Van de Graaff generator

Using the Van de Graaff generator is probably one of the most iconic experiments in Physics. Had a lot of fun playing with this and explaining what and why it is happening.

Waves and their properties

 Looking at moving a Ping pong ball using sound waves from one tuning fork on one resonance box to another.

Centre of Mass

Now the students know why I have a hanging basket hanging in my classroom. They walk under it every day and never say anything until we do Centre of mass.

Osmosis

 Looking at the properties of Visking Tubing, The students looked at how it can be used in dialysis using counter flow theory and designing their own dialysis machines.

Shaking Beads

Shaking some beads with a Pasco Wireless Thermometer and showing that the temperature rises with vigorous shaking as show on the Capstone display. This gave the students immediate feedback to help them see what is going on and explain some laws of thermodynamics.

Electric and magnetic fields

 

Looking at the effects of an electric current flowing in a solenoid on a compass.  The A level students are learning about the similarities and differences in electric and magnetic fields, plotting the magnetic fields and using probes to get actual data on this.

Pasco lens for the Demo Eye

The Pasco Demo Eye has a "real" style eye which allows by the addition or removal of water which makes the lens get fatter or thinner in a similar way to the ciliary muscles pull on the lens in an animal eye. Great for Biology and Physics #iteachphysics
