13. Atoms and Molecules in Air Oxygen molecules (O2) are made of 2 oxygen atoms Nitrogen molecules (N2) are made of 2 nitrogen atoms Water molecules (H2O) are made of 2 hydrogen and 1 oxygen atom Carbon dioxide molecules (CO2) are made of 1 carbon and 2 oxygen atoms 13

14. Three Facts about Atoms 1. Atoms last forever (except in nuclear changes). 2. Atoms make up the mass of all materials. 3. Atoms are bonded to other atoms in molecules. 14

15. Apply the Three Facts About Atoms to Air 1. Atoms last forever (except in nuclear changes). a. Will the carbon atoms that exist today in CO2 still be carbon atoms in a million years? b. Will the CO2 molecules that exist today still be CO2 molecules in a million years? 15

16. Apply the Three Facts About Atoms to Air 2. Atoms make up the mass of all materials. a. Does air have mass? 16

17. Apply the Three Facts About Atoms to Air 3. Atoms are bonded to other atoms in molecules. a. What are some important atoms in air? b. What are some important molecules in air? 17

18. Check Your Understanding Do you think that people are made of atoms? Do the three facts about atoms apply to the atoms that we are made of? Do you think that ethanol is made of atoms? Do the three facts about atoms apply to the atoms that ethanol is made of? Do you think that flames contain atoms? Do the three facts about atoms apply to the atoms in flames? 18

19. Learning Tracking Tool For the activity Zooming Into Air, discuss with your classmates what you figured out will help you to answer the unit driving question, what happens when ethanol burns? Record your ideas in the column What We Figured Out. Discuss questions you now have related to the unit driving question and record them in the column What We are Asking Now. 19

20. Exit Ticket Conclusions What are three facts about atoms? Predictions Why do we study atoms and molecules even though they are too small to see? 20
