There is now in and out trays inside the science staff room.
Place your homework on the top one, and take the corrected work out the bottom. There is a sign in book where you can write in what you wanted corrected, and will log comments.
From the Practice Half yearly here are some hints:
Good and Bad eddy currents- the bad ones are from coiled extention leads, losses in anything AC electrical.
When you have a question, draw realistic diagram. If you draw a 20 deg triangle you can see that the horizontal velocity has to be bigger than the vertical
Torque is a vector quantity
Work done on an object is the amount of work put into an object, done by an object is the amount of work out.
It is now a requirement to circle the verb in a question. Then use it the answer. If possible use a table.
A comparison table has Three columns Object one, Object two, Comparison of Object one to two.
Four columns are even better where you list the concept in the first.
Compare Earth and Mars gravitational effects
G Effect Earth Mars Comparison
g 9.8 3.6 Earth is bigger
Atmosphere Large Small Mars has lost is atmosphere
escape V 4000 1000 Mars is smaller
About Me
- drhill
- I come from a Science family: My father Geoffrey Hill was Australia's first computer programmer on CSIRAC the fourth computer in the world. He is credited with invention of Computer music and the development of “Interprogram” a language before Basic. My PhD is in Atomic and Molecular Physics. I have researched the activated oxygen layer above the ozone layer, and 'Assigned' the world's smallest molecule. At the University of Toronto I researched high power UV lasers. I have specialized in automation in fibre optics. This developed into research in Machine Intellect and Robots. I have enjoyed work as an Explainer with Questacon and my time as a part-time soldier. I currently teach High School Science at Epping Boys’ High.
