This causes the water levels (TIDES) at the beach to change during the day & night, 2 high tides, and 2 low tides
What is the gravity from the moon?
100
After something dies, the matter is consumed, broken down, and returned to the environment by these.
What are decomposers?
100
As the temperature of a substance increases, this happens to the molecules/atoms?
What is SPEED UP/MOVE MORE?
100
ALL waves transfer this ~ weather it's sound, ocean, earthquake, or light waves!!
What is ENERGY?
100
Our ideas about the atom have changed over time (atomic theory). Why?
What is New Evidence/New science?
200
This layer of EARTH has convection currents
What is the mantle?
(asthenosphere)

Plant cells are different from animal cells. The diagram below identifies four different structures in a plant cell.
Compared to the structures in an animal cell, which of the following structures is found ONLY in a plant cell?
BONUS ~ Name ALL 3 DIFFERENT parts of plant-animal cells?
What is a cell wall?
BONUS ~ chloroplasts & large vacuole?
200
This type of change in matter results in a new substance (ex- rusting)
What is a chemical change?
200
This results from an unbalanced force acting on an object
What is change in speed or direction?
200
The statement is an example of repetition?
A. Pour 50 mL of water down 4 inclined surfaces.
B. Roll a marble down the ramp from 10 cm, 20 cm, and 30 cm.
C. Take the mass of 5 rocks separately, then determine the average mass.
D. Conduct 4 trials of counting the bubbles produced by a water plant for 1 min each.
What is D? conduct MORE trials
300
This is the process of breaking down and movement of rock (2 words)
What is weathering & erosion?
300
This is evolution that occurs through beneficial traits being passed down to future generations. The traits that do not help organisms to survive are not passed down because those individuals die off before having the chance to reproduce (only the strong survive).
What is natural selection? survival of the fittest
300
This results when two or more elements combine chemically. Their properties change to form a new substance.
What is a compound?
300
These TWO factors influence gravity; Gravity is a force that pulls something else towards the center of it (sun pulling on planets).
What are MASS & DISTANCE?
300
Two rock samples have the same volume but different masses. They are placed in water. Sample A floats, but sample B sinks to the bottom.
Which sample has MORE MASS?
What is sample B?
D = M/V
400
The points labeled below represent the size of Earth, The Milky Way, The Moon, and the Sun. The approximate size of the solar system is labeled.
Which point would best represent the size of the Sun?
What is Y?
400
This is the percentage of homozygous dominant genes in this punnett square ~
What is 25% or 1/4?
HOMOzygous ~ SAME
HETEROzygous ~ DIFFERENT

Atoms are made of smaller molecules. Tell me what they are, where you find them in the atom, and their respective charges.
What are
protons ~ nucleus ~ positive
neutrons ~ nucleus ~ neutral
electrons ~ outside nucleus ~ negative
400
STATE the Law of Conservation of Energy
(it also applies to the Law of Conservation of Mass).
Energy is NOT created nor destroyed ~ it ONLY changes forms.
400
What is the atomic number of this element?
BONUS ~ how many protons are in the nucleus of this element?
BONUS BONUS ~ how many electrons are orbiting the nucleus?
What is 79?
79?

These phases of the moon (2) results in the largest tides
What is full/new moon?
500
In photosynthesis, chlorophyll in plants change carbon dioxide gas, sunlight, and water into what molecule? 
What is glucose/sugar?
500
Lithium, Sodium, and Potassium are all in the same column on the Periodic Table. This is the reason these elements in the same column/group on the periodic table
What is same number of outside/valence electrons?similar properties?
500
An airplane is trying to land (go down). Which of the following conditions would cause the model airplane to descend toward the ground?
A. The lift equals the drag
B. The lift is less than the weight
C. The thrust is equal to the weight.
D. The thrust is greater than the drag.
What is B ~ lift is less than the weight?
Unbalanced force downward
500
Solve this problem using the Law of Conservation of Mass:
Mass cannot be created nor destroyed
What is 30g?
