“Ingredients” Lesson Plan

People have been asking me for the lesson plan that gave rise to the Banana Posters.

Here it is. Click the image to download it as a PDF. 🙂

It’s a great introduction to Organic Chemistry in the last year of high school or in the first year of university.

3D Periodic Table with a G-Block (beta)

Here’s something you should all have in your Chemistry classrooms.

This project was a mashup of two existing ones.

In 1969, Roy Alexander in the United States invented a helical periodic table with pop-out loops for the d-block and the f-block. It was by far the best way to visualise the periodic table at the time. His brilliant 1969 design patent is online here.

Then in 2010, Pekka Pyykkö in Finland created a periodic table that can accommodate elements up to Z=172, far beyond the range of elements that scientists can currently synthesise (currently Z=118 at best estimates). Pyykkö calculated the bizarre electron configurations of the g-block, and added these yet-to-be-discovered elements underneath the existing periodic table.

I blended these two ideas together and created a 3-dimensional periodic table with a g-block: Pyykkö’s elements in Alexander’s shape. The whole thing is about 30 cm high. I coloured all the elements by their electronegativities (where known).

Geography has globes, Biology has those limbless mannequins with their organs showing, and now Chemistry has this. It’s by far the most superior way to visualise the periodic table and electron configurations in 3D. It’s the only periodic table that puts all the elements in the right order without any gaps. It’s future-proof, fool-proof and waterproof.

Email me if you want to get your hands on one. Enjoy 🙂
