Science Review

If two objects are made of the same type of wood, the larger one will have —

• A higher temperature

• less mass

• more mass

• less eight

Which state of matter has a definite shape?

• Solid

• Liquid

• Gas

• water

If sand and pebbles were mixed in a cup, how could you separate them?

• Heating them and collecting what is left

• Soaking them in water until the sand disappears

• Touching them with a magnet and keeping only the part that sticks

• Pouring them into a strainer and catching what falls through

Which picture that shows mechanical energy.

• Person sitting in a chair

• Phone

• Bike leaning on a pole

• A bowling ball hitting pins and making them fall

A physical property of matter that can be measured with a balance is –

• Length

• Color

• Mass

• Temperature

When the state of matter is a gas it —

• has a definite shape.

• has no mass.

• can be seen easily.

• expands to fill its container.

The balance allows us to compare what property of the two blocks?

• Ability to sink or float

• Magnetism

• Mass

• Temperature

A mixture is made with rocks and marshmallows that are about the same size. What would be the best way to separate this mixture?

• by using a magnet to pull the rocks out of the mixture

• by using a strainer to separate the rocks

• by using water to cause the marshmallows to float

• by putting the mixture in the Sun to melt the marshmallows

Pulling on a wagon will most likely change all of the following EXCEPT it’s-

• Motion

• Position

• Diection

• Mass

If this magnet pushes the object away, the object must -

• Be made of rubber

• Be a liquid

• Be made of plastic

• Be a magnet
