2/13/15 Percent Yield Lab

Date: 2/13/15

Class: Chemistry

Periods: B1

Outcomes: Students will use a lab to show the difference between theoretical yield and actual yield.

Standards: 9-12.P.1.6A

Student Needs: 

Assessment Plan: Lab Report with yield practice.

Lesson Outline: Bellringer > Practice a stoichiometry problem > Explain that theoretically what stoichiometry tells us we should get isn't always how it works out in real life. > Give directions for lab > Demonstrate how to do lab. > After lab ask for their starting and ending masses > Go over how to find theoretical and actual yields and then the percent difference. > Read 12.1 pgs 402-410 How does the kinetic-molecular theory explain how diffusion works?
