Grade 8: Week of January 30th to February 3rd

Grade 8s did very well on their Property of Matter Tests! They will receive them back on Tuesday due to the amount of students needing to still take the test.

We will begin our chapter on the Periodic table. Students will learn how to interpret this table based on the families, valence electrons in the outer shell, and amount of electron shells. I will teach students using power points and then they will practice in class and have homework on the day's lesson. Students may go to the website www.middleschoolscience.com, click on the Chemistry link and then scroll down to the Periodic Table for resources used in class. Under the periodic section, the following power point presentations and interactive sites are useful:

• PPT: Coloring the Periodic Table Families

• PPT: Determining Shells and Valence Electrons

• PPT: How to Draw Bohr Diagrams

• PPT: How to Draw Lewis Structures

  • The Visual Elements Periodic Table: Wonderful graphics!!! Provides chemical data for each element.

    Homework for the week is as follows:

    Monday: finish the Property of Matter lab

    Tuesday: Pg. 265 Reflect; find the atomic number, isotope, and symbol of Sodium, Oxygen, Hydrogen, Carbon, Mercury, Phosphorus, and Lead.

    Wednesday: Pg. 265 Review; Draw the electron shells and nucleus of Helium, Magnesium, Neon, and Calcium

    Thursday: Pg. 272 Review, Reflect #1, Draw a Lewis Dot Diagram of Lithium, Titanium, Nitrogen, Argon, and Calcium
