100
Name the two types of lenses
What is concave and convex?
100
If I try to see if a chair sinks or float...what am I measuring?
What is density
100
True or false. You can reverse a chemical change.
What is false.
100
Name some parts of the geosphere.
mountains, rocks, magma, anything on the ground or associated with the EARTH part.
100
What is the difference between potential and kinetic energy.
Potential is stored energy and kinetic is moving energy.
200
What does a concave lens do? It bends light __________
What is bends light OUT
200
What is the formula for volume?
What is length x width x height
200
How do you tell if it is a physical change or chemical change?
Physical change just changes looks- it can be reversed. Chemical makes a new substance and cannot be reversed.
200
What is the hydrosphere?
All of Earth's water.
200
Give an example of potential and kinetic energy.
Potential would be stored at the top of a roller coaster, and kinetic would be the going down.
300
Convex bends light out. True or false?
What is false, it bends light IN!
300
If I have 2 graduated cylinders and I measure how much water is moved by my object, what am I measuring?
What is volume?
300
Give an example of a chemical change.
Burning anything digesting food rotting stuff rust
300
Name the water cycle in chronological order
What is evaporation, condensation, precipitation.
300
Moving parts is what type of energy?
Mechanical--- kinetic
400
Light travels in a straight line until it....
refracts, reflects ,or absorbs.
400
You cannot find density without ____? Then what do you do with them?
What is mass and volume. You divide mass by volume.
400
If I melt something, did I have a chemical change?
Nope, it was a physical change.
400
If I am studying the weather, which sphere am I looking at?
What is the atmosphere?
400
How is heat transferred? Explain conduction.
Conduction (touches), convection, and radiation
500
What will make light refract?
Lenses!
500
What is mass? How do you measure it?
Mass is how much matter is in something. We measure using a balance.
500
True or false, Eating a banana is a physical change.
False, it is chemical. You will never see that banana again!
500
Explain how the water cycle affects all three spheres.
It starts by evaporating from the hydroshere, then it condensates in the atmosphere, and precipitates to the geosphere, and runs back into the hydrosphere.
