Laptop upgrade

 How to revitalise an old i7 laptop by adding a 1TB SSD and upgrading the RAM to 16Mb from 8Mb for £80. Reinstalling windows from scratch and a terrific boost in speed. This 10-year-old laptop was faster than many students' laptops after the upgrade. Teaching and demonstrating A-level Computer Science at Hemel Private Tuition, part of Philip M Russell Ltd.

Fun with Transformers

 Using transformers to set up, set down and isolate. The students liked the idea of isolated circuits with seemingly no generator or battery to power them, just a magnetic field at Hemel Private Tuition part of Philip M Russell Ltd.

Dissolving Lead Iodide in Hot water

 A fun reaction is to mix Potassium Iodide with Lead Nitrate. More fun =is to then heat the solution to drive the reaction backwards and then let the Golden Rain form. It takes a long time to do and so I often prepare another one ahead of time

GCSE to A-Level Maths

 Upgrading your Maths - going from GCSE to A-Level is quite a jump and this course makes it much easier. Students learn much harder GCSE problems and how to solve them, which makes the A-level start so much easier.

More Pendulums

 Learning all about Pendulums, how changing the swing or changing the mass has no effect on the swing but changing the length of the string does at hemel private tuition.

Physics from first Principles

 Students often get the idea that physics is made from the Rules rather than rules to begin created to fit the facts. Here using a @pascoscientific smart cart on a track with Capstone they can write the scientific equations from scratch.

Microscopes - high or low power

Which is best, high or low power microscopes. Both are great, but for students starting out and wanting a home microscope, I suggest that a low-power microscope is far better value and will be used more than the high microscope, which often needs specially prepared slides to view.
