DONT FORGET TO PHOTOCOPY WORK FROM END OF CHAPTER ONE
 * Act One (Entry Task)**

Examine the two packets at your lab station. One is sugar, two are sweeteners, and one is salt. First, how could you tell the difference by looking at them. Second, with a student blindfolded, see if they can tell the difference. If I can come up with other sweeteners. Can you tell them apart by inspection, by taste, by looking.

IN YOUR NOTEBOOK: 1) First, just by inspection, which do you think is sugar, which is salt, which are the two sweeteners. 2) Why do you think that? 3) Do they "feel" different? 4) Finally, do they taste different.

QUESTION: Can two things with different compositions act similarly? Would it be easy to substitute one thing for another?

I will start a discussion of quantitative measurement and qualitative measurement. What are some things that used to describe, without numbers. (Qualitative) What are some things that used to describe, with numbers (Quantitative) Can things have similar properties but be completely different? They will go to the lab stations to measure the mass of four small objects, and to take properties (evaluation) of them.
 * Act Two (Anticipatory Set, Modelling, Demonstration)**
 * Act Three (Lecture/Notes/Reading)**

What is the mass of 10 pennies? What is the mass of a new pencil? What is the mass of two other things that have a relatively definite response.

Once they have the mass of all four items. What are the properties. How would you describe them. Once the lab is done, we will call them back and evaluate the mass measurements. We will then perform the demonstration of why does ice float in water, but it will sink in alcohol (I could put the water in a bottle and pour it out, see bottom of page 6).
 * Act Four (Lecture/Notes/Reading)**
 * Act Five: (Guided Practice)**

From a photocopy, students will do questions at the end of the chapter that deal with section 1.1
 * Act Six (Independent Practice/Closure)**

Shorter version of plan, under edit 1) On board, put pass your paper forward 2) Explain how groups will work 3) Go to lab station, read paper 4) Explain that Entry tasks are observed, not turned in 5) Perform Entry Task 6) Discuss notebook requirements 7) Notes-qualitative vs quantitative "Guess the item, any allergies" 8) How do you use a triple beam balance a) mass of 10 pennies b) mass of a pen 9) Does ice float in water? 10) photocopy from 1.1
