Which of the following titles would most accurately complete the missing information in the concept map above?

• Volume of air
• Components of air
• Atmospheric pressure
• Rocket-fuel ingredients

When the glass reaches the bottom of the tank, the sugar cube will most likely

• stay dry, because the air in the glass will expand.
• stay dry, because the air in the glass will take up space.
• get wet, because the water will exert less pressure than the air.
• get wet, because the water will exert more pressure than the air.

The studets in 6W designed paper airplanes and conducted a test to see which paper airplane would travel the farthest distance. Each student also attempted to describe Bernoulli's Principle. Which student correctly described Bernoulli's Principle?

• Nico: "Low pressure is caused by slower moving air."
• Kaci: "High air pressure is a result of faster moving air."
• Chloe: "The slower the air moves, the more air pressure descreases."
• Chase: "Faster moving air lower air pressure."
