Date: 11/19/13 and 11/20/13
Class: Physical Science
Periods: W1,2,4 and B2
Outcomes: Students will be able to graph and predict the boiling point increase of water with addition of sodium chloride
Standards: UCP.1-3,5; A.1,2 B.2
Student Needs:
Assessment Plan: Lab Report With Graph
Lesson Outline: What are the 4 parts of an experiment? How many protons does Aluminum have? What are the 4 types of rxns? > Why do they salt roads when they think they’ll be icy but not when it’s just snow? > Give directions for lab: start with 1g of salt and 30mL of water, measure the temperature the water boils at, repeat for 2g and 3g. Have them put their data on the board then have them graph the averages of their data. Predict the boiling point at 4g and 5g of salt. > Talk about adding salt to water to boil water > 22.3 Section ?s > Read 22.4 How does soap work?
