Changes in an organism over time that help that organism to survive in a particular ecosystem.
What are adaptations?

By creating a closed circuit, an object that needs electricity to operate will work. An example of this would be light in a room. When the light is working, it creates a closed circuit. If the circuit is open, the light in the room will do this.
What is turn off?
100
Anything that has mass and takes up space.
What is matter?

A man is bowling at his neighborhood bowling alley. The bowling alley has lanes in which bowlers roll the bowling balls down a long, narrow, wooden path trying to knock down ten large, white pins at the end. This is a reason why they might the put wax on the wooden lanes. A. The wax reduces friction and makes it easier for the ball to roll. B. The was makes the lanes shiny. C. The was makes the lanes bumpy and harder to aim at the pins. D. The was makes the ball roll slower because it increases friction on the ball.
What is A. the wax reduces friction and makes it easier for the ball to roll?

This is the movement of Earth materials by forces such as wind, moving water, ice forming, and gravity.
What is erosion?
200
This is one way that humans positively and negatively affect ecosystems. (one way for each)
Positive: What is by recycling? What it by establishing rain gardens? What is by planting native species to prevent flooding and erosion? Others... Negative: What is by not littering? What is by not recycling? What is by overusing fertilizers? Others...

Energy can be ___________ from one form to another.
What is transferred?
200
These are the three physical states that substances can exist in.
What are solid, liquid, and gas?
200
A push or pull.
What is a force?
200
A. Oxygen B. Natural gas C. Soil D. Plants Of these examples, this is a non-renewable resource.
What is B. Natural gas?
300
These make their own food using energy from the sun.
What are producers?
300
This is a part of a circuit that allows you to easily open and close the circuit.
What is a switch?
300
This is a measure of how strongly an object is pulled down toward the ground by gravity.
What is weight?
300
A stopping force that is produced when objects are in contact with each other. It acts against motion and may be reduced by using lubricants such as oil or water.
What is friction?
300
The following human activities is one that might harm the carbon dioxide - oxygen cycle. A. People are excercising more. B. Farmers planting more trees. C. People planting trees when they cut trees down for lumber, or wood. D. People cutting down the rainforests around the world.
What is D. People cutting down the rainforests around the world?

Every trait that an offspring inherits is determined by the genes of its parents. Genes contain DNA. Genes are on chromosomes. All of the following are traits that may be inherited from the parent EXCEPT this. A. eye color B. height C. skin color D. hairstyle
What is D. hairstyle?

A radio is an example of this kind of energy transfer.
What is electric to sound?
400
The total amount of matter __________ when it undergoes a physical change such as when an object is broken into tiny pieces, when a solid is dissolved in a liquid, or when matter changes state.
What is is conserved (stays the same)?
400
These cause a change in the motion of objects.
What are unbalanced forces?
400
This causes day and night on Earth.
What is the rotation or spin of the Earth.
500
These eat producers and/or other animals.
What are consumers?
500
This kind of circuit allows more than one path for the electricity to flow.
What is a parallel circuit?
500
Ice melting is an example of this kind of change.
What is a physical change?
500
If an object is at rest or in motion, it wants to stay at rest or in motion because of this force.
What is inertia?
500
This is the breaking down of rock into pebbles and sand caused by physical processes such as heating, cooling, and pressure, and chemical processes such as acid rain.
What is weathering?
