What is anything that has mass and takes up space?
What tool is used to test whether an object is magnetic?
What is a magnet?

What is mass?
Mass is the measure of how much matter is in an object.
Define conductor.

Define relative density.
What is whether an object sinks or floats in water?
What tool is used to measure the mass of an object?
What is a triple beam balance?

What tool would you use to measure the relative density of an object?
What is a bucket of water?
Name 4 objects or materials that are LESS dense than water.
Answer may include: Oil, rubbing alcohol, styrofoam, cork, wood (i.e. toothpick), Ping pong ball
What physical property could you use to place these items in the SAME group? styrofoam cup, ping pong ball, wood
density
Define insoluble.
What is something that does not dissolve in a liquid (usually water)?
What tool would you use to determine whether an object is an electrical conductor?
What is a simple circuit?
Explain changes in physical state using water as an example.
Water is a liquid. When you add heat, it evaporates and becomes a gas. When you take heat away from water vapor, it condensates and becomes a liquid again. When you take heat away from water, it freezes into solid ice. When you add heat to ice, it melts to become a liquid.
Desribe the physical characteristics of a gas using as many physical properties as possible.
No definite volume, no definite shape, not an insulator, not magnetic, less dense than water, insoluble
