Intro to the Periodic Table Periodic Trends Graphing Activity
Evaluation/ Assessment Objective Today I will be able to: Explain why different families on the periodic table have similar properties Evaluation/ Assessment Informal assessment – Listening to group interactions and discussions as they color and complete the practice sheet Formal Assessment – Analyzing student responses to the exit ticket and practice worksheet
Lesson Sequence Engage: Warm – Up Engage: Coloring the Periodic Table Explain: Introduction to the periodic table notes Elaborate: Periodic Table WS Evaluate: Exit ticket
Warm - Up What is the most stable family on the periodic table? Why is this family the most stable? What families contain the most reactive elements on the periodic table? Take a look at Electrons Quiz 1. Ms. Ose will re-collect it in a few minutes. Please ask Ms. Ose for help if you have any questions!
Warm - Up Gather your colored pencils and take out the coloring the periodic table worksheet so we can finish the coloring the periodic table activity Watch the video clip that Ms. Ose plays and think about these questions: What families contain the most reactive elements on the periodic table? Why are they the most reactive elements? http://www.youtube.com/watch?v=HvVUtpdK7xw
Objective Today I will be able to: Explain why different families on the periodic table have similar properties

Finish the Coloring the Periodic Table Activity from Last Week 10 more minutes to work on the assignment
Intro to the Periodic Table Notes
What are the names of the columns and rows on the periodic table?
Periods – horizontal rows - There are 7 periods Families – columns Families have similar properties - There are 18 families Periods – horizontal rows - There are 7 periods
There are two ways to number the periodic table:
What is the difference between a metal and a nonmetal?
Metals vs. Nonmetals Found to the left of the “zig-zag” line on the Periodic Table Properties of Metals - Luster – shine - Malleable – can be hammered into sheets - Ductile – can be drawn into a wire - Good conductors – allow heat and electricity to pass through Non-metals and noble gases are found to the right of the “zig-zag” line Their properties are the opposite of metals
Families on the periodic table have similar properties Example: Alkali Metals Soft Cut with a knife Highly Reactive
Why do the families of elements have similar properties?
Valence Electrons Elements in the same family have the same number of valence electrons Impacts how they bond
Metalloids (Semi-Metals) Most of the elements touching the zig-zag line B, Si, Ge, As, Sb, Te, and At They have similar properties of metals and some properties of non-metals
Reading the Periodic Table Practice Complete the WS. Ms. Ose will collect it as a classwork grade.
Exit Ticket What is the most stable family on the periodic table? Why is this family the most stable? In addition to the alkali metals, what other family is also highly reactive? Mol Monday #1 How many moles of Au are in 2.24 x 1024 atoms of Au?
