Charge!

In case you missed it, here are the two videos from class: (if you were in class but did not take notes, re-watch the videos and take the notes described below.)
1. Just How Small is an Atom?  in your SJ, copy & illustrate  at least three of the comparisons that are given. {example: If all the atoms in a grapefruit were the size of a blueberry, the grapefruit would be as big as the earth.}

2. How Big is an Atom?  As you watch this video, make a list in your SJ of all the steps  down-sizing, starting with the 10 meter maple tree to the incredibly small neutrino particle. 12 min.

3. How Protons, Electrons and Neutrons Were Discovered:  Take notes in your SJ. Include the names of the scientists, the discovery and  the year of the discovery, and an illustration of the experiment. 14 min.

4. Atomic Structure: yes on notes.  12 minutes.

5. Build an Atom: pHet simulation: http://phet.colorado.edu/sims/html/build-an-atom/latest/build-an-atom_en.html

Build the first 10 elements (stable and neutral).(hydrogen through neon) and learn their symbols (draw 5 different atoms in your SJ)  Try out both orbital and cloud models. And play the games (figure out for yourself what is an ion, stable, neutral, etc.) 

6. MEMORIZE the first 20 elements, in order! and their symbols.  REQUIRED!

So there you go.  Your science journal should have lots of new stuff in it, and you should make sure it has a title page for chapter 18 as well as a table of contents.  Draw a lot (but not random stuff!)
