1. Gas Law Showdown You need a calculator & PT
Notebooks with task 3 questions
Turn in ideal gas law sage n scribe if completed
(if not you will have time at end of class- maybe)

2. Task 3 Questions
You should have at least 1 question if not 2 in your notebook.
If you do not have a question written please go sit at a lab table and write your questions.
Find someone who you are not sitting with and…
Switch notebooks.
Give feedback on their question: is it open ended, testable, and define the variables
Once both done discuss how they could make their question better

3. Details of the project:
Making Scientific Teams: You may pair up with another student to complete this project. Teams do not have to be in the same period, but will have to present individual to their class on peer evaluation day. Pairs must be approved before start of the project. You may not team up midway through the project. It will be up to you and your partner to split the work evenly. Scientific teams will receive the same grade on the project and may not argue grade differentiation. Choose your team wisely.
