2 The place with the highest pressure – above the surface of the Earth or under water.

3 What is under water

4 The location of low pressure when you breathe in

5 What is in your lungs

6 What pressure depends on

7 What is depth?

8 Why it is difficult to drink through a cracked straw

9 What is the air flows in through the crack and keeps the pressure high in the straw

10 Why your ears pop on an airplane.

11 What is that at high altitudes there is less pressure than the pressure in your ears.

12 What will happen if an object displaces a volume of fluid with less weight than the object

13 What is it will sink?

14 Two factors that determine how heavy an object can be and still float

15 What is density and shape?

16 The part of an iceberg that has a weight equal to the buoyant force

17 What is all of it?

18 The person who discovered the principle of buoyant force.

19 Who is Archimedes?

20 How to find the buoyant force

21 What is weight the volume of fluid displaced?

22 The unit of pressure

23 What is a Pascal (Pa)?

24 An area on earth with the least amount of atmospheric pressure

25 What is Mt. Everest?

26 The directions all fluids flow

27 What is from high pressure to low pressure?

28 The pressure caused by all the air in the atmosphere

29 What is atmospheric pressure?

30 The reason why bubbles are round

31 What is air pressure occurs equally in all directions (Pascal’s principle)?

32 The location with greater pressure – 2 meters down in a small pond or 1 meter down in the ocean?

33 What is 2m down in the pond?

34 An object that weighs 2N displaces an amount of water that weighs 2.5 N. Will it sink or float?

35 What is float

36 The pressure exerted on your body by the atmosphere at sea level

37 What is 100,000 Pa?

38 The buoyant force on a 50N object that displaces 10N of fluid

39 What is 10 N?

40 The formula for pressure

41 What is force divided by area or P = F/A?

42 What happens to on object’s density when volume increases and mass stays the same

43 What is density decreases

44 A cube of oak and balsa wood are in water. The balsa cube has more of it above the water. Which is more dense?

45 What is the oak cube?

46 This characteristic allows steel ships to float in water

47 What is their shape?

48 A ship floats in the water when empty. This is what happens if the ship is loaded with styrofoam balls

49 What is the ship will sink lower in the water (increase density)?

50 The explanation for why carbon dioxide bubbles rise in water

51 What is they are less dense?
