of useful energy obtained from a system. A perfectly energy-efficient machine would convert all of the energy put into the machine to useful work. In reality, converting one form of energy into another form of energy always involves a conversion into usable and unusable forms of energy.

Most energy transformations are not efficient. The human body is a good example. The human body is like a machine, and the fuel it requires is food. Food gives a person energy to move, breathe and think. However, the human body isn't very efficient at converting food into useful work. The human body is less than 5% efficient most of the time. The rest of the energy is converted to heat, which may or may not be useful, depending on how cool or warm a person wants to be.
