Atomic Shapes

 A-Level Chemistry Tuition: Looking at the shapes of the Atomic orbitals to try and make some sense of the features we see in the periodic table - the evidence for s and p orbitals and how the shapes fit inside each other - where this model falls down.

Creating a calibration Curve

A-level Biology Tuition: My students create a series of serial dilutions of Glucose to work out the concentration of an unknown. They use the @pascoscientific colourimeter to create a calibration curve and Benedict's solution to make a quantitative assay.
 

GCSE Higher Maths

 GCSE Math Tutoring: I work with GCSE Students to increase their chances of getting higher grades. Each week, they come to me not being able to do something, and they go away being able to do this. Soon, they run out of things they can't do.

Force and Distance

 GCSE Physics Tuition: Students investigate how the force changes with the distance from the fulcrum as we investigate moments, gears, pullies, and levers.

Spiders

GCSE Biology Tuition. It's spider season with lots of cobwebs and many Orb Web spiders like this one, but it's not the only type, and there are many different ways to get their food. We stop to look at their various ways to fill the ecosystem.

Building a Computer

 GCSE Computing Tutoring: Probably the best way to understand a computer's components is to build one from scratch. The students are given a case, motherboard, CPU, RAM, hard disk, power supply, graphics card, and monitor, and then an OS is installed, and it works.

Ionic Bonding

 GCSE Chemistry Tuition: Using the cardboard models to gain a better insight into the donation and receiving of electrons creates bonds. Atoms like Magnesium have two sticky-out bits representing the two electrons that can be donated, and negative ions have in bits to accept these donated electrons to give complete shells.
