Checking Progress

We are using the die to keep track of where everyone is in the lab. Make sure to update it as you change sections.

When done with the lab, your die will have the 6 pointing up as shown here.


Start the Lab

Keep your dice turned to the section of the lab you are on. (Instructionsare provided in the lab handout)

Please refer to the Lab Handout and let’s get started!
