Getting to the root of the matter

 Learning skills in science is as important as learning facts. We have been practicing fixing root cells to look at mitosis. What the students have leant is just preparing a slide well doesn't mean it will show the things they want to see.

Titrations

Achieving the end point of a titration is one if the hardest things to do I think in chemistry. It does take lots of practice to do this, so instead of doing this experiment once we did it 20 or so times. Know the students are excellent at doing titrations.

Magnetic Fields

 Comparing the magnetic fields to the electric fields around wires as the A level students learn how electricity really works, in fields not by the drifting of electrons.

Making electric fields

 Take a dash of semolina in some olive oil, then add a few volts from a wimshurst machine into two parallel wires and we have an electric field

Maths - revealing the solution

 Revealing the solution one line at a time to show the students how to solve the problem. Their only complaint that I reveal the answer just after they have done that bit. At least they know they are correct so far

Simple Harmonic Motion

Playing with my favourite topic simple harmonic motion today, using a
@pascoscientific force sensor at the top and a protected ultrasonic motion detector below

 

Mounting a force sensor

 We use a Manfrotto friction arm with a lighting stand adaptor to mount the @pascoscientic  force sensor as it gives a degree of movement both vertically and laterally to get the force sensor in the correct position
