In his final issue as editor, Geoff Auty is pleased to present five practical science notes.

Peter Borrows explains the lateral flow test that we all became familiar with during the Covid-19 pandemic. Iain MacInnes explains why objects rolling down a slope do not move at the same speed as those sliding without friction. In a second article, he describes a way to obtain a spectrum from sunlight, using water and a mirror. Rik Clay illustrates a method for finding the temperature of the flame from a Bunsen burner. Randal Henly shows some methods to demonstrate resonance and interference with sound. 

The longer articles start with Jon Hale exploring how using immobilised yeast can help students to develop a more synoptic understanding of the practical skills as well as the concepts. Michael Reiss and Mark Winterbottom explain that education in biology is not best served by only learning what is in the textbook. Michael Reiss and Tamjid Mujtaba explain the BRaSSS approach, an abbreviation for Broadening Secondary School Science.  Martin Pickett and Berry Billingsley examine the relationships between science and modern foreign languages using the development of autonomous cars as an example.

The ASE send their profuse thanks to Geoff for his significant work on SSR over the decades and wish him all the best.
