A teacher mixes a white powder into a beaker of water. The powder cannot be seen in the water. The teacher then heats the mixture until the water evaporates and the powder can be seen again. Which property of the powder is the teacher demonstrating? (5.5A)

• Solubility

• Relative density

• Conductivity

• Mass

A teacher sets up an experiment using five jars. The teacher keeps one jar unwrapped, and the other four jars are wrapped with equal thicknesses of four different materials. Which property of the materials wrapping the jars are the students most likely investigating? (5.5A)

• State of matter

• Thermal energy insulation

• Thermal energy production

• Ability to conduct electricity

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

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.

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.

A student adds 10 grams of four different powdered solids into four different beakers. The student then adds 100 mL of water to each beaker, stirs the mixtures, and allows them to sit for half an hour before recording observations. Which question is the student most likely trying to answer with this investigation?

• At what water temperature do the substances dissolve?

• How much water is needed to cause a substance to change state?

• What causes a substance to sink when put in water?

• Which substances dissolve in water?

A mixture of beads was placed in a container, as shown below. The beads are of various sizes, and each one is made of plastic, glass, or steel.

The mixture would be easy to separate because all the beads —

• A are less dense than water

• are solids

• have the same mass

• are attracted to a magnet

• F

• G

• H

• J

• A

• B

• C

• D
