| What is the metric unit for length in the metric system? | Meter |
| What is the equation for calculating area? | Length x width |
| What is the definition for matter? | Anything that has mass and takes up space |
| What is the definition for mass? | The amount of matter in an object |
| What is the definition for volume? | The amount of space an object occupies |
| What process allows you to find the volume of an irregular solid object? | Water Displacement Method |
| What piece of equipment measures mass? | Balance |
| What piece of lab equipment measures weight? | Spring scale |
| What piec of lab equipment is used to pulverize a vitamin? | Mortar and pestle |
| When a liquid is poured into a graduate, the liquid appears to be curved. What is the curve referred to as? | Meniscus |
