• You will be given a new Catalyst sheet

1. Make a prediction: What do you think will happen and

why?2. After watching the demo,

what happened, and why do you think it happened?

Catalyst

What does this demo suggest about whether air pressure only pushes down, or whether it pushes in other directions, too?

Pressure is the force over a given area.

Water pressure is the force exerted on

something by water molecules

Air pressure is the force exerted on something by the

particles that make up air.

Both water pressure and air pressure are related to height

Both water pressure and air pressure are related to height

Both water pressure and air pressure are also related to density

Both water pressure and air pressure are also related to density

Since we know that density is related to temperature, we must also know that

pressure is related to temperature too!

Homework

- Final Infographic due Wednesday (period 2) or Thursday (periods 1, 7, and 8)

Your Infographic must include…

• A good, clear definition of pressure• At least one graphic with accompanying text that

shows and describes the relationship between density and pressure

• At least one graphic with accompanying text that shows and describes the relationship between pressure and water depth

• At least one graphic with accompanying text that shows and describes the relationship between pressure and weather patterns

1. What is air pressure?2. How does increasing the density

of a gas affect its pressure?3. What is altitude?4. As altitude increases, how does

air pressure change? How does density change?
