Place your penny on the table. Add water to the “LINCOLN” side of the penny, one drop at a time, counting each drop until the water spills over. Do not count the drop that causes the water to spill over. Record your quantitative data/observations in your data table.
Repeat this procedure two more times. Be sure to completely dry the penny and table between trials. Record your data under Trial #2 and Trial #3.
Find the average of your three trials, round your answer to two decimal places, and write the average number of drops on your Test Results chart.
Then write your average on the board under the heading “Actual Average”.
Complete a bar graph of your classroom averages. Use the checklist for graphing rules.
