Unit 4D, Magnetism and Electricity Unit Project: An Inventor's Fair Has the work of inventors like Thomas Edison or Benjamin Franklin ever intrigued you? Here is your chance to follow in their footsteps. Build your very own inventions using magnetism and electricity. Then display them at your class's Inventor's Fair.   Project Link 1 (Chapter 1, page D9) With other students, brainstorm to get ideas for a magic trick that uses magnets or electricity. Think about a trick that works because the force of a magnet can be “felt” through various materials. Make a drawing and then build a model of your magic trick. Include instructions so that others can build their own models.

Invent a way to use the opening and closing of circuits in your quiz board. Decide how and where to place dry cells, wires, light bulbs, and a buzzer. Decide what kinds of questions you can ask and how you'll arrange them on the board. Be creative!
