Properties of Matter
Grade 5 - Science - Building Confidence
Observation: it leaves white dust when rubbed on dark paper. Which property is shown?
- electrical conductivity
- transparency
- powdery texture
- malleability
Which test would best check for water resistance?
- touch each sample with a magnet
- drop equal water amounts on each sample
- stretch each sample the same distance and release it
- place each material in a simple circuit gap
Which material best matches this evidence: it completes a circuit and lights the bulb?
- aluminum foil
- wax paper
- copper wire
- steel nail
The graph compares materials for water resistance. Which material rates highest?
- all are equal
- wax
- cloth
- paper
Why is elasticity useful for holding index cards together?
- the material's name is the only evidence needed
- matter has no measurable properties
- all materials share the same properties
- the property matches the job the material must do

- transparency
- magnetic attraction
- electrical conductivity
- water resistance
Which test would best check for elasticity?
- rub each sample once on black paper
- stretch each sample the same distance and release it
- press each sample around a cube
- touch each sample with a magnet
