Science+Week+2+(8-22+to+8-26)


 * Matter and change **
 * 1) Identify **chemical reactions** in terms of reactants and products
 * 2) List factors affecting the ** rate of reactions **

Monday, August 22th (Chemical Reactions; Chemistry/Ch 2/Sec 1/pg 36)
To Dos:
 * 1) Compare pennies: Why is this one brown and dull and this one is shiny?
 * 2) Because the oxygen from the air reacted to the copper on the penny forming a copper oxide layer...
 * 3) Penny & Hot Sauce Experiment
 * 4) Today we're gonna talk about Physical Changes and Chemical Changes...
 * 5) Give definition!!...Physical Change: A change that effects only the size and shape of a substance or whether it becomes a liquid, solid, or gas...
 * 6) Can someone give me an example of a Physical Change: Ice melting into water...
 * 7) What happens if __ holds this ice cube throughout class?
 * 8) Why is Ice melting into water a good example of a physical change? Because it's still water; it only changed from a solid to a liquid...
 * 9) What then is a chemical change?
 * 10) Chemical Change: A change that produces new substances that have properties different from the original substances...
 * 11) What is an example of a chemical change that we've already talked about? Oxygen mixing with the copper to form a copper oxide...
 * 12) Why is that a good example of a chemical change? Because the copper from the penny is changing because of a reaction to the oxygen...
 * 13) Define: Chemical Reaction: A process that produces chemical change...
 * 14) Give me an example of a Chemical Reaction: The hot sauce reacting with the copper oxide...
 * 15) Tape "Before" and "After" Pennies into Science Journal

Tuesday, August 23rd (Reactants and Products; Chemistry/Ch 2/Sec 1/pg 38)
To Dos:
 * 1) Review: What is an example of a physical change? / What is an example of a chemical change? / How is a physical change different from a chemical change? / What is an example of a chemical reaction?
 * 2) Read page 38, "Chemical Equations" and in your Science Journal define Reactants and Products
 * 3) What is a Reactant?
 * 4) Reactant: Substances that exist before a chemical reaction begins
 * 5) What is a Product?
 * 6) Product: The substances that form as a result of a chemical reaction
 * 7) Experiment: What do you think will happen when I mix baking soda and vinegar?
 * 8) In this experiment what are the reactors? (Baking Soda & Vinegar)
 * 9) What are the products? (Gas & White Solid)

Wednesday, August 24th (Rates of Reactions; Chemistry/Ch 2/Sec 2/pg 46)
To Dos: Make Copies of Chemical Reactions Key Terms Worksheet (Chemistry/Ch 2/pg 22)
 * 1) Review: In our baking soda experiment what was one of the reactors? / What was the other reactor? / What was one of the products? / What was the other product? / Give me a definition of a reactant / Give me the definition of a product
 * 2) Complete the Key Terms Worksheet by reviewing pages 46-52
 * 3) Review the Key Terms Worksheet as a class
 * 4) Complete notecards to study for Key Terms quiz

Thursday, August 25th
To Dos:
 * 1) Review factors 1 & 2 affecting rates of reactions

Friday, August 26th (Chapter Test)
To Dos:
 * 1) Review factors 3 & 4 affecting rates of reactions
