Why did each group test the amount of drops of water a penny could hold before changing their variable?

• It provides more data to include in a lab report

• It ensures that the hypothesis will be correct

• It adds an independent variable to the experiment.

• It is the control and serves as the basis for comparison

Group 1 found food coloring affects the amount of drops a penny holds.  Group 2 found that food coloring does not.  What should they do?

• Ignore Group 2

• Conduct it again with quarters

• They should repeat the experiment again and compare results

• Conclude that food coloring has no effect
