The diagram shows the process of
melting
evaporating
freezing
condensing
What happens during EVAPORATION?
liquid becomes a solid
solid becomes a liquid
liquid becomes a gas
gas becomes a solid
Which object is a CONDUCTOR and will allow electric and thermal energy to flow and go through easily?
rubber
metals
fabric
glass
Which Item is under the wrong heading in the chart?
helium
water vapor
milk
ice cube
Which of the following items does not belong with the others because it is an INSULATOR?
A piece of paper
A metal paperclip
A tin can
An iron horseshoe
A student makes a model of the water cycle using a cup, water, and plastic wrap. After the student places the model near a sunny window, moisture forms on the inside of the plastic wrap. This model shows evidence of gas changing to liquid. Which process is this?
freezing
condensation
melting
evaporation
A teacher gives a student four clear sealed containers. Each container hold a different substance. The student records observations about the substance in each container. Based on the observations, which most likely holds gas?
container 1
container 2
container 3
container 4
A student classifies the objects shown based on their physical properties. Which property can NOT be used to classify these objects into more than one group?
magnetism
mass
electric conductivity
solubility in water
Students measure the mass of several substances and record results in the table shown. How many substances are solid?

All of them are solid
Objects that were accidentally dropped into a swimming pool need to be removed. These objects include foam cups, keys, and coins. Which of the following explains a useful method for removing the foam cups?
Foam cups are more dense than water and sink to the bottom. Someone will need to swim to the bottom to remove the foam.
Foam cups dissolve in water so the water will need to be boiled to evaporate the water.
Foam cups are less dense so they can be removed from the surface of the water by scooping out with a cleaning net.
Foam cups melt in water so there is nothing to remove.
A student mixes salt into a beaker of water. The salt can't be seen once it is mixed with water. This means that the salt -
dissolves in water.
melts in water.
condenses in water.
freezes in water.
Some people add sugar to their hot tea. Which property of the sugar remains the same when sugar is in the tea solution?
taste of the sugar
size of sugar crystals
color of the sugar
texture of the sugar
Salt and iron filings are the SAME SIZE. If they are mixed, how can the two substances be separated?
Use tweezer to remove each grain of sand.
Use a magnet to pull out the iron filings
Put the mixture in water.
Use a screen to separate by size.

Jan uses protective gloves to remove a hot pan from the oven. Why are the protective gloves necessary?
The gloves are conductors and allow energy to flow to her hands.
The gloves are insulators and stop heat energy from flowing to her hands.
The gloves are metal and will allow energy to flow to her hands.
The gloves will melt the pan.
Objects that were accidentally dropped into a swimming pool need to be removed. These objects include foam cups, keys, and coins. Which of the following explains a useful method for removing the keys and coins?
Keys and coins are less dense than water so a net can be used to scoop them out because they are floating.
Keys and coins dissolve in water. Evaporate the water and the items will be left in the pool.
Keys and coins melt in water. There is nothing to remove
The keys and coins are more dense than water. Someone will need to swim to the bottom of the pool and get them.
Some people add sugar to their hot tea. Which is a true statement about the sugar?
The sugar is denser than tea and sinks to the bottom.
The sugar dissolves in the tea to form a special mixture called a solution.
The sugar is less dense than tea and floats on top of the liquid tea.
The sugar dissolves which means it melted.
Which is a true statement about the density of the cork?
Cork has the least density and floats at the very top.
Water is less dense than oil and floats above oil.
The cork is less dense than water and floats above the water.
Oil is the most dense and sinks to the very bottom.
According to the chart, which statement is true about material #4?
The color is clear.
It has the most mass.
It is not soluble in water.
It is less dense than water.
Which object is a conductor?
Plastic spoon
Paper
Copper wire
Wood
Which object is an insulator?
Copper wire
Plastic
Aluminum foil

Trail mix
Salad
Gravel
evaporation
melt
freeze

None of these are true about oil.
Which is a true statement about dish soap?
Dish soap is the most dense and sinks to the very bottom.
Dish soap is least dense and floats at the very top.
Dish soap is more dense and sinks below water but more less dense and floats above syrup.
Dish soap is less dense and floats above water but more dense and sinks below syrup.
Which is a true statement about water?
Water is more dense and sinks below oil but less dense and floats above dish soap.
Water is the most dense and sinks to the very bottom.
Water is the least dense and floats to the very top.
