Earth science HW

Finish min lab final draft following standard OHS lab format.

1.question/problem (often based on observation)
2.hypothesis (educated guess that answers your Q)
3.test (experimental concepts)
4.materials (everything used in experiment)
5.procedures (recipe of experiment with diagrams)
6.data (data table and observations of data collection)
7.analysis (graph of data, related math, and occasional questions provided by teacher)
8.conclusion (What happened?  Did you answer question? Did data support or refute hypothesis? Why? How did error influence your results? Next step/societal implications)
 
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 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
results?
