This disaster occurred during the Great Depression and was a result of poor farming practices
What is the Dust Bowl?
100
This is a testable explanation. It must include the effect that the independent variable has on the dependent variable.
What is a hypothesis?
100
This region saw approx. 2x more annual average grain increase since 1961-63?
What is Asia?
100
This is the formula for percent change
What is (New-Old) / Old x 100?
100
This is an example of Tragedy of the Commons
Any answer that has to do with public resources being overused for individual gain is correct.
Private lands do not count!!!!

This was the worst nuclear disaster in the world and the location to this day is still uninhabited by people.
What is Chernobyl?
200
This is a group in an experiment without the independent variable added.
What is the control group?
200
This Canadian city had the highest ecological footprint per Capita
What is Calgary?
Bonus: Hypothesize why Calgary and Edmonton have higher ecofootprints than the other cities.

This is the method you would use to calculate percent change in the amount of runoff in urban areas vs forested areas. (Give me the numbers!)
1. Forested areas = 10% of rain becomes runoff
2. Urban areas = 55% of rain becomes runoff
What is (55-8)/8 x 100

Typically in an ecosystem, this is what would happen to prey if you increase the number of predators in the area.
What is "prey will decrease?"
300
This disaster was caused by the Hooker Chemical Company. They dumped chemicals in a landfill where a school and neighborhood was built, causing exposure to carcinogens.
What is the Love Canal?
(I almost typed Love Island oops 🤧)
300
A local citizen science group collected water samples once a week between the hours of 7 am and 9 am in the same location. One day they did not take a sample in this time frame, so they collected the sample at 3 pm.
What went wrong?
Inconsistent! It could mess up their results!
Bonus: How might it alter their results?
300
The number of wildland fires are decreasing
300
A company has recycled 750,000 cotton t shirts in their new recycling program. Assuming a t-shirt has an average mass of 135 g, what method would you use to calculate the mass in kilograms that is recycled.
(750,000 t-shirts x 135 g)/1000g
300
If you get a question telling you to design an experiment, then this is the number of experimental groups the AP graders look for when reading your answers.
What is "2 or more"?
400
This was a popular pesticide for mosquitos which bioaccumulated in the tissues of top predators. Almost caused the demise of our national bird.
What is DDT?
400
Ms. Owens' biology class wanted to test the strength of Bess Beetles on various surfaces. They used carpet squares, wood, sandpaper, and whiteboard and measured the highest weight lifted using a pulley system.
What is the independent variable?
What is "the different types of surfaces?"
400
This type of graph would be most appropriate for visualizing how a increase in water temperature affects the number developing clams from fertilized eggs.
What is a bar graph?
400
A sanitary landfill has a leachate collection system installed below the surface to collect infiltrated rainwater. It is about 90% effective. If about 1440 m3 of rainwater infiltrates into the ground yearly, how much will the leachate collection system be able to treat? (In m3)
What is 1296 m3?
400
This is how ecological footprint is measured.
What is "global hectares?"
500
This disaster was technically not human-caused because it happened after an earthquake/tsunami, but it led to the meltdown of a nuclear reactor.
What is the Fukushima Nuclear Disaster?
500
What is wrong with this hypothesis?
"When the concentration of nanosilver particles in the water and the temperature of water are both increased, the population of zooplankton will decrease."
There are two independent variables!
500
These are the approximate sea height variations (mm) in 1995 and 2015.
What is 11 mm and 75 mm?
Bonus: What is the rate of change? (different from percent change)
500
A sanitary landfill with a surface area of 6000m2 receives a yearly rainfall of 300 mm. About 20% of that is runoff and does not infiltrate the ground. How much rain infiltrates the ground? (In m3)
What is 1440 m3?
500
This process occurs when an algae bloom (through many steps) results in lower dissolved oxygen levels in a body of water
What is Eutrophication?
