A student wants to classify four different objects based on physical properties. The student uses the questions shown in the table to test ech object. Which statement correctly identifies two of the materials based on the classification of properties in the table? (TEKS 5.5A 2019-Q30)

• Material 1 is a rubber ball.

  Material 2 is a piece of cardboard.

• Material 2 is an aluminum washer.

  Material 3 is a copper wire.

• Material 3 is a piece of cardboard. Material 4 is an aluminum washer.

• Material 1 is a copper wire. Material 4 is a rubber bll.

The table list some physical properties of two objects. Based on their properties, which of the objects is most likely a metal? (TEKS 5.5A 2018-Q5)

• 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 the 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? (TEKS 5.5A 2018-Q16)

A student measured 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 show in the diagram. Which of these procedures would help the student identify the layer of water? (TEKS 5.5A 2018-Q29)

• 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 increased 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.

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 n 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? (TEKS 5.5A 2017-Q30)

• 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 that the maple syrup.

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

Two wires carrying electricity can create a spark if they come to o close together. This spark can start a fire. Wires carrying electricity are usually covered with plastic to keep the from starting a fire. Why does the plastic keep the electricity from starting a fire? (TEKS 5.5A 2016 Q1)

• Plastic is a good insulator.

• Plastic can melt when heated.

• Plastic is softer than wire.

• Plastic conducts electricity.

A student puts four objects in a bucket filled with water. The objects are listed in the image. Which two objects are most likely less dense that the water? (TEKS 5.5A 2016 Q18)

• Wood block and metal paper clip

• Plastic ball and glass marble

• metal paper clip and glass marble

• Wood block and plastic ball
