Three forms of energy being used when the projector is turned on.
What are thermal energy, electrical energy, and light energy. (sound if the speakers are turned on)?
100
A rock made from molten lava that has cooled off.
What is igneous rock?
100
A change in characteristics over time.
What is evolution?

Katie developed an experiment for the following question: How does the type of soil effect the growth of the plant? Name the dependent variable.
What is the growth of the plant?

The reason why many people in Florida choose to buy white cars instead of black.
What is black absorbs more solar energy from the sun, making the car hotter. White reflect UV rays, thus absorbing less energy than black cars. They car stays cooler.
200
As the wavelength increases, the frequency ___________.
What is decreases?
200
Tectonic plates make up this layer of the Earth.
What is the lithosphere?
200
The ability of a species to survive and reproduce.
What is natural selection (or survival of the fittest)?
200
Formula for solving density.
What is M/V ?
200
When water turns to ice, energy ________.
What is decreases? The particles that contain the water have less energy.
300
The reason you can see a rainbow when white light passes through a prism.
What is white light bends, or REFRACTS, and white light separates into all colors of the rainbow?

Give three forms of evidence that prove Alfred Wegener's theory of continental drift.
What is similar fossils found in South America and Africa? What is the ancient glacier evidence? What is the continents fit together like puzzle pieces? What is similar rock formations found in different continents?

This process of cell division forms body cells and creates identical clones of the parent.
What is mitosis?
300
Standard unit used to measure distance by scientist.
What is meter?
300
The movement or transportation of sediments.
What is erosion?

When you touch the metal on the side of your desk, describe how thermal energy moves. It is an example of this type of heat transfer.
What is heat moves from your hand to the metal until they are the same temperature? It is an example of conduction because it involves direct contact.
400
Two types of boundaries that form volcanoes.
What are divergent and convergent subduction zones?
400
The reason heterotrophs are different from autotrophs.
What is autotrophs can produce their own food, while consumers do not have chloroplasts, so they cannot make their own food?

Jessica investigates how temperature effects the rate at which a chemical reaction takes place. She performs 3 trials to ensure reliability of the experiment. Her classmate, Mark also conducts the same exact experiment, also performing 3 trials. How is there repetition in this experiment? How is there replication?
Repetition is the numerous trials. Replication is Mark also performing the same experiment to ensure reliability.
400
Give two types of plate boundaries that form earthquakes.
What are transform and convergent subduction zones?
500
Explain how the food chain demonstrates the law conservation of energy.
What is energy is not destroyed or created along the food chain. Instead it is used up and turned into new forms of energy (such as heat), and it transferred from one consumer to the next. The energy decreases as it passes through the food web.
500
Name the 2 ways that we can find the ages of rocks.
What is relative dating (using the law of superposition) and absolute (or radiometric) dating?
500
A short big toe is a dominant trait in humans, T, while a long big toe is the recessive trait, t. What percentage of offspring will have a long big toe if the parents genotypes are Tt and tt?
What is 50%?

Describe two of the three ways scientists measure volume.
What is a graduated cylinder for liquids? For regular shapes, l x w x h ? For irregular shapes, water displacement?

Mussels grow on the roots of red mangrove trees in the Florida Everglades ecosystem. This benefits the mussels because if gives the mussels protection from predators. The mussels do not help or harm the red mangroves. Name the type of symbiosis.
What is commensalism?
