Date: 11/30/2012 and 12/3/2012
Class: Physical Science
Periods: B2,3 and W1,3,4
Outcomes: Students will be able to identify when a double-displacement reaction has taken place.
Standards:
Student Needs:
Assessment Plan: Lab report
Lesson Outline: Have students figure out the chemical formula for a compound of potassium nitrate (KNO3) > have students balance an equation of BaCl2 + Na2SO4 -> BaSO4 + 2 NaCl > explain directions for lab > students do lab > ask students to explain what happened > fill in holes > go through lab report
Review: Have students figure out the chemical formula for a compound of potassium nitrate (KNO3) > have students balance an equation of BaCl2 + Na2SO4 -> BaSO4 + 2 NaCl
Anticipatory Set/Opening: Lab Day!!!! > ask students to identify what a precipitate is and how it’s made
Key Points: double-displacement reaction result in the formation of a precipitate (a solid forming from the mixture of two liquids) due to the insolubility of one of the products
Teaching Input: asking questions, giving directions
Modeling: explaining lab
Checking for Understanding: have students repeat directions
Guided Practice/Monitoring: Lab
Closure: Emphasize precipitates form when one compound is insoluble in water
Independent Practice: Read 21.4 pgs. 646 to 650
