Gases, the New Year and Getting Brains into Gear....

ChemFax

This year our school, through a unique set of circumstances, had final exams before winter break, two weeks of break and then one week left in the semester after break before second semester officially ends. It is a weird situation. We were in the middle of gas laws and now have to pick up where we left off after the kids have not been attending school for two weeks.

Relative Reactivities of Metals

Last winter I watched a webinar put on by ACS and AACT called "NGSS in the Chemistry Classroom." As a result of watching that webinar, I took an activity that had NGSS Science & Engineering Practices (SEP) integrated into it and tried it out in class. In this activity, students are required to develop their own procedures and data tables.

Blended Learning Pilot: #1

www.greeleyschools.org

Last year, I researched and practiced what I thought to be "flipping the classroom". But, now that I am taking part in a district-wide "High School Blended Learning Pilot", I can say that I was attempting blended learning early in my teaching career. You see, the flipped classroom is really a small subtype of blended learning. So, the goal of this post is to define blended learning and share what my professional development has in store for me during this academic year.

Concept Mapping as a Review Tool

It's that time of year for those of us on the semester block system - end of course content state exams loom large and student stress is at an all time high. The longer I teach in this environment, the more I see how these tests push teachers to provide packet after packet for review. The stakes are so high for everyone - and teachers are afraid they missed something.

A Quick and Dirty Stoichiometry Lab...Differentiation and Inquiry?

Quick Stoichiometry Lab

There is a traditional stoichiometry lab I have done before. It involves adding dilute hydrochloric acid to sodium bicarbonate, boiling off the fluid and then getting the mass of the sodium chloride. Students then can solve the percent yield for the sodium chloride based on the amount of sodium bicarbonate they use. It is not a bad lab.Something about having hot ceramic watch glasses with acid just makes me a bit nervous.I am not sure where I got this new lab, but it has been one that has evolved over the years It is quick, dirty, relatively simple and uses over the counter (mostly) materials.
