  6. Choice of metals • The choice of metals used in a battery depends on both the voltage desired and how quickly the current will drain from the battery.

  7. Amount of Energy • The amount of energy a battery can supply also depends on the number of electrons produced per second in the reaction.

  8. Introduction pg. D-64 • Glossary: • 1. Battery-electrons combined together to produce electricity • 2. Electrolyte- the material that makes the liquid electrically conductive.

  9. Materials pg. • Safety: Write in your own words • Procedure: • Part A: Testing the Motor • Complete steps #1-6 • Procedure Captains: make sure you follow all steps • Getter: Get materials & record data • Spokesperson: conduct experiment • Facilitator: Make sure everyone is on task and conduct experiment

  10. Part A: Testing the Motor/Part B:-----

  11. Part B:The Effects of Different Metals • Answer the 5 questions from Step #7 • What materials are you going to use? • Think about what metals will you use, you already used magnesium and copper. • How will you use them? Where will you place them on the wet cell? • Add the metals to the data table • Raise your hand once complete to approve to begin!

  12. Part C: Other Effects • Create data table-make sure you have a title • Complete Step #11 What happens to the direction the shaft turns when you reverse the connections? • Use zinc & copper- record what happens • What happens to the motor when you remove both metal strips from the electrolyte? • Record observation • Create a conclusion of what happened in the experiment
