What are the 3 main stages of the water cycle, and give a short definition of each
Condensation - water vapor collects and forms clouds in the sky
Evaporation - rising temperature turns liquid water on the ground into water vapor in the sky
Precipitation - snow, sleet, rain, hail

______ factors are living things (or once living things) in an ecosystem. An example of this is ________.
______ factors are non-living things in an ecosystem. An example of this is ________.
Biotic Factors - (answers vary: plants, animals, sticks, decaying organisms)
Abiotic Factors - (answers vary: temperature, pressure, rocks, minerals, water, sunlight)

1. __________________ data is based on countable measurements of something
2. __________________ data is information based on something's characteristics
1. Qualitative Data
2. Quantitative Data
200
The variable that is influenced by the Independent Variable, the results of your experiment
Dependent Variable
200
How does a greenhouse gas trap heat? (Think about the shape of the molecules)
Sun rays travel from the sun and hit the earth's surface, reflect off the surface, hit the greenhouse gas molecules where they vibrate, and then get sent and trapped into the earth's atmosphere where they warm the earth

2. Do background research
3. Make a hypothesis
4. Test your hypothesis with experiments and observations
5. Analyze Results with graphs/tables
6. Make a conclusion about your hypothesis
7. Share process or repeat experiement

A variable you run in the experiment first without changing other factors. The purpose of this variable is to compare your results to the "normal"
Control Variable
300
List the three greenhouse gasses we learned about in Unit 1
Carbon Dioxide, Water Vapor, Methane

What is the difference between a pie chart, a line graph, and a bar graph? When would you use each?
Pie chart - shows parts of a whole (best for percentages)
Line graph - change over time (best for long-term data)
Bar graph - shows the amount/quantity for a category (best for comparing groups)
500
How is evidence used in scientific investigations?
Evidence - either observations or data - can be used to support or oppose a hypothesis

Read the following hypotheses and identify both the independent and dependent variables
If you increase the number of cigarettes you smoke, then you will increase your risk for lung cancer.
IV: the number of cigarettes you smoke
DV: risk for lung cancer

How do rising temperatures affect both droughts and floods? Your answer must address both to receive full points
West Coast Droughts: rising temps --> more evaporation --> wind pushes clouds to the east coast --> little to no rainfall in the west coast
East Coast Floods: rising temps --> more evaporation --> wind pushes clouds to the east coast --> too much torrential rainfall

What are the 3 types of symbiosis you learned about in class on Tuesday (when there was a sub), and write a short definition for each.
1. Mutualism - both organisms benefit :) :)
2. Commensalism - One organism benefits, the other one is not harmed or helped :) :/
3. Parasitism - One organism is harmed while the other benefits :) :(

What does C.E.R. stand for, and define the C., E., and R.
Claim - a statement that summarizes the results of an experiment or phenomena
Evidence - data/graphs/observations/proof that support the claim
Reasoning - justification sentences that link the evidence to the claim, tying in previous knowledge to help explain your point
