States of Matter
This state of matter has a definite shape and volume.
What is a solid?
A material that allows electricity to flow through.
What is a conductor?
True or False: All metals are magnetic.
What is False
The amount of matter in an object is called ____.
Mass
Grouping objects by shared properties is called ____.
Classifying
This state takes the shape of its container but has a definite volume.
What is a liquid?
A material that does not allow electricity to pass.
What is an insulator?
Name a magnetic material.
Iron (steel, nickel, cobalt, gold, silver)
We measure mass using this tool.
Balance scale.
Classify a wooden block: state, conductor/insulator, magnetic?
Solid, insulator, non-magnetic.
This state has no definite shape or volume.
What is a gas?
Is aluminum foil a conductor or an insulator?
What is a Conductor
Why isn’t a penny magnetic?
It is not made of a magnetic metal.
Which has more mass: a marble or a crayon?
Marble (if heavier in lab setup).
Why do scientists classify objects?
To organize information and compare materials.
The particles in this state are spread out and move freely.
What is gas?
Name one conductor and one insulator from our lab.
Conductor = penny/paper clip; Insulator = rubber band/straw.
In our lab, name one object that was magnetic.
Paper clip, nail, etc.
Mass is different from weight because…
Mass doesn’t change with location, weight depends on gravity.
Which property would you use to tell apart a coin and a sponge?
Mass or density.
Draw the particle arrangement for solid, liquid, and gas.
Solid = close-packed, Liquid = medium-spaced, Gas = spread out.
Why do we use rubber around wires in houses?
Rubber is an insulator that keeps us safe.
Explain how magnetism is a physical property.
It can be observed/tested without changing the substance.
Why do scientists compare objects’ masses?
To classify and describe matter.
Pick an object in the classroom and describe it with at least 3 properties.
Example: Scissors = solid, conductor, magnetic, heavy.
