Visualizing Earth's Atmosphere

Each globe costs $7.25. If each person here got one, how much would our total cost be?

Assuming all 13 people are here

Instead of making a 3D version of the atmosphere, we are going to draw it out

But first we need to review a little math so that we can draw it correctly

  $0.9\ \div\ 3$  

Open Ended

 $0.9\div3=$  

 $0.24\div4$  

 $0.032\div8=$  

 $1.5\div5=$  

1.05 $\div5=$  

 $3.015\div5=$  

Why did we review this skill?

To be able to determine the needed dimensions of your 2D atmosphere!

The chart paper is 60.96 cm in length. If we want to divide it into 5 sections, how large would each section be?

60.96 $\div$  5

However, our atmosphere layers will not be the same size so we need to do a little more math

Let's practice a little more before we do those computations

6.72 $\div$  3

Multiple Choice

 $6.72\div3$  =

• 2.1

• 2.2

• 2.24

• 2.024

 $6.372\div6$  

How is this one different from the problem we just did?

What happens when things start to look a little more different like 2.6 $\div$  4

 $1.7\div2$  

 $17\div4$  

Open Ended

 $22\div8$  

Multiple Choice

 $7.7\div4$  

• 2

• 1.9

• 1.92

• 1.925

Okay, I want to see what you can do with this

Take 10 minutes to work on your own while I get the materials ready for our atmosphere project!

Alright, now comes our math

We want to make this to scale, meaning the size on paper resembles the size in real life

Like a blueprint

I need you to figure out the following:

•  $0.01567\div10$  

•  $0.0627\div40$  

•  $0.07839\div50$  

•  $0.627\div400$  

•  $0.1567\div100$  

Did you get something like 0.001567?

That's our scale factor! Meaning that every 0.001567 of an inch on our paper represents 1 km in real life!

Your atmosphere's will need the following

• Troposphere:0.02 inches thick

• Stratosphere: 0.06 inches

• Mesosphere: 0.08 inches thick

• Thermosphere: 0.6 inches thick

• Exosphere: 0.16 inches thick
