100
An object will float when the density of the object is less dense than water.
What is true?
100
This is what happens to the mass of an object, when you change the shape of the object.
What is nothing?
200
The unit of measure for mass.
What is grams?
200
To move or push aside.
What is displace?
200
The occupation or profession of Archimedes.
What is a mathematician?

A ship will float lower in salt water because it is more dense.
What is false? Salt water is more dense that fresh water.
200
These are two ways to make an object that previously sank, now float.
What is change the shape of the object, to high walls, and a flat bottom?
300
What all objects are made up of.
What is matter?

Ships sailing in the North Atlantic water will float higher then when they sail in a tropical ocean.
What is true? Cold water is denser that warm water.
300
These two forces are working opposite each other when an object is in water.
What are gravity and buoyancy?
400
The measure of the force of gravity on all objects.
What is weight?
400
An object that neither sinks nor floats.
What is neutral buoyancy?
400
Eureka!, means this.
What is "I have found it!"?
400
Ships captains' need to know the buoyancy levels of different waters so they can know how fast they can sail.
What is false? They need to know how much cargo they can safely load onto their ships.
400
This is why a larger ship can hold more cargo than a smaller ship.
What is increased buoyancy?
500
He developed the law of attraction.

People can float very high when floating in the Dead Sea in Israel.
What is true? The Dead sea contains salt water and salt water is more dense.
500
