We Lied To You

This book contains 50 lies taught in the VCE Chemistry course.

These lies include well-meaning simplifications of the truth, mistakes in the textbook, and, in a few extreme cases, blatant falsehoods.

This book isn’t a criticism of the VCE Chemistry course at all. In fact, I just want to highlight the sheer complexity of Chemistry and the need to make sweeping generalisations at every level so it can be comprehensible to our students. This is a legitimate practice called constructivism in pedagogical circles. (Look that up.)

Many of these ‘lies’ taught at VCE level will be debunked by your first-year chemistry lecturers at university.

Here’s a preview of some of the lies mentioned in the book. Check out all 50 by clicking the download link at the bottom of the page.

Foldable Biomolecules

Visualising reaction mechanisms in VCE Chemistry can sometimes be difficult. Making plastic models helps, but I’ve been thinking that it would be much more convenient if students had their own paper version of molecular models that they could keep for themselves and use at home.

That’s why I created Foldable Biomolecules. Each Foldable Biomolecule is a PDF template that students can fold into a shape that demonstrates a chemical reaction clearly. Pull apart the edges of each sheet to visualise a hydrolysis reaction, and push them back together to visualise a condensation reaction.

These paper-based biomolecules are downloadable, shareable and much quicker to set up than their plastic counterparts.
