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?

Inquiry, "Sticky Water" and some great models...

Sticky Water Lab

 I just completed covering "ionic and covalent" bonding with my studenets. I wanted to bridge the gap to intermolecular forces. I found a great lab called "Sticky Water" from Target Inquiry - Grand Valley State.(link is external)  Before I continue, I have to provide "full disclosure". I spent three years with the Target Inquiry Program at Miami University Ohio (Project TIMU(link is external)). There is a lab called "Sticky Water" that was written  by a teacher in the Grand Valley State program. First, the activity focuses on just water, then ethane, then ethanol.

Topics featured in this issue include: examining the flipped classroom; central ideas in chemistry & teaching; chemistry, art, & color; expanding student understanding; improving student communication skills; analytical chemistry & instrumental analysis; experimenting with natural products; undergraduate research experiences; educational resources; from the archive: using nonfiction to teach.

How Running a STEM Club Benefits My Classroom

ACS Chem Club

I run an after school STEM club that involves many projects and activities. Students build robots for FIRST Robotics, race RC cars, use 3D printers, and build underwater vehicles. They dissect specimens, and create biodiesel from vegetable oil. So why would I bring this up on the Chemed Xchange? Our science club does chemistry activities, we are an ACS Chem Clubs(link is external), but I think there are many other benefits to this kind of club. Here are a few:

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.
