ES: Volume of a Drop Final


Instructions:  DO NOT WRITE ON THIS HAND OUT!  You and your tablemates will be practicing the steps of the scientific method, conducting an experiment and writing-up a lab. 

·       On a separate sheet of paper write the names of the members of your table that actively help with all parts of the mini-lab; this will be your lab write-up.

·       Write out the question I gave you below, include the label Question:

·       Write our Hypothesis: and then your educated guess to answer the question.  Remember to discuss with your tablemates about how to make an educated guess then record the hypothesis on your lab write-up.

·       Continue writing the label for each step (Q, H, T, M, P, D, A, & C) and following my hints for each step.


Question:  How much space (volume) does a drop of water take up?

Hypothesis:  What is your educated guess to answer the question? Compare 1 drop to 1 mL of water.

Materials:  Every item used for data collection

Procedures: Step by step directions of your experiment that include diagrams that help illustrate your procedures

Data table:  Have room to include ten trials, Yes, do the experiment ten times, make sure everyone in your group has an opportunity to collect data by doing the experiment.

Analysis:    Show an example of how calculated the volume of a drop, in mL. Also show an example of how calculated the average volume of a drop, in mL, for the trials you did. Create a data table and Bar graph showing the average drop # for all other groups in the class.

Conclusion:         Restate your hypothesis. Did you answer the question?
                    How do your results compare to the other tables?  Explain.
How might error have occurred in your experiment?  What affect might it have had?  How can you redo your experiment to attain more accurate

Bonus Points:  if you finish both mini-labs early, you may earn bonus points for applying your data from this lab to the drops on a penny lab to find the ave. volume of the bubble of water that formed on the penny.  Explain what you did and show the calculation.
