Which of these BEST describes the change in salt grains as they dissolve in water?
The grains change their chemicals until they become water.
The grains get higher in temperature until they melt into a liquid.
The grains get smaller in size until they can no longer be seen.
the grains are washed clean until they are perfectly clear.
Which statement about gases is NOT true?
Gas particles move freely.
Gases have definite shape.
Gases fill all available space in a container.
Water evaporates into gas.
Tina is standing beside a car with tinted windows. Which of the following shows that a tinted car window is reflecting light?
Tina can see through the windows.
Tina can see herself in the windows.
Tina can feel that the windows are solid.

What happens when a small amount of salt, seaweed, and sand mixes with water?
the salt clumps into larger pieces
the sand and seaweed mix with the salt, and you can still see all the solids
the sand breaks into pieces too small to be seen
the seaweed floats to the top
Circuit A is constructed using a 6-volt battery, copper wires, and a bell. Circuit B is constructed using a 9-volt battery, string, and a bell. Circuit A produced a sound, but Circuit B did not produce a sound. Which of the following most likely explains why circuit B did not produce a sound?
The electricity traveled in a complete path.
There was not a switch in the circuit.
The bell was designed to produce a small amount of sound energy.
the string is a poor conductor of electricity.
Some students were studying different types of mixtures. They stirred together one cup of oil and one cup of water in a large glass beaker. They observed that the water settled to the bottom and the oil floated to the top. Which of the following does this investigation demonstrate?
The oil completely dissolved in the water.
The oil maintained it physical properties.
The oil was more dense than the water.
The oil melted in the water.
Four small metal cylinders were filled with boiling water and placed into different containers. Which container was the best insulator?
Container 1
Container 2
Container 3
Container 4
The circuit has three lightbulbs and a bell. Which procedure will result in the green bulb operating, the bell producing a sound, and only one blue lightbulb operating?
Close Switch 1 and leave Switches 2 and 3 open
Close Switches 2 and 3, and leave Switch 1 open
Close Switches 1, 2, and 3
Leave Switches 1, 2, and 3 open
An old-fashioned metal toy is shown below. When the candle is lit, the carousel of horses begins to turn. Which of these is the source of energy that makes the carousel turn?
Thermal energy
Electrical energy
Mechanical energy
Sound energy
The picture below shows a spoon in a glass of water. Why does the spoon appear bent?
the light waves are refracted as they change speed when they pass from the water to the air
the light waves are reflected as they change speed when they pass from the water to the air
the light waves are absorbed when they pass from the water to the air
the light waves bounce off of the water
A student designed the circuit below. Which switches should the student close to produce ight energy only?
Switch 1 and Switch 3
Switch 1, Switch 2, and Switch 3
Switch 1 and Switch 4
Switch 2, Switch 3, and Switch 4
A student made a list of activities that involve energy. Which activities on the list are examples of the use of electrical energy?
Activities 1, 4, and 6
Activities 2, 5, and 6
Activities 2 and 3
Activities 3 and 5
The diagram represents four liquids that each has a different density. Which statement best describes the density of Layer C?
Layer C is more dense than Layer A and Less dense than Layer B.
Layer C is more dense than Layer B and less dense than Layer D.
Layer C is more dense than Layer B and less dense than Layer A.
Layer C is more dense than Layer D and less dense than Layer B.
The picture below shows the sun over the ocean. What does this picture demonstrate about the behavior of light?
the water reflected the light from the Sun
the water absorbed the light from the Sun
The water refracted the light from the Sun
light does not travel in straight lines
