Tuesday 9/29

Journal:

1. Make a simple drawing of a Boron (B) atom.
2. What limitations or flaws are there to this type of model?

Today we reviewed the strengths and limitations of our model of the atom and came up with a chart for our notes like this (copy this into your notes if you weren't here):

STRENGTHS (THINGS THAT ARE ACCURATE):

• shows charges
• shows energy levels of e-
• shows protons, electrons, and neutrons and relative locations of each

LIMITATIONS (INACCURACIES)

• size and scale of atom not appropriately shown
• e-s aren't moving

Then we played a game outside making "human atoms" and identifying the correct number and location of the subatomic particles of various elements (no makeup necessary for this).

HW:  none

Monday 9/28

Journal:

1. What “subatomic particles” are atoms made of? What are the charges of each? Where in the atom are each of the subatomic particles found?
2. How do we know atoms exist if we cannot see them?

Today we handed in the Atom or Molecule?/Making Molecules assignment, then took notes and practiced making models of atoms. Please get the notes from a classmate and the assignment from me.

HW: none

Friday 9/25

Journal:

We watched this video clip and took notes for the journal today.

Today we finished the atom/molecule notes (use this PowerPoint, this notes outline, this worksheet, and the periodic table).

Then we went over the assignment I assigned on Wednesday (Atom or Molecule? and Making Molecules) and assigned part C of Atom or Molecule? as homework.

HW:  Part C of Atom or Molecule? 

Thursday 9/24

Journal:

What is the difference between an atom and a molecule?

I handed out midterm progress reports today to be signed. It is 15 extra credit points if you bring it back by next Tuesday 9/29.

We then finished the notes from yesterday using this PowerPoint, and this notes outline (also download pg 2).

HW:  none

Wednesday 9/23

Journal:  What is the atomic number of Iron? Chemical symbol? How many protons and electrons?

Today we did these two worksheets:  Atom or Molecule? and Making Molecules.

Whatever you didn't finish is homework.

HW:  anything left on worksheets

Tuesday 9/22

Journal:

Use 4 of the 5 journal minutes to study your vocab words. In the last minute, write about one of the words. Did you know it before this class? What do you know about it? Can you identify any Latin roots? How can you remember what it means?

We went over the article "Democritus' Idea of an Atom" and the Pre-/Post-Reading activity that accompanied it, then turned it in.

We then started notes about matter. You will need this powerpoint, this notes outline plus side 2 of the outline, and this periodic table to complete the notes. We only got about halfway through; we will finish tomorrow.

HW:  none

Monday 9/21

Journal:

Write a paragraph explaining what you know about:

1. matter
2. atoms
3. molecules

Tell how they’re different and how they’re related.

I gave you the class today to define vocabulary for the "All About Matter" unit. Write all words and definitions on the "magic weave" we made in class Thursday. Come see me if you need one. The words to define are on the new I can statements.

HW: Read the article "Democritus' Idea of an Atom" (that's it, don't do the review or anything else, just read it),
