Scroll down to see the date you want. Lessons often have two dates because D & F block study the same material, but the classes do not meet on the same date. Clicking on "Lesson 1," for example, will take you to a view that shows only that lesson, but you can just as well view the material on this page.

F block: same as D block
ASSIGNMENT(S):
D block: (1) none
F block: same as D block
Lesson C Family Trends
(Feb 29)
OBJECTIVE(S)
(8.2) Understands how elements are arranged in the periodic table, and how this arrangement shows repeating patterns among elements with similar properties (e.g. numbers of protons, neutrons, and electrons; relation between atomic number and atomic mass) [Describe and explain the Periodic Table as a method of classifying elements and its use in predicting properties of elements] (8.2.4) Give properties of 5 major families of the periodic table: Hydrogen, Alkali Metals, Alkaline earth Metals, Halogens, and Nobel gases
LESSON(S)
D block: Students work, with guidance, on assignment: Element Families in the periodic table.
F block: same as D block
ASSIGNMENT(S):
D block: Students complete "Families in the Periodic Table" (click on link to download worksheet)
F block: same as D block
Lesson D Period Table Trends
(Mar 3/4)
OBJECTIVE(S)
"Real" science simulationse measurements (data) to identify patterns in periodicity.
LESSON(S)
B block: See block B section under "classes" at the top of the page.
D block: Give students data table of elements in alphabetical order. Using "large" graph paper (we're using 11 x 17 inch paper) have students select a property that reveals patterns in the table. Clear patterns are visible from choices including: atomic radii, electronegativity, ionization energy, and mass. Students graph one trait for a selected group of elements; we'll use elements no. 1 - 54. Students graph data, using fine points. We will discuss the trends in class next period. [I did not collect "Element Families" handout; we will review that next period with the graph data.]
F block: same as D block
ASSIGNMENT(S):
B block: not here
D block: Students make a graph of the specific data assigned in class. Graphs will be due on Friday this week for both D and F block (to give you extra time). Students handing in graph on Wednesday (F block) or Thursday (D block) will receive extra credit. Remember that a graph must have:
• labels and units on both axes like "Atomic mass (a.m.u.)" or "atomic radii (angstroms)"
• plotted neatly
• scale should be even increments; pieces should all be same size.
• data should be spread over at least 3/4 of the axis in both the x and the y direction.
F block: same as D block
Lesson B History of Chemistry
(Feb 27/28)
OBJECTIVE(S)

LESSON(S)
B block: (1) Explain "Chemistry History" powerpoint to students.
D block: same as B block
F block: same as B block
ASSIGNMENT(S):
B block: Complete B_ChemHistory_name
D block: Complete D_ChemHistory_name
F block: Complete F_ChemHistory_name
Lesson A Atom structure reviw
(Feb 25/26)
OBJECTIVE(S)
(8) Knows that matter is made up of tiny particles called atoms, and different arrangements of atoms into groups compose all substances; (8.D) Understands the subatomic particles makeup of every atom including name, charge, location and relative mass of protons, neutrons and electrons; (8.D.2) Be able to solve for name, Standard Atomic Notation, number of protons, neutrons and electrons for first 20 elements; (8.1) Understands the “Particle model of Matter” 8.2.1 Be able to draw Bohr-Rutherford diagrams for the first 20 elements and explain increase in number of rings/orbits /shells with each row/period and same number of valence electrons in each column/family; 8.2 Understands how elements are arranged in the periodic table, and how this arrangement shows repeating patterns among elements with similar properties (e.g. numbers of protons, neutrons, and electrons; relation between atomic number and atomic mass) [Describe and explain the Periodic Table as a method of classifying elements and its use in predicting properties of elements]
