Measuring the magnetic field

Some students used a @Pascoscientific Smart cart, others used a rotary motion sensor  turned to linear to work out distance against magnetic field strength moving through a permanent magnet and a solenoid using AC or DC

ECG sensors


 Connecting students to the @pascoscientific EKG sensors (ECG) and recording their heart rates before and after exercise. The students can clearly see the structure of the electrical signal and can label their own, which is more fun and rewarding than just learning from a diagram.

Computing Projects

A-level computing Projects are on their way. Some using LAMP - Linux Apache, a database - often MariaDB and Perl/Php or Python as a basis for the development running on a Raspberry Pi. Many have some AI in the proposals, as this seems a great introduction.

Peacock Ore


 Behold #PeacockOre – a dazzling delight of nature. The colours dance & shift as you move it around. It's a beautiful blend of copper & iron sulfides, chemically Cu5FeS4. Easily one of the most enchanting ores out there. #Minerals #Geology

Rates of Reactions


Lots of use of the @Pascoscientific kit this week, today measuring the rates of reactions at different temperatures, plotting the rates, and trying to work out the relationship. After a go on the board the students discovered that Capstone could do this automatically.

Modelling Mechanics


 Using the inclined plane and a Newton meter to examine the forces involved. Changing the runway surface to change the friction coefficient to investigate how the forces change. Altering the angle to change the sin and cos values. Lots of calculator work.

Perpendicular Gradient Rule


I was going through some AS Maths Questions with some students and I was surprised that none of them had met the Perpendicular Gradient Rule

Gradient of Line 1 x Gradient of Line 2 = -1 if perpendicular
