Buoyancy
| Term | Definition |
|---|---|
| capacity | the amount of fluid an object can hold |
| graduated cylinder | a tool used to measure liquid in ml |
| milliliters | the measurement used to find capacity of boats |
| negative buoyancy | when the force of an object is greater then the buoyant force. It sinks. |
| positive buoyance | When the force of the object is less than the buoyant force. It floats. |
| buoyancy | the upward force that keeps things afloat |
| syringe | a tool to help collect fluids to measure capacity |
| neutral buoyancy | when the object and buoyant force are equal |
| Archimedes | a mathematician who help discover the idea of displacement and buoyant force |
| displacement | when water is moved out of the way by an object that is placed into the water |
| variable | the one thing you can change in an experiment that may or may not affect the outcome |
| controlled experiment | the first experiment you do where variables are controlled. All other experiments are compared to this experiment. |
| variables in the boat experiment | penny placement, wetness of pennies, sogginess of the boat, force used to put pennies in, waves in the water like bumping desk, |
