Gas It Up This Week!

After completing their unit test on Friday, the chem 20s will be introduced to Unit B Gases this week! This unit, many students find extremely easy, and logical. The gas laws are very mathematical and they just make sense. That being said, it is the shortest of the units, and doesn't lend itself to anything in chem 30 (unfortunately). Being a logical unit, I teach it more as an inquiry based unit, in which the students perform small labs and make sense about what is happening to the gases during the experiments! It's a fun way of teaching and makes it a lot more hands on. 

Just a reminder, parent teacher interviews are coming this week, and please book one if you have concerns or questions about the class. Please do not come in "guns-a-blazing" about the lab marks. If your child's mark was low, it is merely because they wrote their lab at a level lower than expected for chem 20. I am running a tutorial entitled "HOW TO WRITE A LAB REPORT FOR THE MEANEST TEACHER AT CHS" on Wednesday during FLT time, and I invited all the students to come and learn more about what is expected of them to be successful in chemistry 20. The low lab mark is a replaceable mark, however it will have to wait until the end of the semester. Students are able to perform a replacement lab to replace their lowest lab mark during the FLT classes prior to exam break in June. That being said, by June, this lab will be worth virtually nothing (0.5-1%) of their overall mark, so they may choose NOT to perform the replacement lab. Lab reports are a learning experience, and after a while, the chem 20s will be pros at writing proper chemistry lab reports.
