Someone in the know started teaching middle school chemistry about an year ago. A few months into the job, she needed help with her unit on exothermic and endothermic reactions. She specifically needed a classroom assignment to gauge her students’ understanding of the unit. The following is what I came up with to help her meet her goal.
This file lay dormant in my folder since then. I thought it would make a good post on day ‘E’ of the A to Z blog challenge.
Chemists, chemistry educators and you fine people – what do you think of the assignment?

Here are the two videos that set the tone for our discussion on Explosives.
The first, from one of the movies I love, The Hurt Locker.
And this, a brief discussion on the Boston bombings. Specifically on IEDs. Pressure cooker bombs, in this case.

Appended below is the PowerPoint file I used in class today. We will be continuing with the same file on 22 December, 2016.
Topics covered here:
How do fingerprints form?
Types of fingerprints
Detection and Visualisation of Latent Fingerprints
Chemical Methods of Development of Latent Fingerprints:
- Iodine fumigation
- Silver nitrate method
- Ninhydrin method
- Cyanoacrylate (superglue) fuming
