Week Twenty -- Scales

Use some or all of the following materials to build a scale. Then see if you can balance it with 5 pennies on each side.

2 pencils
an eraser
a cup
4 straws
4 paperclips
2 pieces of paper
1 item of your choice
4 inches of string
4 inches of tape

You may use scissors in construction but not the solution.
