QSE1 Science Review

The table lists properties of four different objects. Which of the substances is sugar water and a paperclip?

• Samples 1 and 2
• Samples 3 and 4
• Samples 1 and 3
• Samples 2 and 3

A student classifies the objects shown based on their physical properties. Which objects can be classified as insulators?

• Cotton ball, plastic ruler, and a penny
• Metal paper clip, key, iron nail
• Rubber band, cotton ball, iron nail
• plastic ruler, rubber band, eraser

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 diagram below shows a mixture of salt and water. After the students mixed the salt, it dissolved in the water and created a new substance. How can the students separate this new substance?

• Use filter paper, the water will flow and the salt will stay on the filter paper.

• Use a hot plate, the water will boil and become water vapor while the salt stays behind on the beaker.

• Use a sieve, the sieve will hold the salt while the water flows to the beaker.

• Wait for the salt to separate from the water after 20 minutes because salt is less dense than water.
