Teacher as Researcher

Fri, 05/08/2015 - 09:55 -- Shelly Belleau
Teacher Researcher

n teaching we regularly change our class structures and routines and we implement new “interventions” in hopes of changing classroom dynamics or reaching more students.  I know that most of the time I make these decisions based upon anecdotal evidence, perhaps after glancing at a handful of exit tickets from my students or based upon how I “felt” the class went.  Recently, though, I’m finding myself a little more hesitant when making a claim about my class.  I require that my students support their claims with evidence, so why wouldn’t I also support mine with evidence?

CHEMISTRY OUTREACH

I have been involved in several types of community outreach projects to promote science education and chemistry. One of the best was a biannual event I worked on with teachers from each elementary school in our district and from our middle school. It was a Science Extravaganza.

What are they thinking? Where did they get that idea?

Making Thinking Visible

Have you read “Making Thinking Visible”?  You should. It focuses on making student thinking visible to the teacher. While still learning to use the visible thinking routines, I really feel more conscious of students’ understandings than ever.  

Here is a sample activity that I adapted to fit my honor chemistry students’ needs:

How Does an Orange Peel Pop a Balloon? Chemistry, of Course!

Tue, 03/24/2015 - 15:15 -- Tom Kuntzleman

The juice from an orange peel causes a balloon to pop.  When I first saw this effect I immediately thought to myself, “what is the chemistry involved in this experiment?” After quickly searching the web, I found several claims that a compound in orange peels called limonene (Figure 1) is responsible for this effect.  Limonene is a hydrocarbon, which means that molecules of limonene are composed of only carbon and hydrogen atoms.  Limonene is responsible for the wonderful smell of oranges, and it is a liquid at room temperature.

Why do we have to do chemical equations and calculations?

Fe & Sulfur reaction

(A look at workplace exposure limits found in MSDS sheets)

There is useful information in section 8 of a (Material) Safety Data Sheet (MSDS) that teachers can use and shows how a knowledge of chemical equations and calculations helps protect the health of their students and themselves and helps to assure their employers and safety officers that teachers and lecturers are responsible and professional users of chemicals.

Opportunities For Chemistry Modeling Training

Tue, 02/24/2015 - 18:02 -- Deanna Cullen
modeling training

The Modeling™ curriculum emphasizes modeling, collecting evidence, scientific discourse and development of conceptual understanding. All of these can be linked to AP and NGSS standards. If you are looking to make improvements in your curriculum and gain some impressive strategies, consider enrolling in a workshop this summer. There are many workshops scheduled around the country during the summer. A full curriculum and support materials are provided.

Chemical Mystery #4: The Case of the Misbehaving Balloon

Tue, 02/03/2015 - 11:19 -- Tom Kuntzleman

Conducting experiments with liquid nitrogen experiments is a sure-fire way to energize many chemistry lessons. Unfortunately, getting access to liquid nitrogen can be a bit difficult. I happen to purchase liquid nitrogen from Airgas; you might be able to find a branch near you here.
