A table of different properties of four samples of matter is shown.

Which conclusion can be made about the samples based on the table?

• Sample 1 is made of plastic.

• Sample 2 is made of metal.

• Sample 3 is attracted to magnets.

• Sample 4 is less dense than water.

A cook uses the ingredients listed to prepare a meal. Which table correctly show the physical properties of these ingredients when placed in hot water? (5.5A)

A teacher gives a student four clear sealed containers. Each container holds a different substance. The student records some observations about the substance in each container. Based on these observations, which container most likely holds only gas? (5.5A)

• Container 1

• Container 2

• Container 3

• Container 4

A student was asked to compare the masses of four blocks that were all the same size but made of different materials. The student used a balance to compare the masses of two blocks at a time. The student repeated this process three more times with different pairs of blocks and recorded observations. Which list shows the blocks in order from least to greatest mass? (5.5A)

• Blocks N, M, L, P

• Blocks P, M, L, N

• Blocks N, L, M, P

• Blocks P, L, M, N

A student is asked to design a sleeve for a cup that will insulate thermal energy and not feel hot to the touch when the cup is filled with hot liquid. The student has four materials to choose from. Which of these materials is least useful as an insulator? (5.5A)

• Cardboard

• Aluminum

• Rubber

• Plastic

For an investigation a teacher dropped a bolt into a container of maple syrup and asked students to remove it without touching the syrup. The students first tried to use a strong magnet to remove the bolt, but it remained on the bottom of the container. They finally poured the syrup into another container to get the bolt out. Which of these best describes some of the bolt's physical properties? (5.5A)

• The bolt is magnetic and has the same density as the maple syrup.

• The bolt is nonmagnetic and more dense than the maple syrup.

• The bolt is nonmagnetic and less dense than the maple syrup.

• The bolt is magnetic and less dense than the maple syrup.

The table lists some physical properties of two objects. Based on their properties, which of the objects is most likely a metal? (5.5A)

• Object 1, because it is a solid that is less dense than water

• Object 2, because all metals float in water

• Object 2, because metals conduct thermal energy and electricity

• Object 1, because it can be used to provide insulation for thermal energy.

Students are investigating properties of objects. They observe four objects and record observations for each object in the table. Based on the students' observations, which of these tables properly identifies the objects? (5.5A)

A student measured out 10 mL of four clear liquids and added one drop of a different-colored dye to each liquid. One of the liquids was water. The student then carefully poured each liquid into a graduated cylinder and let the mixture settle for 30 minutes. The student observed that the liquids had separated into layers, as shown in the diagram. Which of these procedures would help the student identify the layer of water? (5.5A)

• Stir the liquids, let them settle, and then identify the bottom layer as water

• Drop a piece of ice into the graduated cylinder, let the ice settle, and then identify the layer just above the ice as water

• Add water to the graduated cylinder, let the mixture settle, and then identify the layer that increases in volume as water

• Carefully pour each layer into separate plastic containers, place the containers in a freezer, and then identify the liquid that takes the longest to freeze as water.
