Kairos Students: Welcome back!
First, Read and take notes on page 401-406 in your textbook. Then, answer questions 1-6 on page 406.
Then, you're going to complete the first two pages of a worksheet on a phet simulation. Here's the link: http://phet.colorado.edu/en/simulation/soluble-salts
The worksheet that goes along with the sim can be found under Homework Docs. YOU ONLY NEED TO COMPLETE THE FIRST TWO PAGES. Start by just messing around with the sim so you can see how it works. Make sure to look at the information provided about the amount of salt and water on the right hand side. You will need to use the tabs at the top for the second page of the worksheet. Be sure the READ DIRECTIONS carefully throughout the worksheet!
NOTE: If you don't get the Pre-Lab Vocabulary definitions from the textbook first, you will have a lot of trouble completing the worksheet!
