12/6/12 and 12/7/12

Date: 12/6/2012 and 12/7/2012

Class: Physical Science

Periods: B2,3 and W1,3,4

Outcomes: Students will be able to describe how substances dissolve and what solubility is.

Standards: UCP.1-3,5; A.1,2; B.1-3,6; 

Student Needs: 

Assessment Plan: Ticket-to-leave= students will define in their own words what solubility is.

Lesson Outline: Balance C₃H₈ + O₂ -> CO₂ + H₂O > Draw a molecule of Se and Cl > Ask students what a solution is > Notes over 22.1 and 22.2 > Dissolving demonstations (temp and maybe size) > 

Review: Balance C₃H₈ + O₂ -> CO₂ + H₂O > Draw a molecule of Se and Cl

Anticipatory Set/Opening: Ask students what a solution is

Key Points: Solutions are homogeneous mixtures with uniform composition, solubility is how much of a substance can be dissolved in another substance (like water)

Teaching Input: Asking questions, giving notes

Modeling: Video on how dissolving occurs

Checking for Understanding: Have students look at the chart on pg. 673 and ask them which substance is the most soluble.

Guided Practice/Monitoring: Have students explain the demonstrations

Closure: Ticket-to-leave= students will define in their own words what solubility is. 

Independent Practice: Read 22.3 and 22.4 pgs 676 to 685 focus on how do solutes change a solutions properties and why don’t oil and water mix

Reflection:
