Bill Nye: Buoyancy Notes
Hello, world! How you doing? Today we watched a video of Bill Nye. I remember when I watched him in class. He was so funny. Anyways, he was talking about buoyancy and we took notes on the video. Now I will put these notes on my website for all of you to see. Enjoy! Oh, I almost forgot. Peace!
1. What does it mean to "displace" water? Explain.
> When the water is pushed out of the way due to an outside force or object.
2. Explain why the clay ball sinks, but the same clay boat floats.
> The shape of it made a difference, in other words, surface area.
3. Things displace as much water as they what.
> Weigh
4. Who was Archimedes? What did he discover?
> Archimedes was a Greek guy 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, in other words, neutral.
7. Explain how hot air balloons work.
> If you displace hot air, you'll go up and float.
> When the water is pushed out of the way due to an outside force or object.

Wow, finally at the end of the notes. Well, now that I am done with the notes, I'm going to go now. Thank you so much for always reading my articles and I hope to see you reading them even more. I'll see you soon. Peace!
