1. What is a hypothesis and how should someone go about formulating an educated hypothesis?
2. What should always be true of your research?
3. Is a hypothesis always supported by experimental results?
4. (T/F) Valuable information can be gained even if the hypothesis is not supported by the results.
5. Can results from an experiment prove a hypothesis is correct? Why or why not?
6. How does a hypothesis become a scientific law or principle?
7. Which of the following data measurements is most accurate & explain why: 4, 4 cm, 4.2 cm, or 4.25 cm.
8. Compare and contrast precision and accuracy.
9. List the steps to the scientific method in order.
10. Compare independent and dependent variable with regards to a scientific investigation.
11. Scientific investigations are designed to answer a question about the relationship between two variables
in a predicted “cause-effect relationship”. Of the two variables the (independent or dependent) variable
is the “cause” and the (independent or dependent) variable is the “effect” in an experiment.
12. What are controlled variables and why are they essential in a scientific investigation?
Biology Standard 1
13. Which variable in an experiment (independent or dependent) is plotted on the “X” or horizontal axis?
14. Which variable in an experiment (independent or dependent) is plotted on the “Y” or vertical axis?
15. Name and explain when to use the 3 main types of graphs.
16. (T/F) The shape of a graph can show the relationship between the variables in the hypothesis.
17. In the graph above, answer the following questions:
a) What is the independent variable?
b) What is the dependent variable?
c) What is the unit of measure for the independent variable?
d) What is the unit of measure for the dependent variable?
e) What is the frequency when the wavelength is 100m?
f) What can you conclude about frequency when wavelength increases?

18. (Direct, inverse) variation occurs when the independent and dependent variables either both increase or
both decrease.
 Draw a line graph to represent this type of variation.
(Direct, inverse) variation occurs when one variable increases while the other variable decreases.
 Draw a line graph to represent this type of variation.
19. Arrange the following units in order from largest to smallest: decigram, hectogram, milligram,
kilogram, centigram, gram, and dekagram.

25. Compare and contrast model and scientific model.
26. Compare and contrast scientific law and scientific theory.
27. Technological designs are produced by the application of scientific knowledge to meet specific
needs of humans. Four stages of technological design: (1) problem identification, (2) solution
design (cost, time, material), (3) implementation, (4) evaluation.
28. What is science?
29. How does science relate to technology?
30. Know ALL safety symbols and safety procedures.
