Homework: Atmosphere Importance HW

Monday April 1: Hand in your homework.

1. What do you think the earth is made of? Explain! You should have MORE THAN ONE idea!

2. Do you know what the 4 spheres are? If so, list them.Date Table of Contents Page

Earth Science and Weather!!!

This Week’s ObjectivesWe will learn about the four “spheres,” or

systems in our earth.

We will learn how the spheres interact with each other.

We will learn how we can see these spheres in our everyday lives.

For these notes, whatever is written in red, you write too.

1) The earth is mostly rock.2) 75% of its surface is covered by a thin layer of water.3) The entire planet is surrounded by a thin layer of gas.4) The earth can support life.

Review ActivityI will read off a description of a sphereYour table has cards to show what sphere I’m

describingL = lithosphereH= hydrosphereA = atmosphereB = biosphere

I will give you 30 seconds to think about which sphere it belongs to

When I say “show me,” each group will hold up its answers. Don’t reveal your answers early.

What Sphere Do I Belong To? I am the Nile

River and I flow through North Africa.

River and I flow through North Africa.

I belong to the hydrosphere!

Nile River is hydrosphere because it is water.

What Sphere Do I Belong To? I am the Mojave

Desert, home to plants the Joshua Tree and cities like Las Vegas!

I belong to the biosphere!

Mojave Desert is biosphere because of people, plants, and animals (life).

What Sphere Do I Belong To? I am the Himalaya

Mountain Range in Asia, home to Mount Everest!

What Sphere Do I Belong To? I am the Himalaya

Mountain Range in Asia, home to Mount Everest!

I belong to the lithosphere!

Himalaya Mt Range is lithosphere because of rocks.

What Sphere Do I Belong To? I am a place

where satellites can orbit, bringing you TV from all over the world!

What Sphere Do I Belong To? I am a place where

Exit SlipClear everything off of your table. Close

lab books and put them on the floor.

NO TALKING, at all. If you have a question raise your hand SILENTLY and wait for the teacher.

If it is multiple choice, you can just write the letter of the answer.

Question 22. Examine the diagram. What sphere is this diagram showing?a) Biosphereb) Lithospherec) Atmosphered) Hydrosphere

Question 33. When you are using your respiratory system, what is the main sphere you are working with?a) Biosphereb) Lithospherec) Atmosphered) Hydrosphere

Question 44. Draw a picture to represent the lithosphere. Then write a sentence to explain why your picture represents the lithosphere.

Tuesday April 2 or Wednesday April 3

1. List the 4 spheres.2. What sphere do you think Antarctica is part of and why?3. Your large intestine absorbs ______, which is a part of the _____-sphere.Date Table of Contents Page4-2-13 or 4-3-13

Today’s PlanWatch a short video about the Earth’s four

spheres to review what we learned on Monday.

Read The Four Spheres and answer questions about the reading to learn more about the Earth.

Create a comic about the Earth’s 4 spheres to interact with the content.

Complete The 4 Spheres Homework before next class period to reinforce what you’ve learned today.

The Four Spheres of the Earth Reading

Biosphere ComicPick an organism (any kind of life-form)

Examples: Mosquito, your little brother/sister, a pigeon

Make a comic of how that organism interacts with our four spheres

See example (next slide)

Sphere ComicBe sure to include each sphere

(lithosphere, hydrosphere, atmosphere, and biosphere)

Use all six comic boxes—that means you will have to use some of the spheres more than once

Use a combination of words and picturesBe sure to color your comic

Thurs April 4 or Friday April 5Hand in your homework.1. What is the atmosphere?2. What do you think would happen

if our earth did not have an atmosphere?

3. Why do YOU need the atmosphere?Date Table of

Atmosphere

Things you’ll need to know for your exit slip…Understand why the atmosphere is

important for life on EarthKnow what gases make up Earth’s

atmosphereUnderstand the relationship between

altitude and air densityUnderstand where air pressure is highest

and lowest and why

Remember, if a word is written in red, write it in your lab book.

Atmosphere Notes!

Atmosphere questionsWhat is the main gas in the

atmosphere?What type of gas do we need?What type of gas do we release?What type of gas do plants

release?What type of gas do plants need?

What Makes the Atmosphere?

~78% Nitrogen gas

~21% Oxygen gas

Some aerosols

(suspended liquids and

solids)

Why is the atmosphere important?It helps living things

SURVIVE!It gives oxygen

for breathing.It traps heat for

warmth.It protects Earth

from radiation and meteors.

It acts like earth’s bodyguard!

What’s the difference between mass and weight?

MassThis is the amount

of matter in something

Mass always stays the same

WeightThis is the measure

of the force of gravity acting on an object

Weight changes when gravity changes

Air pressure:Air Pressure is the weight of the

atmosphere pressing down on the earth.Review: What extra “oomph” or

measurement does weight have?

Altitude can changeAltitude: how

high you are from sea level

If you hike up a mountain, your altitude increases

As you climb a mountain…Does the air pressure on

you INCREASE or DECREASE?

Thumbs UP = IncreaseThumbs DOWN = DecreaseBe prepared to share your

answer! As you climb a mountain,

air pressure decreases because there is less gravitational pull on air molecules.

As you climb a mountain, air pressure decreases because there is less gravitational pull on air molecules.

Air pressure can changeAs altitude increases, the air

pressure decreases.This is because there is less air above

you to push down on you.

Think of it this way…

Air Pressure and Weather

Air Pressure and WeatherHigh pressure areas are usually sunny

High pressure =

Low Pressure areas are usually cloudy/rainy

Low pressure =

Air Pressure and WeatherYou're well familiar with our "H" and "L" designations on

weather maps for areas of high and low pressure, but what do they mean in regards to what weather's coming? High pressure situations are generally associated with fair, sunny weather. As high pressure is an area of sinking air, and air tends to dry out as it sinks, leaving sunny skies.

Low pressure areas are generally cloudy/rainy areas -- where strong areas of low pressure bring our stormiest weather. That's because it's an area of rising air, and as air rises, it condenses into clouds and rain. Air moves from higher pressure to lower pressure, so if you have a high and a low nearby, it can be windy as air rushes between the two.

From: http://www.komonews.com/weather/faq/4347756.html

Which states have sunny weather? Which states have rainy weather?

Density ReviewDensity is the mass of a material in a given

volume.Density = Mass/Volume

Remember sinking and floating? Objects that are more dense sink. Objects that are less dense float.

I’m less dense!I’m

more dense!

Altitude and DensityAs you climb up a mountain…

Does the air get MORE DENSE or LESS DENSE?

Thumbs UP = More DenseThumbs DOWN = Less DenseBe able to explain your answer.As you go up, the air gets less dense

because objects with greater density sink and objects with less density rise to the top.

Altitude and DensityAs altitude increases, air density

decreases.Remember, less air pressure = less

forces pushing air particles together.

Layers of the atmosphere:TroposphereStratosphereMesosphereThermosphere*Each layer has its

own distinct characteristics:- Temperature- Composition

Most weather happens here!

Bill Nye Atmosphere VideoBefore you watch the video, preview the
