Earth science reading and lab

Read skill handbook on practicing scientific method, pgs. 928 - 933, in the Glencoe Earth science book.  Take Cornell Notes.

Question:  How many drops of water can a penny hold?

Hypothesis:  What is your educated guess to answer the question?  You may compare a penny next to a single drop to help you with this.

Materials:  Record every item used for data collection

Procedures: Record Step by step directions of how you used each material listed in your experiment to find your answer, include diagrams that help illustrate complex  procedures. Final  procedures should be more complex than those listed in your RD.

Data table:  Have room to include ten trials of data collection.  Yes, do the experiment ten times, (5 trails per person) make sure everyone in your group has an opportunity to collect data by doing the experiment.

Analysis:    Show an example of you calculated the average  # of drops for the trials you did. Create a data table showing the average drop # for your group. Make a bar graph of your trails and the average # of drops.

Conclusion:         This should be in para graph form and not just answers to the following questions

Did you answer the question?   Do your results compare to the other tables?  Explain.  How might error have occurred in your experiment?  How can you redo your experiment to attain more accurate results?

Bonus Points:  if you finish early, you may earn bonus points for conducting a next step to this experiment.  You are limited to the materials provided or on your person & you must make another lab write up.  You may also include a graph of your data for e.c.
