PROBLEM: How many drops of water will fit onto the “Lincoln” side of a penny?
Write your hypothesis in your comp book.
PREDICTION (Hypothesis): I predict that ____ drops of water will fit on the head side of a penny.
Copy the chart into your notebook.
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.
Write conclusion. Remember it should state whether your hypothesis was supported by the data or not.
Answer the conclusion questions. Use complete sentences!
Conclusion:
Based on the data collected, it was found that an average of ____ drops of water fit on the "Lincoln" side of a penny. This supports/rejects the hypothesis that _____ drops of water would fit.
Conclusion Questions:
1. What was your average number of drops?
2. How does your average compare to your hypothesis?
3. Do you think the number of drops would be the same for all pennies? Why or why not?
4. What factors do you think may have influenced the number of drops that fit on the penny?
I cannot perform the experiment as I am an AI and do not have the capability to physically interact with objects. However, I can assist you with the steps you need to follow and help you answer any questions you may have.
Here are the steps you can follow to conduct the experiment:
Materials needed:
- Penny
- Water dropper
- Table or flat surface
- Paper towels or cloth for drying
Procedure:
1. Start by placing the penny on the table with the "LINCOLN" side facing up.
2. Using the water dropper, add water to the "LINCOLN" side of the penny, one drop at a time.
3. Count the number of drops you add until the water spills over the edge of the penny. Do not count the drop that causes the spillage.
4. Record your quantitative data and observations in a data table. The table should include trial number, number of drops, and any additional notes or observations.
5. Repeat the procedure two more times, making sure to completely dry the penny and the table between trials.
6. Record the data from each trial under Trial #2 and Trial #3 in your data table.
7. Calculate the average of your three trials by adding up the total number of drops from all trials and dividing it by 3.
8. Round your average answer to two decimal places and record the average number of drops on your Test Results chart.
9. Write the average on the board under the heading "Actual Average."
10. Create a bar graph of the classroom averages, using the checklist for graphing rules.
11. Write your conclusion, stating whether your hypothesis was supported by the data or not. Provide reasoning and evidence to support your conclusion.
12. Answer the conclusion questions using complete sentences.
Please note that steps 9 and 10 can be done after collecting data from all the participants in the classroom and obtaining their individual averages.
