1. Which statement best represents a gas? (SC.8.P.8.1.)
Particles move more slowly and are farther apart.
Particles move more slowly and are closer together.
Particles move more quickly and are farther apart.
Particles move more quickly and are closer together.
1. Which statement best identifies the movement of the particles in a liquid? (SC.8.P.8.1.)
The particles of a liquid move freely.
The particles of a liquid slide past each other.
The particles of a liquid vibrate and barely move.
The particles of a liquid do not move at all.
1. Which statement best identifies a solid? (SC.8.P.8.1.)
Particles barely move and are tightly packed.
Particles barely move and are farther apart.
Particles move more quickly and are farther apart.
Particles move more quickly and are tightly packed.
1. Which statement best identifies which of these models is a liquid? (SC.8.P.8.1)
Diagram A is a liquid, because its particles move the slowest and are tightly packed.
Diagram B is a liquid, because its particles move at a medium speed, and are sliding past each other.
C.
Diagram C is a liquid, because its particles move the fastest and bounce all over the place.
Diagram A and B are both liquids, because the particles are always touching.
How does the picture relate to the particles in a solid?
The cars are driving fast and switching lanes like the particles in a solid.
The cars are sliding past each other while driving the speed limit like the particles in a solid.
The cars are moving so fast you cannot even see them like the particles in a solid.
The cars are barely moving like the particles in a solid.
What happens when you add energy to a
liquid? (SC.8.P.11.1)
Freezing

1. What is true of all physical changes? (SC.8.P.11.1)
A new substance is formed.
A substance is altered in size, shape or form.
Something has to break.
Something has to be folded.
1. When the process of melting happens, what is happening with the molecules and the phase change? (SC.8.P.11.1)
The molecules are speeding up turning a solid into a liquid.
The molecules are slowing down turning a solid into a liquid
The molecules are speeding up turning a liquid into a solid.
The molecules are slowing down turning a liquid into a solid.
1. When the process of condensation happens, what is happening with the molecules and the phase change? (SC.8.P.11.1)
The molecules are speeding up turning a liquid into a gas.
The molecules are slowing down turning a liquid into a gas.
The molecules are speeding up turning a gas into a liquid.
The molecules are slowing down turning a gas into a liquid.
1. What happens when you add energy to a liquid? (SC.7.P.11.1)
Melting and it will turn into a
solid.
Freezing and it will turn into a
solid
Evaporation and it will turn into a
gas.
Condensation and it will turn into a
gas.
1. Marco accidentally broke a crayon while coloring. Which of the following best compares the broken crayon to the original crayon? (SC.8.P.9.1)
The density of the crayon has decreased since the crayon is smaller.
The crayon went through a chemical reaction since there are more pieces of the crayon.
The crayon went through a chemical change because the shape of the crayon changed.
The total mass of the broken crayon pieces are the same as the original crayon since matter was not lost.
1. What does the Law of Conservation of Mass state? (SC.8.P.9.1)
The amount of mass is changed in every experiment.
The amount of mass is increased in every experiment.
The amount of mass is decreased in every experiment.
The amount of mass stays the same in every experiment.
1. Brandon dissolved 10 grams of salt in 100 mL of water to form salt water. He then boiled the solution and the water boiled away. How much salt would be left in the beaker? (SC.8.P.9.1)
1 gram
10 grams
90 grams
110 grams
In fall, dead leaves fall off trees. Every day, animals eliminate waste. All animals eventually die. As a result, what happens to the mass of the Earth? (SC.8.P.9.1)
The mass of the Earth steadily decreases.
The mass of the Earth steadily increases.
The mass of the Earth stays about the same.
The Earth does not have a mass because it is too big.
What happens to the mass of a whole piece of paper when cut into pieces and placed in a pile? (SC.8.P.9.1)
The mass of the whole piece of paper will be less than the mass of the pile of paper.
The mass of the whole piece of paper and pile of paper will be the same.
The mass of the whole piece of paper will be more than the mass of the pile of paper.
The whole piece of paper doesn’t have a mass because it is too light.
