Old magazines, chart paper, post-it notes, record player

(Start with a dark, quiet room. Make sure record player is unplugged.) Boys and girls, it's dark in here. I can hardly see. What could we do to see better? (response) John, would you turn on the lights? (response) It's so quiet in here. I wish I could listen to my favorite song. What could we do? (response) Katy, could you turn on the record player? (response) Students, can you find out why it didn't work? (response - it's not plugged in) What should I do? response)

(Plug in record player) Why is it working now? (response) The lights are on and the record player is playing because of the electricity. (Write electricity on the middle of the chart paper) What are some ways in which electricity is used in your home or school? (Write responses on post-it notes and stick them around the word electricity.)

Heater

Vacuum

Stove

Lights

(With students' help, organize the notes into categories such as Entertainment, Work, Comfort, etc.)

Boys and Girls, I want you to look through these magazines and cut out pictures of how people use electricity then we are going to glue them on our electricity chart in the right categories.

Boys and Girls, I want you to draw a picture of how you use electricity. We are going to put all of your pictures into a book and call it "Uses of Electricity".

You can extend this lesson by making a Venn Diagram with your class.

Materials: 3 large circles in different colors (cellophane works best) or you can draw the circles on the chalkboard or posterboard.

Instruction: We have seen the many ways we use electricity. Electricity is used to produce light heat and/or sound. (Label the three circles with these headings.) Use the post-it notes and help children place under the correct headings. (stoves, lamps, radio, furnace, TV, computers)
