Properties of Materials Quiz-Module 1

How can you test if a material is magnetic?

• Hold each material the same distance away from a lamp for the same amount of time.

• Hold each material close to a magnet. If it is attracted, or repelled by the magnet, then the material is magnetic.

• Attach each material to an electric circuit using a battery, light bulb, and wires.

How can you test if a material conducts electricity?

• Hold each material the same distance away from a lamp for the same amount of time.

• Hold each material close to a magnet. If it is attracted, or repelled by the magnet, then the material is magnetic.

• Attach each material to an electric circuit using a battery, light bulb, and wires

How can you test if a material has thermal conductivity?

• Hold each material the same distance away from a lamp for the same amount of time.

• Hold each material close to a magnet. If it is attracted, or repelled by the magnet, then the material is magnetic.

• Attach each material to an electric circuit using a battery, light bulb, and wires.

Materials have many different properties. For example, some bend easily, and some are magnetic. Maria is trying to find out about the properties of a balloon. She is doing an experiment using the equipment in the diagram. 

What question is Maria trying to answer with this experiment? 

• Is the balloon magnetic?

• Does the balloon conduct heat?

• Does the balloon conduct electricity?

• Can the balloon be stretched?

Look at the diagram below. Robin adds 20 drops of iodine solution into a beaker that already contains water and cornstarch. 

What will happen?

• There will be fizzing and bubbles of gas.

• The color of the water and cornstarch will change to dark blue.

• The color of the water and cornstarch will change to orange/brown.

• Nothing will happen.

This image shows an electronic scale. 

What is measured by the electronic scale?

• The length of a substance

• The weight of a substance

• The color of a substance

• The thickness of a substance

True or False: Matter disappears when you can no longer see it. (see hint below) 

(Hint- when dissolving salt in water, you can observe that the salt dissolves, but that the water is cloudy. Does that mean that the salt is not there anymore?)

• True

• False

How do you investigate the length of a material?

• Feel it carefully

• Smell it carefully

• Measure with a ruler

• Weigh with a scale
