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

Using a Demo eye

Using the @pascoscientific demo eye to practically look at how the lens in the eye works by changing shape, and looking at different lenses for long and short sightedness. I really great bit of kit. #iteachphysics

Repairing Lung Machine

After a few years of use my lung demo broke, but with a new y piece, new balloons and new elastic bands and gaffer tape the lung demo has been rebuilt and is again working well, to demo to more students.

Using Mechanics to help with A level Maths

 Doing practical mechanics to help understand A level Maths. Playing with practical mechanics brings a level of realism to the Physics Maths problems, so the students can see and feel what is going on.
