What is the upward force that a fluid exerts on an object ?
100
Swim bladders in fish use this scientific property to survive.
What is buoyancy?
200
The amount of matter that makes up an object/substance.
What is mass
200
Is your mass different on the moon than it is on Earth? Explain
The amount of matter you take up does not change.
200
Explain how ice cubes float in a glass of water.
Ice cubes are less dense than water.
200
________________ buoyancy means an object/fluid sinks in another fluid
What is negative buoyancy?
200
Ballast tanks in submarines use this scientific property to submerge into water and resurface.
What is buoyancy?
300
The force of gravity acting on an object.
What is weight?
300
Is your weight different on the moon than it is on Earth? Explain.
The gravitational force is much less on the moon than on Earth. Therefore, your weight would be less on the moon.
300
Based on experiment in class, which fluid is the most dense: distilled water, salt water, vegetable oil or corn syrup?
What is corn syrup?
300
________________ buoyancy means an object/fluid remains suspended in another fluid.
What is neutral buoyancy?
300
How does a submarine submerge into water?
What is find their ballast tanks with water. This causes the submarine to be more buoyant than water.
400
The water that an object pushes out of the way.
What is displacement?
400
Using a ruler name one way you can find the volume of an object.
What is length x width x height?
400
Based on experiment in class, which fluid is the least dense than salt water: distilled water, vegetable oil or corn syrup?
What is distilled water or vegetable oil?
400
Name the object(s) from the Bill Nye episode, which has a neutral buoyancy?
What is a balloon tied to a rock?
400
How does a submarine resurface in the water?
What is fill their ballast tanks with air. This causes the submarine to be less buoyant than water (positive buoyancy).
500
__________ is the downward force acting on an object; ____________ is the upward force acting on an object.
What is gravity and buoyancy?
500
How would you find the volume of an irregular shape?
What is finding the amount of water it displaces?
500
What is the formula for calculating density?
What is mass divided by volume?
500
This type of animal is negatively buoyancy and spends substantial amount of time resting motionless on the seafloor because they sink if they are not swimming.
What is a nurse shark?
500
Explain how you are able to read a book while lying in the Dead Sea? Salt
The Dead Sea is 31% salt, causing it to extremely dense.
