Lesson Sequence: Day 1
Introduction to chemical nomenclature, discrete number concept, LAB 1.
- Class problem/discussion - (Use any compounds you wish. I used the following.)
- Discuss meaning of the formulas.
- Discuss meaning of "dozen."
- Assign two problems. Start in class, finish at home.
- How many molecules will you have of each compound above if you
are given -
- 1 dozen
- 5 dozen
- 10 dozen
- 0.5 dozen
- X dozen
- How many dozens of atoms of each kind will there be for each
compound given the number of molecules in Question "a"
above? (Have students make a table to simplify the
- Do LAB 1.
- Students to supply info for Hyphothesis and Test. For NaCl, 5.8gm/100mL=58gm/L which is a 1.0 Molar solution.
- In these labs we approximate a molar solution by using 100 mL water, instead of 100 mL final solution, thereby ignoring the volume contributed by the salts.
- finish "dozens" problem.
- finish LAB 1 write-up.
- read sections 1 (Nature of Matter) and 2 (Composition of Matter) in chapter
3 of Biology,
Miller-Levine (Prentice-Hall), and do the review questions at the end of each section.
