Midterm Study Guide
Survey of Life
1. All living things share the following characteristics: a. All living things are composed of one or more cells b. Organisms are organized
c. Organisms use and create energy for growth
d. Organisms grow and develop by cell division
e. Organisms respond to stimuli from environment & from within the organism itself to maintain homeostasis f. Organisms reproduce
g. All living things adapt and evolve
2. Label the parts of the microscope

3. What does Nature of Science mean?
How science is a unique way of knowing about the natural world 4. What is a body of knowledge?
Facts, definitions, concept, theories, laws
5. What is a way of know?
Change over time, based on evidence, creativity is important 6. What is a set of methods/processes?
Observe, measuring, inferring, predicting, classifying, hypothesizing, experimenting, analyzing 7. Define observation
A data collecting strategy, qualitative—using the five senses, quantitative—counting or using numeric data 8. Define inference
An attempt to explain or interpret observations by using what you observe and/or previous knowledge and experiences, observations what you see infers what you think you see 9. How do you design an experiment?

h. Question
i. Gather information: preliminary observation & scientific literature j. Form a hypothesis
k. Preform a controlled experiment: only one variable is changed l. Record and analyze data: observe qualitative & quantitative data m. Draw conclusions
n. Share conclusions: publish scientific literature & repeated investigation 10. Define hypothesis
A prediction about the relationship between the variables that can be tested If the IV is _________ (describe how you changed it), then the DV will ___________ (describe the change) 11. Variables:

Independent Variable (IV)
The variable that is purposefully changed by the experimenter Dependent Variable (DV)
The variable that responds to what happens with the independent variable Constants (C)
All variables that remain the same *Also known as Controlled variables* 12. Parts of a Design Diagram:
Title
A statement relating the IV to the DV in the experiment
Control
The standard for comparing experimental effects
Repeated Trials
The number of experimental repetitions, objects or organisms tested at each IV level 13. What is the instrument that measures mass?
Triple Beam Balance
14. What is the instrument used in the laboratory that measures the volume of liquid? Graduated cylinder
15. What tool is used to measure short lengths?
Ruler
16. What tool is used to measure the temperature in the laboratory? Thermometer
17. Metric unit for length
Meter
18. Amount of matter that an object contains
Mass
19. Metric unit for mass
Gram
20. Instrument used to measure volume
Graduated cylinder
21. 1 meter= 100?
Centimeters
22. Metric unit for liquid volume
Liter
23. Measure of the force of gravity acting on an object
Weight
24. Metric unit for temperature
Celsius
25. 1 liter= 1,000?
Milliliter
26. 1,000 grams= 1?
Kilogram
27. Instrument used to measure length
Meter stick
28. Dip in the surface of liquid in a graduated cylinder
Meniscus
29. Amount of space that something occupies
Volume
30. Define Facts
Data scientists use in confirming or disputing their ideas
-Valid observations can be viewed as facts
-Facts engender a high degree of confidence and correspond around scientists
*Even facts can change with new data*
31. Define Theory
Structures of ideas used to explain and interpret facts
-not simply hunches they are based upon data...
