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
Read or Listen, Identify Details, Apply Skills

21st Century Skills
Critical Thinking, Collaboration

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.

Lesson 2: Printable PDF
Matter, Heat and Insulation

Objective
Students will use the engineering process to develop an insulated container to minimize the loss of heat energy.

Purpose of Activity
Read or Listen, Identify Details, Apply Skills

21st Century Skills
Critical Thinking, Collaboration

Cognitive Level
Strategic Thinking, Extended Thinking, Skills and Concepts

Class Time
2 hours

Materials

  • Hot water
  • Plastic cup
  • Thermometer
  • Bubble-wrap, wool, cotton and other items to be used for insulation
  • Timers
  • Thermos
  • Laptops or digital device for research
  • Student sheet

Procedure

  1. Show the thermos. Explain that heat energy can be gained or lost due to the cooling or heating effects of the environment. Ask students why they think this thermos can keep something hot on a cold day and have them write ideas down.
  2. Students will conduct an investigation with hot water. The students will try to keep the hot water as warm as possible for the designated time. For the investigation, students will use the cup. They will use other insulating materials to help the container be as effective as possible.
  3. Students then make modifications to the container for a second test.
  4. Students will use the student sheet to record observed temperatures under the evidence portion and will also give reasoning. They will then formulate a claim on how these experiments work and also an explanation.

Critical Thinking Questions

Which insulation worked best to insulate the water?

  • The wool.

What role did heat transfer play in the design of the insulation?

  • Heat transfer was being prevented.

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 electrical safety. There are also helpful links and tips.

example

Born in 1791 to a poor family in England, Michael Faraday was extremely curious, questioning everything. He felt an urgent need to know more. At age 13, he became an errand boy for a bookbinding shop in London. He read every book that he bound, and decided that one day he would write a book of his own. He became interested in the concept of energy, specifically force. Because of his early reading and experiments with the idea of force, he was able to make important discoveries in electricity later in life. He eventually became a famous chemist and physicist.

Faraday built two devices to produce what he called electromagnetic rotation: a continuous circular motion from the magnetic force around a wire. Ten years later, in 1831, he began his great series of experiments in which he discovered electromagnetic induction. These experiments form the basis of modern electromagnetic technology.

In 1831, using his "induction ring," Faraday made one of his greatest discoveries – electromagnetic induction, or the generation of electricity in a wire by means of the electromagnetic effect of a current in another wire. The induction ring was the first electric transformer. In a second series of experiments in September 1831, he discovered magneto-electric induction: the production of a steady electric current. To do this, Faraday attached two wires through a sliding contact to a copper disc. By rotating the disc between the poles of a horseshoe magnet he obtained a continuous direct current. This was the first generator. From his experiments came devices that led to the modern electric motor, generator and transformer.

Faraday continued his electrical experiments. In “In 1832 he proved that static electricity, voltaic electricity produced by a battery, and the electricity induced from a magnet were all the same. He also did significant work in electrochemistry, stating the First and Second Laws of Electrolysis. This laid the basis for electrochemistry, another great modern industry.

Michael Faraday, one of the world's greatest experimental physicists, is known as the father of the electric motor, electric generator, electric transformer and electrolysis. He wrote the "Law of Induction" and is known for the "Faraday Effect."
