What is independent variable?
What the experimenter changes in the experiment.
100
What is potential energy and what effects it?
Potential energy is stored energy based on height and mass.
100
Fill in the blank:
With unbalanced forces, objects will move in the direction of the _________________ force
Larger
100
Fill in the blank:
The lower into the ground the rock layer is, the _____________ is it.
Older
100
What is photosynthesis?
The process of plans making their own food.
200
What is the dependent variable?
What is effected by the independent variable, what is measured in the experiment.
200
What is kinetic energy?
Kinetic energy is energy of motion based on velocity and mass.
200
What is the law of conservation of matter?
Matter cannot be created or destroyed, only transferred.
200
What causes continents to move? (These also cause earthquakes and volcanos)
Tectonic plates
200
What is the formula for photosynthesis?
water + sunlight + carbon dioxide = glucose + oxygen
300
Sarah wants to measure if the amount of water given to the plant effects the height of the plant. What is the independent variable and what is the dependent variable?
Independent: amount of water
Dependent: Height of plant
300
Can energy be destroyed? If not, what can it be?
No, it can only be transformed
300
Does an object move with a balanced force or an unbalanced force?
Unbalanced
300
What is the phenomenon that occurs in the mantle and causes tectonic plates to move?
Convection currents
300
What is an adaptation and name the two types of adaptation.
Adaptations are structural or behavioral changes an organism does to survive. Behavioral and physical
400
What is the independent variable and dependent variable?
Independent: Type of game
Dependent: Amount of players
400
Which cart has the most potential and most kinetic energy?
Potential: 1
Kinetic: 3
400
Will the ball in the picture shown be kicked to the left or to the right? Why?
To the left because the player is kicking with more force to the left than the player to the right.
400
Name the 3 tectonic plate boundaries and describe each of them.
Convergent: When plates crash into each other
Divergent: When plates move away from each other
Transform: When plates slide past each other
400
A bear with thick fur and large claws eats a lot of fish before heading into hibernation to survive the winter. What is one physical and one behavioral adaptation the bear has?
Physical: fur and claws
Behavioral: hibernation
500
What is the independent and dependent variable?
Independent: Type of pet
Dependent: Number of students

500
Calculate the net force acting on the object and identify which direction it will move in.
5N to the right
500
Which plate boundary is occuring at location B? What is being formed at that boundary?
Divergent boundary. New crust/rocks/mountains/land is formed
500
What is biodiversity?
Variety of life on earth
