WEEK AT A GLANCE: WEEK 4

 

VIDEO: CALCULATIONS REVIEW

In this VIDEO, Mr. Hatfield reviews the procedures, previously taught in the fall semester, for calculating molar masses with the aid of the periodic table.

Mr. Hatfield then shows how a substance's molar mass and other conversion factors (Avogadro's number, the molar volume) to show students how to interconvert units of mass, volume and number of particles.

Please note that these slides represent the 'direct instruction' part of the first three days of instruction in the spring semester, with new material (on solutions) set to appear on the fourth day of instruction.

MOLES TO GRAMS, GRAMS TO MOLES: PREVIOUS LAB CALCULATION VIDEO

 Students, last week you reviewed how to convert moles to grams (and vice versa). This was previously covered during the first two weeks of September in the Fall Semester, and as part of that we had a lab activity called 'Combustion of Paraffin'.

In this VIDEO, I showed students how to the calculations required in that lab, which involved molar masses and grams/moles conversions, and this may help you review the concept:

WELCOME BACK!

Students:  Welcome back from Winter Break!   

I hope you had an opportunity to "recharge your batteries", and reconnect with family and friends. 

Now, coming back to school, we have another opportunity: to reflect on the challenges we've faced in the last several months, not just as students, but as people.  I know it hasn't been easy.

But, as the saying goes, the future is where we are going to spend the rest of our lives, and we need to look at the future in this new year.  With that in mind, there will be important changes at Bullard High School in the spring semester.  The most obvious change, of course, is the new schedule:

The longer (75-minutes) periods on Tuesday through Friday will require us to "up our game" in terms of attending and participating in class.  To help give more structure and routine, I will be adopting the following scheme, which I call a lesson frame.   This entire document has been made available to all students in your class's Teams channel:

Remember: students should check this class blog regularly for resources, especially videos that summarize lectures or provide demonstrations on how to solve calculations.
