Density Scenarios Quiz Review

#1 Your family has decided to install a central heating system (like a natural gas furnace) in your new family room. Should the heating vents be installed near the floor or ceiling?

#2 After winning the lottery, your family decides to build a new indoor swimming pool. Your mom and dad insist on you wearing a life jacket at all times, but you say you can float in water, so why wear one? How might you prove this to your parents before the pool is built? (You must use math and use the words mass and volume.)

#3 On a very hot day, you enter the 7-eleven and walk on down the ice cream isle and notice the ice cream is kept in upright freezers. Man, is this ever lame! Why would a chest freezer be better?

#4 Diving and retrieving coins from the bottom of a pool is one of your favorite games. On a luxury liner (a huge ship) they have pools, but they use seawater. Your first trip to the pool on the ship is frustrating because you find that it is more difficult to get to the bottom of the pool (same depth as your home pool). Explain Why.

#5 On your cruise to the Bahamas you are offered to go fishing. Some of the best fishing is where a river meets the ocean and the type of fish you are fishing for lives in salt water. Would you put your fishing line in the deep or shallow water?

#6 You are playing outside with your Buzz Aldrin (or your Dracula doll) and you drop it accidentally into a long pipe full of water. You notice that it just barely sinks out of site and you can't get your arm into the pipe to find the toy. Knowing all about how to change the density of water from class, how do you retrieve the toy?
