Date: 9/6/2012
Class: Physical Science
Periods: B2,3 and W1,3,4
Outcomes: Changes in physical changes do not change the chemical identity of a substance. Physical and Chemical properties can be used to separate materials.
Standards: UCP:1-3,5; A.1,2; B.2
Student Needs:
Assessment Plan: Ticket to leave: have students describe the process of distillation and what kind of property (chemical or physical) it uses.
Lesson Outline: Review > Quiz > Lecture > Book ?s 1-4 > Boiling Pop/Salt Water Demo> Ticket to leave closure
Review: Review parts of an experiment and difference between heterogeneous and homogeneous mixtures.
Anticipatory Set/Opening: Billions of people rely on separating salt from seawater for fresh water sources.
Key Points: Physical properties affect behavior but not the chemical identity of a substance. Chemical properties affect how substance chemically react. Both are used in separating substances.
Teaching Input: Directions for quiz. Lecture. Going over quiz.
Modeling: Showing how to get to quiz. Boiling Pop or Salt Water. Showing form for ticket to leave.
Checking for Understanding: Ask students to repeat directions. Quiz to check understanding of reading assignment. Use ticket to leave to see if students can identify a physical change.
Guided Practice/Monitoring: Quiz, pairs talking about book questions.
Closure: Ticket to leave: describe the process of distillation and identify it as either a physical or chemical change.
Independent Practice: Does cooking involve a physical or chemical change?
