5.  During this semester, we are going to learn about different types of forces.  Today we are going to learn about a force called buoyancy.  Buoyancy is the force that makes things float. Science Review Target: I can apply the Engineering Design Process to design an aluminum foil boat that will hold the most quarters.

6.  Buoyancy:  An upward force on an object immersed in a liquid equal in magnitude to the weight of the displaced liquid. Buoyancy Target: I can apply the Engineering Design Process to design an aluminum foil boat that will hold the most quarters.

7.  The buoyancy of an object is related to its density.  The density of an object is defined as, its mass divided by its volume. Density Target: I can apply the Engineering Design Process to design an aluminum foil boat that will hold the most quarters.

8.  Because of this, something that is small but heavy for its size (a coin for example) has a high density.  Something that is light for its size (a box full of Styrofoam peanuts, for example) has low density. Density Target: I can apply the Engineering Design Process to design an aluminum foil boat that will hold the most quarters.

9.  Things that have high density sink, while things with low density float.  Would the coin sink or float?  How about the box of Styrofoam ? Density Target: I can apply the Engineering Design Process to design an aluminum foil boat that will hold the most quarters.

10.  The buoyant force happens because water is pushed out of the way, or displaced.  The more water is displaced, the stronger the buoyant force.  Displace means to push a fluid out of the way and take its place. Displacement Target: I can apply the Engineering Design Process to design an aluminum foil boat that will hold the most quarters.

11.  Now think about a boat. If you put something heavy on it, does it rise or sink? Displacement Target: I can apply the Engineering Design Process to design an aluminum foil boat that will hold the most quarters.

12.  Now think about a boat. If you put something heavy on it, does it rise or sink?  Sink Displacement Target: I can apply the Engineering Design Process to design an aluminum foil boat that will hold the most quarters.

13.  Is more or less water displaced? Displacement Target: I can apply the Engineering Design Process to design an aluminum foil boat that will hold the most quarters.

14.  Is more or less water displaced?  more Displacement Target: I can apply the Engineering Design Process to design an aluminum foil boat that will hold the most quarters.

15. If a 2 pound block of wood displaces 3 pounds of water, will it float in water? Displacement Target: I can apply the Engineering Design Process to design an aluminum foil boat that will hold the most quarters.

16. If a 2 pound block of wood displaces 3 pounds of water, will it float in water? Yes, because the block of wood weighs less than the water it displaces. Displacement Target: I can apply the Engineering Design Process to design an aluminum foil boat that will hold the most quarters.

17. If a 5 pound block of metal displaces 1 pound of water, will it float in water? Displacement Target: I can apply the Engineering Design Process to design an aluminum foil boat that will hold the most quarters.

18. If a 5 pound block of metal displaces 1 pound of water, will it float in water? No, because the block of metal will weigh more than the water it displaces. Displacement Target: I can apply the Engineering Design Process to design an aluminum foil boat that will hold the most quarters.

19.  How does a boat stay afloat in the water?  Buoyancy - the ability of an object to float in water or air.  The buoyancy of an object is related to its density.  The buoyant force happens because water is pushed out of the way, or displaced. Science Review Target: I can apply the Engineering Design Process to design an aluminum foil boat that will hold the most quarters.

24. Aluminum Foil Boat Challenge Overview (Our Problem): You work for a large engineering corporation that designs boats. A large corporation is looking to hire your company to design a boat that can hold the most amount of merchandise. The rising costs of fuel is putting a damper on their profits so they want a boat that can hold more merchandise which means they can make less trips across the Pacific ocean to North America. You are in charge of the designing and testing of this project. You need to design a boat that can hold 20 quarters without sinking.
