Identify the three states of matter.
The three states of matter are solid, liquid, and gas.

What tool can I use to measure the length of a book?
I can use a ruler, tape measure, or yard/meter stick.
100
Describe the shape and volume of a solid.
A solid has a definite volume and a definite shape.
100
What causes matter to change state?
The gain or loss of heat energy (thermal energy) causes matter to change state.

________ energy from the sun helps plants grow.
Light
200
Define matter.
Matter is anything that has mass and volume.
200
I want to measure the mass of a chair. Should I use grams or kilograms? Why?
I should use kilograms because a chair is a heavy object and kilograms are a larger unit than grams.
200
Describe the shape and volume of a gas.
A gas has no definite shape or volume.
200
What change of state occurs during melting? What causes this change?
Melting is the change of state from a solid to a liquid. It happens because a solid gains heat energy (thermal energy).
200
Adding __________ energy to a liquid causes it to change to a gas.
thermal
300
What is volume?
Volume is the amount of space an object takes up or how much a container can hold.
300
I want to measure the volume of a kitchen sink. Should I use liters or milliliters? Why?
I should use liters because they are larger than milliliters and a kitchen sink holds a large amount of water.
300
Describe the shape and volume of a liquid.
A liquid has a definite volume but no definite shape.
300
What change of state occurs during freezing? What causes this change?
Freezing is the change of state from a liquid to a solid. It happens because a liquid loses heat energy (thermal energy).

___________ energy from a drum can cause rice sitting on the drum to vibrate.
Sound

What is mass?
Mass is a measure of the amount of matter in an object.
400
If I want to measure the mass of a baseball what tool and units should I use?
I should use a balance scale to measure the mass and I should record the mass in grams.

Mary pours water, oil, and corn syrup into a graduated cylinder. What will she observe and why?
The liquids will form layers because they have different densities. The corn syrup has the greatest density and it will sink to the bottom. The water will sit in the middle. The oil, which is the least dense, will float on top.
400
What change of state occurs during condensation? What causes this change?
Condensation is the change of state from a gas to a liquid. It happens because a gas loses heat energy (thermal energy).

__________ energy can shock you if you drag your feet on the carpet and then touch a doorknob.
Electric (static electricity)
500
Which of the following is NOT matter: a lamp, a light bulb, a lamp shade, or the light produced by the lamp? Explain why you chose your answer.
The light produced by the lamp is not matter because it is energy. You cannot measure the mass and volume of light, so it is not matter.
500
If I want to measure the volume of a water bottle what tools and unit should I use?
I should use a graduated cylinder or measuring cup to measure the volume of the liquid and I should record the volume in milliliters.

Tim tapes a tissue into the bottom of a cup. He then turns the cup upside down and places it in a container full of water. Will the tissue get wet or will it stay dry? Why will this happen?
The tissue will stay dry inside the cup because air is inside the cup and this air stops the water from entering the cup. Even though we can’t see it we know a gas is there taking up space because it keeps the water out of the cup.
500
What change of state occurs during evaporation? What causes this change?
Evaporation is the change of state from a liquid to a gas. It happens because a liquid gains heat energy (thermal energy).
500
What is energy?
Energy is the ability to cause change.
