Can the mass of an object change?
Which of the following objects would be malleable?
Density is how much matter (mass) is packed into a certain space (volume). Density tells us if something will float or sink in a liquid. The more matter that is tightly packed in a given volume, the denser the object is.
Examples of density:
Oil and Water: Oil is less dense than water, so it floats on top.
A rock: A rock is denser than water, so it sinks.
A balloon filled with air: The balloon is less dense than the same amount of air outside the balloon, so it floats.
A piece of wood: Some wood is less dense than water, so it floats, while other wood is denser and sinks.
Which of the following items are denser than water?

Electrical Conductor | arrow_right_alt | A material that does not let electricity flow through it. It's like a barrier that keeps electricity from passing through. Examples include rubber, plastic, and wood. |
Electrical Insulator | arrow_right_alt | A material that allows electricity to flow through it easily. Metals like copper and aluminum are good conductors, which is why they're used in wires. |
