• Lesson:1. Go over BR2. Stations Lab3. Go over Lab, HW questions from last night?4. Practice Density Problems (p 48: 1-3)5. Go over density problems

• HW: DENSITY PROBLEMS P. 61 # 23-26

• NO SCHOOL THURSDAY

MATTER Unit Friday, September 30

• Objective: SWBAT compare and contrast physical and chemical properties and changes.

• BR: 1. What is a physical property; a chemical property?• Lesson:

1. Discovery Ed Video Lesson on Physical vs Chemical Properties

2. Notes on Chemical/Physical Properties

• HW: – DENSITY PROBLEMS P. 61 # 23-26 (From Wed-quiz Mon)– page 58 # 1, 2, 7

MATTER Unit Monday, October 3

• Objective: SWBAT measure and calculate the density of a liquid, regular solid and irregular solid using proper SI units.

• BR: 1. What is density. 2. Is density a chemical or physical property? 3. What units do we use to report density?

• LESSON1. Density Quiz2. Go over BR and how to use the water displacement method3. Density of a solid/liquid Lab

1. Watch your precision and sig figs in all calculations!!!2. Remember – when do you need to use water displacement to find

volume? When do you NOT?

• HW: finish lab (there is a back)

MATTER UnitTuesday, October 4

• Objective: SWBAT create a mass-volume graph for values collected in the lab.

• BR: What is the formula for calculating density? What are the two units we can use for density?

• Lesson:1. Discuss density lab2. Penny Lab

• HW: Finish the graph

MATTER UnitWednesday, October 5

• Objective: SWBAT interpolate and extrapolate data about the density of pennies pre- and post -1982.

• BR: Draw the set up for a graph with mass on the y axis and volume on the x axis? What is the slope of this line?

• Lesson:1. Make Graph(s)2. Finish Penny Lab

• HW: Finish Lab

MATTER Unit Thursday, October 6

• Objective: SWBAT identify and list examples of chemical and physical properties and changes.

• BR: What is the difference between a physical change and a physical property. Give an example of each.

• Lesson:1. Notes on Physical/Chemical Properties and

changes (2nd period- present posters)

• HW: Section review 2.2

MATTER UnitFriday, October 7

• Objective: SWBAT explain how density of a liquid relates to its viscosity. • BR:
