Students gathered the following materials. What are the students trying to investigate?

• The students are trying to construct a circuit to investigate the conductivity of electricity.

• The students are investigating whether the materials dissolve in water.

• The students are investigating whether the objects will change states.

• The students are constructing a circuit to investigate the density of the materials.

The students are conducting an investigation. They have gathered the following materials and placed their observations below. Which physical property of matter are the students investigating?

• Density because only the iron nail is more dense than water

• Conductors of electricity because yarn, plastic straws, and copper wires do not allow electricity to flow.

• States of matter because all the materials are solid.

• Magnetism because copper wires, yarn, and plastic straws are not magnetic.

Students measured 100 ml of water and poured it inside a beaker. The teacher then asked the students to place 50 ml of water in the freezer and 50 ml of water in a hot plate for 20 minutes. What did the students most likely observe after 20 minutes?

• The water in the freezer became a solid while the water on the hotplate had evaporated.

• The water in the freezer stayed a liquid, while the water on the hotplate was boiling.

• The water in the freezer “disappeared: while the water in the hotplate stayed a liquid.

• Both the water in the freezer and the hotplate keep the same state of matter.

Water and sand are mixed together. Which of the following is true?

• Sand dissolves in water because it is soluble in water.

• Sand does not dissolve because it is soluble in water.

• Sand does not dissolve because it is not soluble in water.

• If you keep stirring, the sand will dissolve over time.
