Blending a Periodicity Unit

Previously I wrote about taking part in a district-wide high school blended learning pilot. You can read about it here. I received my Chromebook cart near the end of February/beginning of March. A little late but just in time for the periodicity unit I was planning as a blended unit. The following is a breakdown of how I designed the unit.

Give Me Back My Copper! A Simple, but Multi-Faceted Lab Activity to Review Lab Skills in Week One of AP Chemistry

copper lab

In the lab, students are given a 1.5 gram samples of copper. The copper is taken through a series of five chemical reactions ending with the precipitation of solid copper. After the five reactions, students are asked to return their 1.5 gram samples of copper to the teacher.

Target labs, Reviews and THAT kid...

It is really hard to get to know THAT kid especially when I have classes of other kids who are important and have needs also. Stack on top of this teenage hormones, spring, nice weather, prom, AP tests, state testing and trying to sell as hard as I can how fun "stoichiometry" is....I now run the risk of turning a bunch of other kids into THAT kid pretty quickly.

Chemists Celebrate Earth Day

The April 2016 issue of the Journal of Chemical Education is now available online to subscribers. In honor of Earth Day 2016, the April issue includes a variety of content that provides ideas and suggestions for bringing environmental chemistry to students on the topics of: water quality; climate science and greenhouse gases; atmospheric chemistry; sustainability, green chemistry, and environmental awareness; and energy storage technology. Also in the issue are articles on: outreach and public understanding; teaching organic chemistry; physical chemistry; exploring biochemistry with proteins; research experiences in the laboratory; educational resources.

Capturing the Beauty of Chemistry with an iPad

In my IB Chemistry class, my seniors were finishing up independent investigations for their Internal Assessment a few weeks ago when something cool happened. One of my students was using silver nitrate and potassium chromate for a titration. This is notable to the story here because the endpoint is marked by the formation of silver chromate as a precipitate, with a deep reddish color. I overhead the student showing his reaction to another student, with both of them commenting on the cool colors involved.

Colligative Properties in Real Life

This year in the midwest United States, winter has been a fickle friend. I haven’t seen the same amount of snow or ice as in recent years, but I still made sure I was prepared for it at our home. I went to my local big box hardware store in December and contemplated buying rock salt (NaCl), and NaCl/calcium chloride mixture, or just calcium chloride. Growing up my dad had switched entirely to calcium chloride because it was less damaging to the brick pavers leading to our porch and backyard. In fact, calcium chloride is generally much safer toward plants and soil than NaCl. Even though calcium chloride is much more expensive than rock salt (it was about twice the cost for 10 pounds more), that what’s I chose. Why?
