You will have 2 periods today to compete your design and record your voltage.
_____________
LAB Activity 2 – design a voltaic cell with greatest voltage– modest breakfast up for grabs
This Lab write-up is a group slide-up. There is only one presentation per lab group and the entire group will get the same grade. I have emailed everyone with their group a link to the shared presentation
You need to present on the slides in the Presentation the following:
1. Title page with all Lab partners listed.
2. Objectives.
3. Materials Page listed with all available components
4. Labeled Diagram Slide of proposed voltaic cell design – Draw a diagram with your phone

9/14 – Wednesday – B Day – 3b Lab, 4 single
Main focus –
a) To connect Faraday’s early work with our new stoichiometric calculation that determines the amount of metal plated at the cathode.
b) To discuss the use of units in dimensional analysis.
1. Discussed Faraday’s work and what was discovered in his electrolysis experiments
2. Reviewed Page 1 of the homework and continued to the second page as classwork. Period 4 class I also reviewed the Monday’s homework setup.
