Background Information

A Hand Crank Flashlight is purchased online to show how energy is transferred in the system. To better understand how the hand crank system works the flashlight is taken apart (figure below). To reverse engineer this flashlight and build this mechanism the materials (A-F) below must be identified and purchased.

Investigation Plan - Materials Testing

In addition to closely observing the six materials below (A-F) the following tests were performed on the materials: lightbulb test, paperclip test, magnet test and water test.

What is the purpose of the investigation? (Use hint for sentence starter)

Now that you have collected data from the pictures and video, you have decided that more information is needed.
What two more tests could you do to learn more about the materials’ physical and chemical properties? (Use hint for sentence starter)

Why would these two tests answered in question 8 specifically be helpful in the identification of these materials? (Use hint for sentence starter)

After doing the two tests and collecting data, what would you do next to figure out what each material in the flashlight is? (Use hint for sentence starter)
