What is the difference between mass and volume?

Mass is the amount of matter in a substance, and volume is the amount of space an object takes up. 

100

Would particles be moving faster in liquid water or ice?

In liquid water, as the particles of a liquid move faster and have weaker bonds holding them together.

Jupiter has the largest mass of all planets. Does this mean that Jupiter takes up more space than any other planet?

Not necessarily, as mass and volume are two different measurements. Volume is the amount of space something takes up. As it happens, Jupiter does have the largest mass AND volume but that is not always the case with other planets/solar systems.

Is grass a living thing? Explain your answer. 

Yes, because it meets all of the criteria (has cells, interacts with environment, reproduces, etc.)

100

Which tools do we use to measure the mass of a powder?


Scale, weighing tray.

200

Is color a characteristic property?

No, because a characteristic property can help you determine the identity of a substance. 

200

What is it called when a gas turns to a liquid?

Condensation

The temperature of Venus is 470 degrees Celsius. If travelling to the planet, what is one characteristic property that would be important to consider when choosing the material for your spaceship?

The melting point...Venus is very hot!

200

Does water have cells?

No, it is not an example of a living thing.

How do you check to see if a substance is an acid or a base, using pH paper?

1. Dip it into the substance. Take it out after several seconds. 

2. Wait a minute for the paper to turn color. 

3. Match the color to the pH chart.

Adam wants to fill up a glass with his favorite soda. Which property of matter will he need to consider to prevent his glass from overflowing?

Volume

Frost forming on the ground is an example of which change of state?

It is an example of deposition, because the gas directly becomes a solid.

Fill in the blanks....

A rover takes a soil sample from a planet in a distant solar system. The __________ of the soil is 3.5, indicating that the soil is an ______________.

pH, acid.

A robot interacts with its environment, moves, even can respond to stimuli. Why would we still not consider it a living thing?

It does not have cells, nor can it reproduce or make long term adaptations.

Write the correct procedure for testing electrical conductivity using an electrical conductivity kit. 

1. Attach one alligator clamp to the battery. 

2. Attach one of the electrodes to the alligator clamp from question #1.

3. Attach the other alligator clamp to the battery. 

4. Attach this alligator clamp to the light bulb. 

5. Attach your third alligator clamp to the other side of the light bulb. 

6. Attach this alligator clamp to the electrode. 

7. Touch the electrodes to make sure that the light bulb lights up. 

8. Place the electrodes, without touching, into/onto the substance that you are testing. Record if the lightbulb lights up.

What determines temperature?

-How quickly a substance can change between a solid and a liquid. 

-The movement and agitation of the particles of a substance. 

-The volume of a substance.

-The melting point of a substance

The movement and agitation of a substance.

Provide an example of condensation

Answers will vary, but must be a gas becoming a liquid.

Saturn has a volume that is 80% that of Jupiter, however it's mass is significantly less. What might be one explanation for why it's mass is less than Jupiter?

- It's surface has a very high pH.

-It's atmosphere is a mixture. 

-It is primarily made up of gases, which generally are lower in density (mass and volume relationship). 

-It's atmosphere is a poor conductor of electricity. 

It is primarily made up of gases, which generally are lower in density (mass and volume relationship) than liquids or solids. 

Keep in mind.....density is not part of the exam but you don't need to know about density to cancel out the other options!

A mouse from New Zealand and a mouse from Canada are both brought to a lab. How could a scientist determine if they are the same species?

-Observe their physical and behavioral characteristics. 

-See if they can reproduce, and if they can if their offspring are capable of reproducing.

What is the difference between observations and analysis on a lab report?

Observations are what is recorded (any numbers, changes, etc. that happen during the lab exercise) while analysis is explaining why the observations could have happened, using one's scientific knowledge.

How many milligrams are in a kilogram?

1,000,000

There are 1000 milligrams in a gram. 

There are 1000 grams in a kilogram. 

1,000 x 1,000 = 1,000,000

What is the difference between sublimation and deposition?

Sublimation is when a solid turns directly to a gas, and deposition is when a gas turns directly to a solid.

A scientist traveled to Mars for an oil expedition and found a mysterious solid frozen in a block of ice. They want to bring it back to their lab to determine if it is living or not. They want to make sure the ice stays frozen until they return. Assuming the ice is made up entirely of water, what temperature must they keep the block at for it to stay frozen. 

Below 0 degrees C

A hiker in the woods finds what they believe to be the carcass of a dead animal. They aren't sure however if what they found was ever living. What is one test they could do to determine whether or not it was once a living thing, assuming they have a science lab available to them?

They can look with a microscope to see if there are any dead cells on the carcass.

You are a scientist trying to determine if the pH of a lemon is an acid or a base. You are using pH paper to do your test. 

Write your Aim/Goal of your lab report and provide a hypothesis. 

Aim - To test the pH of a lemon. 


Hypothesis - I believe that the lemon will be an acid/base/neutral.
