Tracker revisited

The free, open-source Tracker software package, written by Doug Brown of Cabrillo College, has been a favourite of ours at SSERC for over a decade. Tracker is many-faceted, but at its core is the ability to analyse video and still images. Students working at home could perform meaningful practical work using the application.

Studying animal cells at BGE using liver cells

In this time of COVID-19, SSERC has received several enquiries from teachers and school technicians about the safety and desirability of carrying out cheek cell sampling for microscope work. While this is a safe activity,, it does require that learners to adhere strictly to the guidance.  As an alternative, here we set out a protocol using fresh liver as a readily available and cheap source of animal cells suitable for microscopic examination by learners.

Determining the iodine value without Wijs

For some years now there has been an activity on the SSERC website about the synthesis and testing of biodiesel. The test for unsaturation traditionally uses Wijs solution (alkaline iodine monochloride). This is expensive to buy and hazardous to make: here we offer a simple, quicker, safer method.
