 * Act One (Entry Task)**

To start off the task, students will have a small wrapped box, and they will have something "hidden" inside. They will attempt to determine size? shape? amount? composition? of the box. If I cannot think of a box, I can use empty soda cans. Perfect! Things I would want to include are a) Spheres from the ball and stick models b) Coins c) paper clips d) rice e) play doh f) Whatever else I can think of

1) Try and figure out the size, shape, number, and composition in each can. 2) How did you make your observations. . . Once that is done, I will pass back the assessments done that previous Friday. We will go over them, and see if there are any errors or things that needed fixing. Start off by discussing what they got for the Entry Task. Create a table of things on the board. That is how we discovered the atom. Even though we could not see it, we determined what it did and how it acted, and what is does or relates to others.
 * ACT ONE POINT FIVE**
 * Act Two (Anticipatory Set, Modelling, Demonstration)**

Well, I start off with a volunteer and a piece of aluminum foil. Rip that in half. Is it still Aluminum? Rip that in half. Is it still Al? keep going until you cannot go anymore? This is how the Greeks did their theoretical observations. . From there, we talk about the four "elements" as presented by the Greeks. (Fire/Earth/Water/Air) Kinda makes sense when you think about it. (pg 50 in book) or. Can you "in theory" relate everything to one of those four. Hot is half air half fire Wet is half air half water Cold is half water half earth dry is half fire half earth . Things that can be burned have fire in them, they just have to be let out Liquids that evaporate half air in them that takes over Liquids have water in them . . Discuss Law of Conservation of matter, and how it applies. Antoine Lavoisier. . Go to lab station, do quick demo. Weigh baking soda and vinegar apart. Put them together, does it still weigh the same (vinegar in balloon, baking soda in flask)
 * Act Three (Lecture/Notes/Reading)**

Afterwards, discuss what we found, see if verify . Dalton's atomic theory, as presented on the board. 1) All matter is made of atoms 2) Atoms are indestructible, and cannot be divided into smaller particles 3) All atoms of one element are EXACTLY alike, but are different from atoms of other elemetns. Discuss what does this mean?
 * Act Four (Lecture/Notes/Reading)**
 * Act Four (Lecture/Notes/Reading)**
 * Act Five: (Guided Practice)**
 * Act Five: (Guided Practice)**

I will give Check For Understanding questions on the whiteboard to see if they "grasp" Dalton's theory, and Proust' theory.

They will do questions given to them on a practice sheet that stem from the end of the chapter.
 * Act Six: (Independent Practice/Closure)**

-- What did we actually do?
