1 Charge Transfer uDu Objective: You are a packaging engineer, and you want to build a device that uses static electric charge to pick up those annoying foam peanuts. You plan to build a machine that rubs two materials together to create the charge. You must find and document the best choice of materials.

2 Charge Transfer uDu Materials:
• 4 insulating rods (clear acrylic, hollow polyvinyl chloride, white nylon and maple wood) • 4 cloths (blue silk, gray wool, patterned cotton and polyester felt) • Charge-O-Meter (copper pipe supported on sharp spindle — which means you’re not going to screw around with it)

3 Charge Transfer uDu Methods:
• You will rub the the rods with the cloths to charge them. The design and standardization of the technique is up to YOU. • You will use your Charge-O-Meter to measure how much charge a rod acquires by measuring how strongly they attract each other. YOU have to figure out how to measure strength of attraction. • YOU record your Methods in YOUR notebook.

4 Charge Transfer uDu Results:
Construct a 4 x 4 table that summarizes your results. That is, record the strength of attraction — as measured by YOU — when each rod is rubbed by each cloth. Choose the combination for your peanut picker-upper. AMOUNT of CHARGE Wool Poly Cotton Silk Wood PVC Acrylic Nylon
