Welcome to Quarter 2 Fresh start Day #2

REMIND 101 Text the code @mrswardssc to 980-734-3912 Updates and important reminders

“What’s Up in the Air?” Hands-On Inquiry Activity (25 minutes)

Review from yesterday (20 minutes)

Goldilocks Principle (5 minutes)

Guided Notes (20 minutes)

Atmosphere Videos (5 minutes)

Exit Ticket (5 minutes)

PLEASE FOLLOW INSTRUCTIONS CLOSELY.

For this exercise, you will use: Clear Jars Dried Brown Beans Dried Black Beans Dried Red Beans

Think back to our DO NOW…. On the Bottom of Page 3, record the following data:

78% of Earth’s Atmosphere is comprised of NITROGEN

21% of Earth’s Atmosphere is comprised of OXYGEN

1% of the Earth’s Atmosphere is comprised of OTHER GASSES (Argon, Carbon Dioxide, Water Vapor, etc.)

Each of the beans will represent a gas found in our atmosphere.

78 Brown Beans will represent Nitrogen in your jar

21 Black Beans will represent Oxygen in your jar

1 Red Bean will represent all the other gasses.

Density: The mass per unit of volume

Altitude: The distance above sea level when discussing the atmosphere

Air pressure:

Air has mass, because it is made up of molecules of gas (Nitrogen, Oxygen, etc.)

Gravity exerts a force on these molecules, pulling them closer to the surface of the Earth and holding them there

Altitude Air Pressure

Density of Air

Molecules

Why?

Sea Level (close to the ground)

High Molecules are tight together

Gravity is pulling the molecules of air closer to the surface of the Earth

On top of Mt. Mitchell (highest peak in NC)

A little bit lower Molecules aren’t as tight together

Moving away from the Earth’s surface, gravitational pull isn’t as strong

Mt. Everest (highest peak on Earth)

Low (not enough air to breathe)

Molecules are far apart

Less gravitational pull

Thermosphere (near the edge of space)

Close to non-existent

So far apart it they really aren’t even there

Less gravitational pull

Use the diagram to the right to describe the difference in temperature and pressure between the top and the bottom of the mountain. Defend your claim by using the terms density, altitude, and molecule.
