Purpose
This interactive allows you to explore the concepts of buoyancy or flotation.

Using the interactive

• Configure the interactive using the INITIAL SETTINGS template on the upper right-hand side.
• Control the running interactive using the CARGO template on the lower right-hand side.
• The lower left shows a table of the numerical data which changes as cargo is added.

• Volume: Determines the total volume of the ship. The mass of the ship is always 5 grams.
• Medium: Select which fluid medium into which the ship will be placed.
• Start: This button places the ship into the medium.
• Next Mass: This slider controls the mass of the next piece of cargo placed in the ship.
• Add Cargo: This button places another cargo item into the ship.

1			You may want to use a calculator during this demonstration. Examine the data in the table on the lower left corner of the interactive. When placed into the water, will the ship sink or float?
			A)	It will sink.
			B)	It will float.
			C)	The answer cannot be determined from the given information.
2			Note that the graduated cylinder reads 5 cubic centimeters. Observe and note that this is the amount of water that would be displaced by a 5 gram of greater volume. If 5 grams are placed into the ship, will the ship sink or float?
			A)	It will sink.
			B)	It will float.
			C)	The answer cannot be determined from the given information.
3			With an additional 5 grams in the ship, how much water will be in the graduated cylinder?
			A)	5 cc
			B)	10 cc
			C)	15 cc
			D)	20 cc
4			How much more mass can be added to the ship before it will sink?
			A)	1 gram
			B)	5 grams
			C)	10 grams
			D)	15 grams
			E)	20 grams
