Know the difference between a scientific law and scientific theory.
Know the 7 steps of the scientific method in order
Know how to write a proper hypothesis (if/then/because)
Know how many variables are in a good experiment
Know the difference between a control and variable experiment
Know how to identify the independent and dependent variables in a hypotheses
Know why a control experiment is done
Know why scientists always repeat their work
Know the types of tools used to measure mass, length and volume.
Know the units and abbreviations of mass, length and volume.
Know how to find the density of an object
Know how to convert in the metric system (example: mm to cm)
Know how to identify significant figures and how many significant figures should be included in an
answer
☐ Be able to describe the difference between precision and accuracy
1. What is the difference between an independent and dependent variable? Write your own hypothesis
and use it as an example.
2.
Why do good experiments have both a control and a variable?
3. Why can’t you change your experiment halfway through if you can see that what you are trying isn’t
going to work?
4. You enter an archery contest with a friend. You win first place for accuracy; she wins first place for
precision. Explain the difference between the awards.
5. Mrs. H. decides to test the effect of Mt. Dew on test taking, so she has the entire class drink a can
before taking a test. Is this a good experiment or not? If not, explain a better experiment.
