volumeIII. Density stations!IV. Exit TicketHomework: Week 3 Homework #1-5Lab report due tomorrow!

Stations

With your lab group, visit each station (9 min. each)

Work quickly to determine what measurements you need to make, and record them (with units!) in your notebook.

Then, calculate the quantity specified on the poster. Include units!

In Your Notebook:

Station 1:

Expectations

Stay with your group and move on only when the timer gongs.

Begin working immediately. Use a reasonable, quiet professional

voice. Return all items to the station in an

organized way. Show all your work neatly!

Discuss
