Solving Problems in Science and Experimental
DesignIntroduction to Biology
MHS Biology Department
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.
What are the steps that scientists take to solve problems or answer questions?
Problem 1: How strong is a Bess Bug? (Hint -determine the strength of a bess bug)
Here is you turn to solve a problem using the Scientific Method
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.
Guidelines
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?
Part 1: Check Your Lab – Is it Complete?
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.
Follow Up Questions
Problem 2: Is a Bess Bug stronger than a human? (Hint – you will need to have a means of comparison)
Follow Up Brain Teaser!
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.
