AI computer Programming


 A-level Computing projects - who writes the best programs ChatGPT or a student and can I tell which is which? Looking at the comments and asking ChatGPT seems to work.

Measuring Exothermic reactions

Trying 0.1g then 0.2g and then 0.3g Magnesium with 1M Copper Sulfate and comparing the temperature rise and the rate of that rise. The orange line was different since we used @pascoscientific Sparkvue rather than Capstone to capture the data.

Using the ripple Tank


 Are circular waves different from straight waves? Taking time to find out. The wave's amplitude decreases as the circular waves radiate out, but their wavelength and frequency stay the same. Need to try this in the pool (a much bigger ripple tank) to find out more.

Solving Graphically


 The students had a go at solving some simultaneous equations graphically. All of them drew the axis of the graphs on the graph paper before working out the table of values and working out the scale. The result they had terrible problems working out the solutions.

Virgin Media down


 Virgin Media down all day today. Very difficult to do much work without it. Fortunately, no students online. We had to use the backup 50Mb BT system for everything instead of the 1Gb line

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.
