Name______________________________________________________ Period_______
Unit 1 Review Sheet
1) Technology - practical use of scientific knowledge
2) Organism – a living thing
3) Ecology – study of organisms and how they interact with their environment
Biology – study of living things
Botany- study of plants
4) Give 5 lab safety rules
No long hair or sleeves
Follow directions
Clean up and wash when done
Notify teacher of any accidents or injuries
No open-toed shoes
Be careful with chemicals and fire
Wear eye protection
No horseplay
5) List in order, the steps of the scientific method.
Title, problem, hypothesis, materials, procedure, observations/results, conclusion
6) What two words does a hypothesis usually start with? I think
7) How do you start your conclusion? According to the results
8) Observations – experienced directly
Inferences – conclusion based on your observations
9) Practice converting these: Use KHDUDCM
10) What is the basic unit of volume in the metric system? liter
11) What type of instrument do we use to measure the volume of a liquid?
Graduated cylinder
12) What is the meniscus? Draw a picture here. The curved surface of the liquid in a grad. cylinder
13) What type of instrument do we use to measure the volume of a rectangular solid? Metric ruler
14) How would you find the volume of an irregular shaped solid? Water displacement
15) What is the basic unit of length in the metric system? meter
16) Independent variable – the variable manipulated by the experimenter
17) Dependent variable – the variable being measured in the lab
18) Control – used for comparison
19) What is the purpose of graphing? To show data in picture form
20) State which variable goes on the x-axis and which goes on the y-axis. (independent variable and dependent variable)
x-axis - independent
y-axis - dependent
For the test you should also be ready to:

- 54321 m = 54.321 km
- 42.7 L = 42,700 mL
- .00721 mg = .00000721 g
- 74.0 cm = 740 mm

For the test you should also be ready to:
- Identify the independent and dependent variables from a given scenario.
- Given a graph, be able to tell what relationship it shows
- Answer true/false questions from your notes on Intro to Life Science, Scientific Method, Metric System and Measurement, Volume, and Mass
- Make sure you can do the following:
- Read a graduated cylinder
- Read a metric ruler
- Read a triple-beam balance
- Be able to graph and interpret a graph
- Be able to calculate volume
