Break between lab days for Parts 1 and 2 of Wood Lab.
Answered questions on Part 1.
Went over what happened in each step of the lab in preparation for drawing the flow chart.
Showed how to draw the bar graphs for testing conservation of mass.
Showed what each category of the data table meant. Drew pictures to better illustrate what was expected for each entry.
Showed how to fill in the data table for the Volume of Gas and how to do the calculation.
Sketched the flow chart on the board and showed how to label the arrows and where to indicate which steps were physical changes and which were chemical changes.
Drew a picture showing how the set-up looks like a person smoking and how, if you smoke, all the foul stuff from the lab condenses in your lungs. Told the students this was the idea I was looking for in the Conclusion relating to real life section.
Went on and prepped Part 2 of the Lab.
Described what is meant by distillation and how it is used in this lab.
Sketched labeled diagram of the lab setup and showed an actual setup.
Wrote procedure on the board with emphasis on tricky points and safety concerns.
Asked students to continue writing up any sections of Part 1 they did not complete and to prepare Part 2 diagram, procedure, material list, and safety precautions for tomorrow.
Handed back homework from section 2.3 of the textbook. Many students did not turn it in.

Put on board how to collect data for gas, and how to calculate the volume of the gas.
Also showed how to make the graphs comparing the masses of the reactants and the products.
Students did a second run and some did a third run.
For HW asked students to type up more of Part 1 of the lab.
On Monday we will discuss Part 1 and then show the setup and procedure for Part 2.
