Density
Buoyancy
Science in Our World
100
The amount of space an object/substance takes up.
What is volume?
100
Define volume.
What is the amount of space an object takes up?
100
What two properties is density dependent on?
What is mass and volume?
100
Define buoyancy.
What is the upward force that a fluid exerts on an object ?
100
This flammable gas (less dense than air) was used in the airship the Hindenburg.
What is hydrogen?
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 if you go here.
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: alchohol, salt water or tap water?
What is salt water?
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, this altered the density of the raisins. Be specific
What is carbon dioxide in soda water?
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
The formula for calculating density.
What is mass divided by volume?
500
This part of bony fish help to alter buoyancy.
What is a swim bladder?
500
Explain how you are able to read a book while lying in the Dead Sea?
The Dead Sea is 31% salt, causing it to extremely dense.
