Hydrate Labs, Microscale Chemistry and Cage Fighting....

Bottle cap set up for hydrates

For years my students would heat the hydrates in glassware, burn themselves, break the glassware and splatter salts and thus their data, all over the lab bench. A few years ago Bob Worley came up with a great microscale technique. Essentially, it takes a used bottle cap without the plastic and this is used as the dish. Next, there is about a three inch machine screw that goes through a drilled hole in the cap. A nut is placed on the screw to hold everything in place and cheap pliers are used to hold the entire assembly over the flame.

Extension Activity with Isotopes Matter

Isotopes Matter Interactive Periodic Table

After receiving positive feedback from Peter Mahaffy, the IUPAC project co-chair of Isotopes Matter, I decided to add an additional component to the original isotope assignment I posted. The second component of the assignment focuses on the applications of both radioactive and stable isotopes using the interactive IUPAC periodic table.

Time required: 

55-60 minutes for both parts of the extension activity

Using IUPAC's Isotopes Matter as a Digital Learning Tool

Isotopes Matter

Isotopes Matter is a digital learning tool, developed by IUPAC Isotopic Periodic Table, designed to explain isotopes as well as their importance. This resource incorporates mass spectroscopy data into each of the key ideas as well as provides multiple examples as to how varying isotopes are commonly used.

Time required: 

Using Isotopes Matter and the class discussion: 55-60 minutes

Tackling Big Ideas

BIG IDEAS

It was the empty terrible feeling in the pit of my stomach at 9:30 at night that really bothered me as I am wading through the stack of papers that I was grading. I had the students do experiments, worksheets, I lectured and there was homework. Some of the students could “do” what I thought was science. They could calculate the answer. They could balance the equation.

“The Candle Experiment” – an Opening Exercise for General (or introductory) chemistry

candle flame

This exercise is intended as an ice-breaker for a first or second class meeting. It also serves as an introduction to physical & chemical properties and application of the macro/micro/symbolic representations of chemical phenomena. Finally, it also provides a framework to mention many of the topics to be covered in a general chem first semester course.

First Day of Chemistry: The Banning of Caffeine and Making Gummy Worms

The first day of school for me has always been daunting for my new students (in AP chemistry, where I know the kids, it’s so much easier). I want my students to know the following: -Who is this tiny person who looks like a teenager (that’d be ME, folks)? Where did she come from and why is she teaching us? -What does chemistry look like?
