BUOYANCY LAB
1. What does it mean to "displace" water? Explain.
> When gets "pushed" out
2. Explain why the clay ball sinks, but the same clay boat floats.
> It depends on the shape of the object. If an object is shaped like a ball it sinks
3. Things displace as much water as they what.
> Weigh
4. Who was Archimedes? What did he discover?
> Archimedes was a Greek "scientist" who discovered that you can figure out how much volume of an object there is if he knew how much water it displaced.
5. How do fish control their buoyancy? Explain.
> Fish have swim bladders. The fish bladder lets them regulate the air inside them to keep them buoyant.
6. Define the following words:
*Negatively Buoyant:
> The object will sink.
*Positively Buoyant:
> The object will float.
*Neutrally Buoyant:
> The object will stay in between, neutral
7. Explain how hot air balloons work.
> If you displace hot air, you'll go up and float.
> When gets "pushed" out
