What is a biome?
A region that has similar climate, plants, and animals.

What is the atomic number?
This is the number of protons in an atom and identifies the element.

This origin-of-life theory states that life formed from non-living matter.
What is spontaneous generation?
200
This term describes how the atmosphere “behaves” over long periods of time, including averages of temperature, precipitation, and humidity.
What is climate?
300
What is an independent variable? Give an example within the context of an experiment.
A variable that is manipulated or changed before an experiment. For example, for a scientist who is testing the impact of caffeine on student test performance, caffeine would be the independent variable.

Define Ecology
The study of the relationship between living and non-living things

This image describes which characteristic in RAAGO.
Organization: Hierarchy of living things

What are isotopes? Give an example.
Atoms of the same element that have different numbers of neutrons, such as Carbon-12, Carbon-13, and Carbon-14.
300
In Redi’s experiment, this variable was changed to test whether life would form.
What was the lid (independent variable)?

What is weather?
Unlike climate, this term describes the atmospheric conditions over a short period of time, like temperature, humidity, and cloudiness.
400
What is a dependent variable? Give an example within the context of an experiment.
A variable that is measured at the end of an experiment. For example, for a scientist who is testing the impact of caffeine on student test performance, the student's test score would be the dependent variable.

What is the tundra?

A sport scientist investigates whether different types of shoes improve running speed. Define the independent variable, dependent variable, and controlled variables in this experiment.
Independent: Type of Shoes
Dependent: Running speed in seconds
Controlled: Age of students, nutrition, training, weather, and running distance length.

After Superstorm Sandy, there is significant research being done that observed how the storm impacted native populations of marine life along the shore area. Which E-word does this describe?
Ecology (the storm impacts marine life)

Using your knowledge of RAAGO, defend why a Liger is an exception to the rule of classifying living things.
A liger is a living organism but it cannot reproduce therefore it is an exception to RAAGO
** DAILY DOUBLE: NAME ANOTHER EXCEPTION TO THIS RULE

This dating method uses the law of superposition to determine whether rocks or fossils are older or younger than surrounding layers, but not their exact age in years.
What is relative dating?
500
What is Pasteur’s experiment? Why was it significant?
This experiment disproved spontaneous generation, led to the invention of pasteurization, and showed that heat prevents the formation of life from nonliving matter.

List all the aquatic biomes and provide an example of an environmental threat.
An aquatic biome is defined by the water it contains rather than land. Examples: Freshwater, marine, or estuary. It faces threats such as pollution and overfishing.
