Students wanted to see if the distance a marble rolled down a ramp changed the force it had. They allowed a marble to roll down the ramp from different starting points and strike a second marble. To determine if the force of the rolling marble changed, what should the students measure?
The mass of Marble #2 before and after being struck by Marble #1.
The distance Marble #2 moves after being struck by Marble #1.
The time it takes Marble #2 to move after being struck by Marble #1.
The direction Marble #2 moves after being struck by Marble #1.

Based on the observations shown here, which surface had the greatest amount of friction?
Surface A
Surface B
Surface C
SurfaceD

The diagram below shows a mixture of salt and water. After the students mixed the salt, it dissolved in the water and created a new substance. How can the students separate this new substance?
Use filter paper, the water will flow and the salt will stay on the filter paper.
Use a hot plate, the water will boil and become water vapor while the salt stays behind on the beaker.
Use a sieve, the sieve will hold the salt while the water flows to the beaker.
Wait for the salt to separate from the water after 20 minutes because salt is less dense than water.
The table lists the ingredients of five different mixtures. In which mixtures do all the ingredients maintain their physical state?
Mixtures 3 and 4 only
Mixtures 1, 3, and 4
Mixtures 1, 2, and 5
Mixtures 2 and 5 only
A student made a mixture using equal amounts of salt and pepper. The salt grains were the same size as the pepper grains. What should the student do to most easily separate the pepper from the salt?
Use a pair of tweezers to remove each grain of pepper
Run a small magnet through the mixture to attract the pepper
Put the mixture of water and filter the pepper out of the water
Use a strainer with a fine wire screen to remove the pepper
Which change occurs when lemon juice is mixed with water?
The mass of the lemon juice decreases.
The water becomes a solid
The lemon juice dissolves and spreads out evenly in the water
The volume of the water decreases
A solution is made when one substance _________ in another.
settles at the bottom
moves
dissolves
is suspended
