Brushing Up on Chemistry

In this Activity, students make their own toothpaste and use various tests to compare its properties with those of commercial toothpaste. This includes testing its ability to remove stains from the dyed shells of hard-boiled eggs. The Activity allows students to discover more about a cleaning product they use every day.

Lab Accidents

The is an independent federal agency in Washington DC. They investigate industrial accidents. They just released a video of a young woman speaking about a high school chemistry class accident she was a victim of.

Ice clouds

I get excited when I see the outside temperature drop below 0°F (-18°C). This is not because I enjoy cold weather. It is because when the outside temperature gets this cold, I can conduct a particular experiment that I think is quite beautiful. Check out the video.

Using Orbital Viewer

Orbital Viewer is a fantastic program for displaying electronic orbitals. It is a great resource for teaching students about orbital shapes and the rules, nomenclature and notation of the quantum numbers n, l and m. 

Expo Neon Markers

As the trimester comes to an end, I have the chance to reflect with my chemistry students and ask them about course likes and dislikes.  A major "like" that came out was the use of the Expo brand neon markers.  I had heard about their use from Brian Bennett @bennettscience and how well they show up on the black lab tables.
