10/17/14 and 10/20/14 Family Trends 2

Date: 10/17/14 and 10/20/14

Class: Physical Science

Periods: W1,2,4 and B2

Outcomes: Students will describe the relationship between how the outer shell electrons determine the characteristics for the alkali, alkaline earth, oxygen group, halogens and noble gases.

Standards: 9-12.P.1.1

Student Needs: Writing time

Assessment Plan: Around-the-Room: What one thing you've learned about each group?

Lesson Outline: What is Archimedes' Principle? How many protons does Sulfur have? How many neutrons does Sulfur-34 have? > Draw outer shell diagrams for C, Si, Sn and Pb. > Video of magnetic liquid oxygen. > So far, we've learned that elements in the same column have the same number of electrons in their outer shells. Today, you're going to continue figuring out what that means for the elements' behavior. The number of protons tells us what element it is but the electrons tell us what they do. > Give directions for the Family Trends paper: 2 pages, double spaced, Times New Roman or Arial 12pt font. Describe properties of the alkali (1), alkaline earth (2), oxygen group (6), halogens (7) and noble gases (8). Focus on physical properties (state, color, shininess, etc.) and chemical properties (how do they react, what do they react with, does it take or release energy). You may need to talk about how specific elements in each group differ from the others. Use websites and the textbook as your resources. Use MLA citation (I know you learned it in English class). > Around-the-Room: What is one thing you've learned about each group? HW: Finish paper. Read 20.1 pgs. 602-606 Why do atoms form bonds?
