Variables in Science

Ok. You will be asked to draw a graph in IGCSE chemistry, physics, biology or science exams. In particular, you will be asked to draw a graph when you change one variable and measure what happens to the other variable. But let’s back up a bit. I’ve gone and used a fancy science word – variables. We need to sort out this concept before we rush into drawing graphs.

Resources for Home Education

Before I say anything about these particular needs I first of all want to make clear that we are very aware that many children that are home educated choose alternative routes that do not involve this sort of certification. This, of course, is a valid and worthwhile route – the main advantage being that the thirst for knowledge and the urge to explore are not bounded by the strictures of a limited set of objectives that lead to a narrowly focused exam...

Teaching Maths at Home

“I hear and I forget. I see and I remember. I do and I understand.” Well that’s what Confucius wrote and who am I to disagree. I have started with this quote and I will come back to it later when I get on to talking about teaching maths at home. But first – who is this article for? In writing this I am thinking about those who home school for one reason or another and also for those who want to support a child in their learning. It is also for other subjects too such as physics and chemistry where there is a large problem solving element.
