2.  Make Observations that lead to a question or a problem that needs to be solved.  Propose a hypothesis  Design and perform an experiment. (remember that all experiments are controlled)  Analyze your data and determine whether or not to accept your hypothesis.  If necessary, propose and test a new hypothesis.

3. Problem 1: How strong is a Bess Bug? (Hint -determine the strength of a bess bug)

4.  3 – 4 students per bess bug is maximum within a group  READ the entire lab BEFORE designing your lab.  Assess and inventory the materials that you are provided before designing your experiment.  All experiments have controls.  You will need to make and record measurements and have multiple trials.  You will be graphing your results.

5.  Do you have a complete materials list?  Did you write out and/or provide a labeled drawing for your procedure?  Did you collect data and perform multiple trials ( you can obtain data from other groups)  Did you graph your data?  Did you perform and submit calculations?  Did you Answer the Analysis Questions that are at the end of the lab?

6.  Compare your results with another lab group. ◦ Did both groups use same measurement systems? Why or Why not? ◦ How could you design this lab so that it would be more universal and easier to share results? ◦ How strong was your Bess Bug? ◦ What units of measurement did you use? ◦ Did you design a controlled experiment? Defend your answer. Remember that controlled experiments have only the dependent and independent variables.

7.  Problem 2: Is a Bess Bug stronger than a human? (Hint – you will need to have a means of comparison)

8. Is a Bess Bug stronger than a human?  Explain how you could determine if a bess bug is stronger than a human. (BRIEFLY)  Research the strength of humans and compare your research data to your bess bug collected data.  BRIEFLY explain how you could obtain the strength of a “human” experimentally.
