NN STEM Day: What is air?

What is air?

Select Earth's atmosphere.

Air is the invisible mixture of gases that make up Earth's atmosphere.

Ar

Select any of the models that respresent the different air molecules.

Select the model that represents a nitrogen gas molecule.Each nitrogen molecule is made from two nitrogen atoms bonded together.

Select the model that represents an oxygen gas molecule.Each oxygen gas molecule is made from two oxygen atoms bonded together.

Select the model that represents a carbon dioxide gas molecule.Each carbon dioxide gas molecule is made from one carbon atom and two oxygen atoms bonded together.

Ar

Which gas makes up about 80% of Earth's atmosphere?

Nitrogen (N2)

Carbon Dioxide (CO2)

Oxygen (O2)

Ar

Yes! Nitrogen Gas (N2) makes up about 80% of Earth's atmosphere.Select one of the nitrogen gas molecules.

Ar

Which gas in the air do our lungs absorb when we breathe in?

Nitrogen (N2)

Carbon Dioxide (CO2)

Oxygen (O2)

Yes! All animals need to breathe in oxygen gas (O2) to live.Oxygen gas makes up about 20% of the atmosphere.

Ar

Select one of the oxygen gas molecules.

The atmosphere also contains a very tiny percentage of other gases, such as methane, water vapor, and carbon dioxide.

Ar

Select the carbon dioxide (CO2) molecule.

Ooh ooh! Studying the composition of the atmosphere (air) is a perfect time to use a pie chart!

Try this activity another way!

Pie charts are useful when comparing parts of a whole.

The Composition of Air

Argon Gas (Ar) 0.93%

Ar

Nitrogen Gas (N2) 78.09%

0.03% Other Gases to include Carbon Dioxide (CO2) and Methane (CH4)

Oxygen Gas (O2) 20.95%

Well done! Select here.

Drag the labels so they correctly show the composition of air on the pie chart. When the labels are correctly placed, a message will appear.

Wonderful work learning about the gas molecules that make up our air!

Now let's investigate... Does air have weight? Does air take up space? Does air exert pressure?

Ar

Large language models use lots and lots of data from the internetto make predictions about what words or phrases might come next.

What might be some pros and cons of using the internet to develop large language models?Type your ideas on the post-it notes.

Cons

Pros

Justin- do we want a pros cons concerning using the internet for generating just text or for all kinds of generative AI?Also, do we want to include a page that disucsses the pros and cons of using generative AI in general (for example, it might help people cheat or cause people to become less creative).

Select the label that corresponds to the most abundant gas in air.

0.03% Other Gases to include Carbon Dioxide (CO2) and Methane (CH4)

Oxygen Gas (O2) 20.95%

Select the label that corresponds to the most third most abundant gas in air. Note: This gas makes up less than 1% of air!

The Composition of Air

Argon Gas (Ar) 0.93%

Ar

Nitrogen Gas (N2) 78.09%

Oxygen Gas (O2) 20.95%

0.03% Other Gases to include Carbon Dioxide (CO2) and Methane (CH4)

Finally, select the label that corresponds to rest of gases that together make up an extremely tiny (but still important) portion of air.

The Composition of Air

Nitrogen Gas (N2) 78.09%

Oxygen Gas (O2) 20.95%

0.03% Other Gases to include Carbon Dioxide (CO2) and Methane (CH4)

Argon Gas (Ar) 0.93%

Notes are saved in all pages where the text field is available

Keep this WITHIN each page where you want to see the note

Text area that can be copied and pasted as many times as necessary within the same page. Notes are kept on all page with the green box during the same session (until the page is closed).

Optional function to be placed IN a page to erase the saved notes and allow to start over on new pages.

Double-click to change the font size value of the text boxes on the same page. The two objects must remain grouped together. (Optional item)
