Inside a plug

 Gone are the days when students learnt to wire a plug, but it is still helpful to look inside and look at a home wiring diagram to see that the sockets and lights are all in parallel.

World Population Growth

World Population Growth in Two Graphs. Over my lifetime is nearly a straight line and none of the students were bothered until we looked at the population size over the past 7000 years

 

Computer Storage

 Some computer history shows students the 5 1/4 Floppy disk, The 720K 31/2 floppy Disk, and the 1.44K 3 1/2 floppy disk onto the Single density CD to the DVD and Hard Disk. I also have a 1980s 300Mb Winchester exchangeable platter, giving the students something to consider.

Online Teaching Success

 Online lessons work well for some subjects like maths - but how about science? After 7 years of online teaching, we know online teaching works well with science, but it also depends upon the students' setup, and if they can manage some half-decent, online works really well.

Ore Extraction

Ore extraction is done by adding some crushed calcium carbonate to a wooden spill and dipping it in copper or iron oxide. Heat fiercely, and with some practice, tiny balls of metal are formed.

 

Heating and Cooling

Doing some revision of Heating and Cooling. Set up two @pascoscientific wireless thermometers connected to Capstone, and whilst the student revised the software, did the rest, producing a graph of the results.

 

Factorising

 GCSE Maths - working on factorising - taking one term out and fully factorising taking more than one term out. Plenty of practice using the Wacom pen and screens.
