How would you find the volume of an oddly shaped object?
Use a graduated cylinder with water in it. Place the item in the water and subtract the new water level from the original water level.
100
How would you be able to tell if a magnet has a strong magnetic field or a weak magnetic field?
You could tell if it's strong or weak by how much it can hold. If it's strong, it can hold more weight than if it's weak.

Where would you most likely find older fossils? Where would you most likely find younger fossils?
You'd most likely find older fossils in the bottom or deeper layers of earth. You'd most likely find younger fossils in the top or more shallow layers of earth.

An inference is an explanation based on your experiences, not by directly observing something. 

What inference could you make if your cat is constantly pawing at itself in the mirror?

Possible answers: It thinks there is another cat and is playing. -It is recognizing itself and is curious about its movements.

How are deltas and dunes alike?
They are both formed by sediment being eroded and deposited. 
200
What tools might you use in order to find the length of something?
A ruler, yard stick, meter stick, or a tape measure would be useful.

If you add red Kool-Aid mix to water, which of the following will likely happen?

a) the mass of the water will increase

b) the mass of the powder will increase 

c) the powder will dissolve and spread evenly throughout the water

d) the particles of powder will remain solid and float in the water

c) the powder will dissolve and spread evenly throughout the water

Where would you find an animal with big ears and a thin coat?
Likely in a desert region. The big ears allow them to hear predators and release heat. The thin coat has less insulation and keeps them cool.

There's a snow-covered mountain with a U-shaped valley. What was the main cause of this landform?

a) glacial ice  b) wind   c) running water   d) chemical weathering

a) glacial ice
300
Which is an example of deposition?

a) water and wind shape rock

b) a delta forms at the end of the river

c) ice breaks apart from a cliff

d) a river carries rocks and soil away from the river bank

b) a delta forms at the end of the river

When you write a paragraph after a scientific method experiment in order to share your findings with classmates, you are....

a) stating an opinion

b) collecting evidence

c) communicating your results

d) forming a hypothesis

c) communicating your results

Which of the following would be best to make a switch on a circuit so it will conduct electricity?

a) cotton     b) plastic   c) wood   d) metal

d) metal. Metals are good conductors of electricity.

After wiping down the table with a wet cloth, it stays wet for a little while. Which word would explain why the water will disappear?

a) melting    b) condensation c) evaporation   

d) absorbing 

c) evaporation

What do the numbers on a thermometer mean?
They are the degrees of temperature in either Celsius or Fahrenheit. 
400
When we freeze water, it expands (more volume), but does that mean it has more mass (amount of water)?
No. The amount of water will stay the same whether it is frozen and melted over and over again. Its mass will stay the same, but it's volume may increase. 
400
What is something that helps a tortoise survive?
It's hard, outer shell protects it.

Which explains how the increased slope of a landform affects running water weathering and erosion?

a) The slope of a landform causes running water to drop sediments faster. 

b) The slope of a landform increases weathering, but not erosion. 

c) The slope of a landform increases the rate of weathering and erosion. 

d) The slope of a landform causes particles in rock to press together. 

c) The slope of a landform increases the rate of weathering and erosion.

Weathering is when rock is ____________.

Erosion is when _________________.

Deposition is when ___________.

Weathering is when rock is broken down into smaller pieces (sediment).

Erosion is when the sediment is picked up and moved by wind, moving water, gravity, or glaciers.

Deposition is when the sediment or rock is dropped off or deposited in a new spot.
