I made a clunky cartoon about cracking alkanes with a cheery soundtrack. The idea is for students to write and record the narration… something different to just ‘writing up’ the experiment.

Molnupiravir: exam practice.

Exam boards often take unknown substances and ask students to apply their understanding of chemistry to them. To provide practice answering this type of question, I am developing a series of worksheets with this type of question. The series is called Practicexamquest. Molnupiravir has recently been approved as an anti COVID drug, so is of topical interest. Comprises 7 questions over 2 sides.

Students work out the state different substances are in at room temperature, given their melting point and boiling point.

One of my wacky videos illustrating the difference in reactivity of benzene vs phenol in terms of polarising power.

This maybe helpful as a small revision exercise. Has a ‘check my answers’, ‘solve’, and ‘hint’ button. This runs in your browser. Simply click on the file called ‘index’ Please note: in order to provide a rich interactive experience, my interactive resources are mini-web sites local to your computer. After unzipping, they comprise a folder containing the main .html file and another folder containing the graphic resources and my coding to make the resource work. Double click on the .html file and the resource will work. If, however , you move or delete any of the files from this hierarchy, the resource will not work.

I have made a cartoon of dot cross type diagrams for all of the structures on the AQA specification. Simple double click on the covalent bonding.html file and it runs in your browser. Its nice and colourful, big and bold (zoom in with your browser to make it as big as possible). Could use around the whiteboard, or for independent study at a computer. It’s not intended as a whole lesson, but as a useful resource that can be revisited a number of times with a class to reinforce what they need to know for the exam. Could be starter or plenary or interlude. Please note: in order to provide a rich interactive experience, my drag & drop resources are mini-web sites local to your computer. After unzipping, they comprise a folder containing the main .html file and another folder containing the graphic resources and my coding to make the resource work. Double click on the .html file and the resource will work. If, however , you move or delete any of the files from this hierarchy, the resource will not work.

I made a crazy cartoon illustrating the calculation of the enthalpy change from bond enthalpies for the reaction between chlorine and hydrogen. Just for fun really. Note: the youtube version is free.
