You know that Spring is here when the constellation of Leo the Lion is in the southern sky.
Notice the planet Mars underneath the constellation.

Hi Physics lovers,
Here are a few links on this wonderful topic:

This video is a recap on what happened in the lab this afternoon when Mr. McKenna, the technician, demoed the electroscope discharging when UV light was shone on the zinc plate on top of the electroscope.

This is a fantastic piece of simulation software from PhET which allows you to build electric circuits and study what happens when you change resistance or voltage.

Download the simulation by clicking on the picture.

To get you started why don`t you build this circuit
Investigate:

1. How the current in the circuit changes when the 8 ohm resistor is doubled
2. How the voltage will change across the 24 ohm resistor when the 8 ohm resistor is doubled.

Have some fun building more circuits and investigating the the current, voltage and resistance of the circuit.

My S2 class took part in a note taking exercise. They were asked to work in threes and research information on microbes.

After discussion in their respective groups a recorder had to write down the key facts they had found in their research.

Photographs were taken and uploaded into a Google Docs presentation document.

The slides from the presentation were printed off and each pupil then pasted the classes notes into their notebook or can look at the notes here.

A couple of white boards and pens and a research task and my S2 pupils set of to pick up information around the class on microbes.

They recorded their information and in groups they had to decide which piece of information had to go on the small whiteboard.

I then took a picture of each white board and made this presentation with google docs.

You can try out different situations where light is refracted. Have fun!

My fellow physics teacher Mr Mackenzie from Thurso has produced a wonderful little movie summarizing what we talked about last day in physics, namely Total internal reflection.

I will let Mr Mackenzie explain:
