True or False: A simple way to sort items into categories is by their size or color.
True. These are simple physical properties.
100
True or False: Most matter can change states easily throughout the day.
False. It takes extreme temperatures (hot or cold) to change the states of most matter.
100
True or False: A ripped book is a chemical change because a new, mini-book was formed.
False.
100
True or False: A physical change can be reversed.
True.

What order of the states of matter would an ice cube go through if left out in the hot sun?
It would start as a solid, then melt into a liquid, and then evaporate into a gas.
200
How are these items sorted? Set 1: Carbon Dioxide, Oxygen, Helium Set 2: Rug, Sand, a Shoe, and a Book
Set 1 is all gases and Set 2 is all solids.
200
Give an example of a solid, a liquid, and a gas.
Any acceptable answers. Solids may include, but are not limited to: items such as a sink, a pen, a TV, or a bowling ball. Liquids may include, but are not limited to: water, juice, milk, or pop. Gases may include, but are not limited to: oxygen, helium, carbon dioxide, carbon monoxide, nitrogen, and more.

How would you change melted, liquid plastic into a solid?
You can change it by letting it cool.
200
Give an example of a solution.
Possible answers: Kool-Aid, a milkshake, pop, etc.
200
Give two examples of mixtures.
Possible answers: A salad, Chex Mix, a toy bin full of various toys, a pencil pouch, etc.
300
In the Law of Conservation of Mass/Matter, matter cannot be _______________ or _________________.
In the Law of Conservation of Mass/Matter, matter cannot be created or destroyed.
300
Name two characteristics of liquid molecules.
Possible answers: The molecules are free-flowing; they take the shape of their container; and they in no particular pattern, but can move around easily.
300
Give two clues that a chemical change has taken place.
Clues include: a change of color, smell or texture; the material changes temperature without being heated or cooled; or bubbles begin to form on the material

Find the volume of a box with a length of 5 inches, a width of 4 inches, and a height of 10 inches.
5x4x10= 200 inches cubed.
300
What would you use to find the volume of an oddly shaped object?
A graduated cylinder.
400
Name two soluble and two non-soluble materials.
Soluble items can include: sugar, salt, food coloring, etc. Non-soluble items might include: sand or other solid items.
400
Which two states of matter assume the shape of their container?
A gas and a liquid assume the shape of their container. However, a gas does not have a measurable volume.
400
What can be done to a log to create a chemical change and what can be done to it to create a physical change?
For a chemical change, you can burn it. For a physical change you can saw it, chop it, cut it, etc.
400
Boxes A, B, and C all have the same dimensions. Box A weighs 35 lbs., Box B weighs 48 lbs., and Box C weighs 22 lbs. What can you conclude about these boxes?
You can conclude that Box B has the most mass and is more dense than Boxes A and C.
400
Why is water unique to the three states of matter?
It is unique to the three states of matter because it can easily move through all three of them by freezing into ice, melting back into water, or evaporating into a gas.
500
You are building a model airplane. The wings weigh 50 grams, the body weighs 300 grams, and the propeller weighs 25 grams. What can you conclude about the sum of the weight for the airplane once it's put together?
The weight of the airplane will be 375 grams. It will not gain or lose mass once it is put together.

Draw, label, and give a characteristic of a liquid molecule on the board.
Answer to be judged in person.
500
List the states of matters' molecule movement in order from the fastest to slowest moving.
Gas would be the fastest moving followed by liquid. Solid is the slowest moving since it mostly just vibrates.
500
Matter is anything that has ____________ and ____________.
Matter is anything that has mass and volume.

You are measuring the volume of an oddly shaped object in a graduated cylinder. The starting point of the water is 64 milliliters and it ends up at 100 milliliters once the object is placed in the water. Scientifically explain what has happened.
Possible answer: Since the object takes up space, it is displacing the water and causing it to rise. The object moves the water up 36 milliliters.
