4. A comparison of the density of an object to the density of water (objects that sink have greater density than water; objects that float have less).
5. A force that pulls certain metals like iron toward a magnet.
6. Anything that has mass and takes up space.
7. The ability of a material to transfer heat or electricity.
9. A combination of two or more substances that can be separated physically.
12. A state of matter that has a definite volume but takes the shape of its container.

1. A material that easily transfers heat or electricity.
2. A characteristic of matter that can be observed or measured without changing the substance (e.g., color, texture, magnetism, conductivity, state of matter).
3. How much mass is in a given volume of an object; calculated by dividing mass by volume.
8. To mix evenly into another substance, forming a solution.
10. A material that does not easily transfer heat or electricity.
11. A state of matter without a definite shape or volume; it spreads to fill its container.
13. A state of matter with a definite shape and volume.
14. The amount of matter in an object; measured using a balance.
