True or False
(Group 1)

What is the difference between a law and a theory?
Law = scientific observation that is definitely proven to be true
theory = scientific observation that is backed by evidence, but not definitely proven to be true
100
Which part of the core is solid: outer or inner? (group 4)
inner
100
At which plate boundary does a mid-ocean ridge occur: convergent, divergent, or transform?
divergent (group 3)
100
What is a system of interlocking and interdependent food chains?
a food web (group 6, part 2)
100
Consumers use Photosynthesis to make their food.
false
200
What is the difference between objective and subjective?
objective = stating what you see, without bias
subjective = your opinion of your observation
200
What are the characteristics of sedimentary, igneous, and metamorphic rocks? (group 3)
Sedimentary - Rough, its easy to break, pieces of sediment put together

Igneous- Air Bubbles or it's smooth

Metamorphic- Smooth, has crystals, has layers

200
What is the difference between convergent, divergent, and transform plate boundaries?
Divergent boundary is when two plates separate.
convergent boundary is when two plates come together
transform boundary is when two plates horizontally slide past one another. (group 4)
200
What is a decomposer?
is an organism who feeds off dead organisms. (group 6)
200
A mid-ocean ridge forms on a divergent plate boundary
true
300
What is the dependent variable?
The observed variable in an experiment that changes are determined by the presence or degree of one or more independent variables.

(from group 1)
300
What are the three types of rocks, and how do they form? (group 3)
Sedimentary Rocks, Metamorphic Rocks, Igneous Rocks

Sedimentary- Rocks that are formed when sediment is pressed together through compaction and cementation.

Metamorphic- Rocks that are formed By extreme heat and pressure underground.

Igneous- Rocks that are formed by the cooling and hardening of magma or molten lava.

300
What are the two types of tectonic plates on our Earth?
continental and oceanic
300
What is the difference between a food chain and a food web?
a food chain is one sequence and a food web is a group of food web (group 6, part 2)
300
The independent variable is the variable that the scientist controls.
True
400
Is something that is theoretical "possibly true" or "definitely true"?
"possibly true"
400
What is the continental drift theory? (group 8)
What is long ago all the continents were once all together its was a super continent called (Pangaea).time passed by and the continents were separated into large continents called Laurasia and god Gondwanaland and more time passed the continents separated more into the continents we have today.
400
Name the three arguments that support continental drift theory.
1. Continents fit together like a puzzle.
2. Fossils of the same species found on different continents.
3. Fossils of organisms found in places where they could not have possibly survived.
400
What is the definition of mutualism ?
a relationship between two organisms in which both benefit (group 6)
400
An animal or insect that eats plants is called a secondary consumer.
false- primary consumer
500
What is a limitation of using a scientific model?
Since it is not the same thing, you will not always get the same results as you would in real life.
500
Explain Carbon Dating.
The process by which scientists study the age of an organic substance by measuring the amount of Carbon-14 left with the amount of Carbon-12 in the material.
500
At which type of plate boundary can a subduction zone occur?
convergent (group 3)
500
Explain the process of photosynthesis using the following words: carbon dioxide, oxygen, glucose, sugar, energy, sun, and water.
In the process of Photosynthesis, plants absorb energy from the sun, water, and carbon dioxide. They create a sugar called glucose, and release oxygen as a byproduct.
500
The relationship between a flea and a dog is called predation.
false- parasitism (the dog does not typically die)
