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

Using a Fuel cell

 Using a dual fuel cell to split water into hydrogen and oxygen from solar energy and then to reverse the system and power a fan from the same hydrogen and Oxygen #iteachphysics

Using a Baffle to improve a ripple tank results

 One of the problems with using a ripple tank is unwanted reflections. Simply placing a piece of paper towel stop the unwanted reflections leading to better and clearer results. #iteachphysics
