The INDEPENDENT VARIABLE is the variable that is ____MANIPULATED___ by a scientist.
To demonstrate the Law of Conservation of Energy a student riding a bicycle uses the brakes to slow and stop the bike. He concluded that friction caused the bicycle to stop. Which energy transfer best explains why the bicycle stopped?
Friction between the bicycle's brakes and the moving wheels caused mechanical energy to be transformed into thermal energy.

More fit and more likely to survive
More fit and less likely to survive
Less fit and more likely to survive
Less fit and less likely to survive
1. More fit and more likely to survive
Name the three types of rock?
IGNEOUS, METAMORPHIC and SEDIMENTARY
The DEPENDENT VARIABLE ________ as a result of the change made to the independent variable.
The DEPENDENT VARIABLE ___CHANGES_____ as a result of the change made to the independent variable.
What would be the types of energy from a GAS PUMP to the CAR

LAW or THEORY - This scientific term is for something that occurs the same way in nature EVERY TIME!
LAW
TRUE or FALSE - Fossils are found in metamorphic rocks.
FALSE
List the INDEPENDENT and DEPENDENT VARIABLES:
A study was done to find if different tires affect the braking distance of a car.
I.V.= Tires
D.V. = Braking distance
TRUE or FALSE - Energy can be created
FALSE

GAMMA RAYS have the most energy and highest frequency of the EM spectrum.
Which of the following best describes how the theory of evolution has changed over time ?
1- The theory of evolution describes a body of observations about the changes in organisms
2- Darwin's theory of evolution was modified to the current theory as new evidence was discovered
3- The idea of evolution did not develop until natural phenomena described what was happening
2- Darwin's theory of evolution was modified to the current theory as new evidence was discovered
How is a metamorphic rock formed?
A metamorphic rock is formed due to a lot of heat and pressure.
List the INDEPENDENT and DEPENDENT VARIABLES:
The amount of pollution produced by cars was measured for cars using gasoline containing different amounts of lead.
I.V.= amount of lead
D.V.= pollution.
What happens to a snow skier's potential energy while gliding down a ski slope?
Potential energy is transformed into an equal amount of kinetic energy as the skier moves down the slope.
Sound travels (faster or slower) ______ in solids than in gases.
Sound travels FASTER in solids than in gases.
Scientists have found 3 evidence that supports the theory of evolution.
Similarities in early development
Similarities in DNA
aaaaaand ?
Homologous structures
Explain weathering and erosion
Weathering breaks up the rocks and it gets ready for erosion. Erosion happens when rocks and sediments moved to another place by ice, water, wind or gravity.
Frank rolled a toy car down a ramp and timed how long it took for the car to reach the bottom of the ramp. After one trial, the student doubled the height of the ramp and added sandpaper to surface of the ramp. He conducted three more trials. After reviewing the data, the student concluded the height of the ramp had no effect on the speed that the car traveled. What is wrong about his conclusion?
Too many variables were changed during the investigation
