Relate to Students' Experiences |
Relate equilibrium to students’ own experience of strong versus weak acids. For example, you can put vinegar on your fish and chips but not HCl. From high school they might have an understanding that vinegar is a weak acid compared to hydrochloric acid, but they never knew why. And you could... more |

Use Both PowerPoint and Visualiser |
Use two screens in a lecture and then turn one off and go to the visualiser and spend time on the visualiser drawing things or solving problems or writing something. And at that point the class becomes engaged. So when you’re using PowerPoint, unless you’re really good with it, they’ll disengage... more |

Work Out Charges |
Ask the students to look at structures and consider what charge different parts of the molecules will have when they are protonated and deprotonated (eg. COOH to COO- is neutral to negative, and NH3+ to NH2 is positive to neutral, but can have OH... more |

Relate to Drug Behaviour |
Use drugs as an example of the relationship between how much of a species is protonated and how much is non-protonated. This is an equilibrium process. For a carboxylic acid drug, if it’s protonated it’s not ionic, if it’s not protonated it’s anionic. And if it’s going from gut into blood for... more |

Copper in Silver Nitrate Demonstration |
If you put copper metal in a silver nitrate solution, the solution becomes blue and you get silver metal. Ag+ is becoming Ag and Cu is becoming Cu++. The students see both oxidation and reduction happening - and happening at the same time. If you do it close to Christmas... more |
