Lesson: Friday 9/4
- 1. Launch Drop off you lab notebook on the shelf. Take out your notes/foldable and SILENTLY* study for the quiz. Quiz topics include: What is chemistry? What is matter? What is matter made of? What is the atom made of? What instruments/units of measurement are used to describe matter? *Warning: As soon a people begin talking, we will end study time and immediately begin the quiz. Use this time wisely!
- 2. How is the atom structured? Mr. Heffner Chemistry 9/4/09
- 3. What is the atom made of? 3 subatomic particles Proton = +1 charge, 1amu Neutron = no charge, 1amu Electron = -1 charge, ~0amu + _ 0
- 4. How is the atom structured? The atom has two parts Nucleus In the center of the atom Location of protons and neutrons Rings On the outside of the atom Location of electrons aka “electron cloud”
- 5. How is the atom structured? Nucleus Rings Protons Nuetrons Electrons 0 0 0 0
- 6. Summary Two parts of the atom Nucleus – protons and neutrons Center Rings – electrons Outside, around the nuclues 0 0 0 0
- 7. Practice Questions None today!
- 8. Dead White Guy Activity Read all 5 descriptions of the “Dead White Guys” Fill in the “Dead White Guys” graphic organizer Place into Handouts section of binder
- 9. Exit Slip What are the two parts of the atom? Protons are found in the Isotope Nucleus Rings Electron cloud Where are neutrons found?
- 10. Exit Slip An electron has a 1- charge 1+ charge 2+ charge no charge Draw a quick sketch of the atom and label the two parts.
- 11. Exit Slip True or False (and if false, re-write the statement so that it is true). “Electrons have virtually no mass and are negatively charged.”
- 12. Homework Make sure you binder is put together just in case we have a random “Binder Check” next week Remember: one person can let the whole team down!
