Mass is how much 'stuff' is in an object, and we usually measure it in grams (g) or kilograms (kg). Volume is the amount of space that 'stuff' takes up, and we often measure it in milliliters (mL) or liters (L). Remember, even if two things look the same size, they can have different masses! And even if they have the same mass, they can take up different amounts of space!

| Term | Definition |
|---|---|
| 1. Mass | A. The amount of space an object occupies. |
| 2. Volume | B. A tool used to measure mass. |
| 3. Gram | C. The amount of matter in an object. |
