Bill Nye- Buoyancy- Guided Viewing Worksheet
1. What does it mean to "displace" water? Explain.
Water displace is a technique used to measure the volume of an irregular shape object. Water displacement is where water gets pushed a side by another mass.
2. Explain why the clay ball sinks but the same size clay boat floats.
It pushes more fluid out of its way in relation to its weight. The amount of air inside of an object can also help it float. Boat can float because of the large amount of air inside the hull.
3. Thing displace as much water as they Weight
4. Who was Archimedes? What did he discover?
He was a Greek mathematician, physicist, engineer, inventor, astronomer. He is created with designing innovative machines, including siege engines and the crew pump that bears his name.
5. How do fish control their buoyancy? Explain.
Many bony fish possess a flexible gas bladder that can be filled with various gases. As the fish dives deeper, pressure increases, compressing the air, reducing volume, and there by effectively making the overall fish denser. The negative buoyancy now pushed the fish down, and it stars to sink. Such fish can add more gas into the gas bladder to increase its volume and return it overall to neutral buoyancy.
6. Define the following:
-Negatively buoyant: SINK - Positively buoyant: FLOAT - Neutrally Buoyant: in the MIDDLE
7. Explain how hot air balloons work.
The basic of how the balloon works is that warmer air rises in cooler air. This is because hot air is lighter than cod air a sit has less mass per unit of volume. Mass can be defined by the measure it how much matter something contains.
