1. UNIT 1 Matter Day 14 Tuesday, September 19, 2017
Atoms
8th Grade Science

2. Unit 1 Matter Day 14 Focus: Atoms 9/19/17
Pick up the 2 sheets of element cards and the ½ sheets on atom diagrams from the front lab table.
Elements of the Day
2. Open a textbook to pages On your element cards, fill in the following information for B (Boron):
Atomic number
Element name
Atomic mass
# of protons, neutrons, electrons
Solid, liquid or gas (use the key in the book)

4. Let’s organize things in your notebook.
Please quickly do the following:
Place the 2 sheets of element cards in the front or back pocket of your binder. Don’t lose them. We will work on them each day, and they are for a project in a few days.
Tape the Bohr model practice sheet onto page 13 but leave room to answer the E.Q. in a minute.
Tape the Bohr/Lewis diagram sheet onto page 14. Make sure you can fold it out to see and work on both sides of it. CFA’s on p. 12.

5. Turn and talk: Discuss with your group members and answer yesterday’s E.Q. Stay on topic and hurry!

6. Plan for the Day E.Q. Review homework
Lesson on atom drawings-Bohr Diagrams of the Atom
a. PowerPoint and explanation
b. Practice
4. Wrap-up

7. Homework: Draw Bohr diagram for Boron on your element card.
Finish the Bohr diagrams on the Bohr Diagram worksheet for hmwk tonight.
Flash cards due tomorrow.
You will need to start bringing your own colored pencils Friday.

8. Essential Question –
How is the arrangement of electrons in the atom related to an element’s location on the Periodic Table?

9. Let’s learn how to draw diagrams of the atom – Turn to page 14 in your binder. There are a few notes to take.

10. What does the atom have to do with the periodic table of the elements?
If time permits, we’ll conduct formative assessment on the content from today.
