Warm Up • Take 10 sheets of graph paper and 1 sheet of blue paper • Staple the blue sheet of paper on top of the graph paper to make a booklet • On the center cover of the blue paper write the following in blue/black pen: – – CHEMISTRY GT LAB NOTEBOOK Your Name Period 1 Ms. Ose • Take out your 12 -4 practice problems and begin to complete numbers 3, 5, 7, 9

Objectives • Today I will be able to: – Calculate the quantity of transferred in an endothermic and exothermic reaction – Set up my lab notebook for the calorimetry lab

Homework • Finish setting up lab notebook • Wear closed toe shoes for lab tomorrow

Agenda • • Warm Up Calorimetry Practice Problems Calorimetry Pre-Lab Exit Ticket

Calorimetry Practice problems Complete practice problems 3, 5, 7, 9 at your desk. You have 20 minutes. We will review the answers as a class.

Calorimetry Pre-Lab

This quarter you will maintain a lab notebook

Lab Notebook Requirements • Must be written in pen • All pages must be numbered • Errors are not scribbled out but have one line drawn through and are initialed • All data is directly written into the notebook (not on a separate sheet of paper first) • It is okay to make mistakes

Today, we will set up the lab notebook together for the first time

Take the next 5 minutes to read through the lab and procedure A and B. Then set up the title, date, name, diagram and purpose for the lab.

As a class you will create the data tables on the board first and then transfer them into your lab notebook (15 minutes) – One student will draw the table as other students share ideas

Lab Safety Preview • Goggles, closed toe shoes and aprons must be worn during the lab • Hot water bath is hot. Do not touch without safety gloves • Use tongs to move the metal washer from the hot water bath to the calorimeter • All solutions can be disposed of down the sink with water

Closure • Write a summary of the lab procedure you will use in lab tomorrow.
