you should see a little animation here. it’s what’s going on inside the alveoli in your lungs. oxygen and carbon dioxide are being exchanged across the thin walls of the alveoli.

here’s a few links to show what happens when primary colours are mixed. the last one is the best.
first, second, last (and best).

absolute zero is a term used in science to define a point at which the motion of particles which constitutes heat is minimal. that temperature is -273.15°C or zero kelvin. degrees kelvin are named after the physicist sir william thompson, lord kelvin (1824-1907), who first worked out this point.

The dane anders celsius decided the point at which water froze was the ideal base for his scale of temperature. lord kelvin decided to maintain the celsius scale but make the starting point the coldest temperature possible to achieve. thus absolute zero is 273.15°C lower than water’s freezing point.

at absolute zero strange things are hypothesised to happen to matter. It is known that the hotter a substance is, the more energy it has and the more the molecules jiggle. The colder the temperature, the slower the molecules move and at absolute zero the molecules do not vibrate at all and the matter contains minimal energy.

this diagram shows three ways of explaining the same thing.

here’s a load of resources for teaching 8i (heating and cooling).

here’s a link explaining how thermometers work as well as information about other ways of measuring temperature.

here’s a link to word searches for every ks3 unit from 7a through to 9m(!) all in pdf format and ready to download.

really good website from nottingham university showing short video clips about each element. includes some of the rarer ones. unfortunately blocked in school but well worth a visit at home. thanks to mr rogers for the link.

here’s a load of resources for 8a. some are projectable for use in classrooms. this one is particularly good.

for 8C4
produce a powerpoint presentation, word document or publisher document about these important pioneers in the world of vaccination and immunology.

here is the reource material for 18.6.08 engineering fortnight one day project for year 8 form 8yn

this project is for the whole morning
you can choose as many as you wish
you could do all…or just one…but all must be done in one morning (there ‘might’ be some time later on but don’t bank on it). get it done by lunchtime.

design a survey to find out about peoples tastes in personal care products.
design a new logo for ’soap ‘a’ sonic’
here’s the current one:

try to answer these questions: what is soap? look at the history of soapmaking, what is and how does ’saponification’ work, the story of port sunlight village, the life of william lever and lever brothers, the pears soap story, ivory ‘floating soap’, do some research into soap prices at local supermarkets, how are soap powders made? what’s the difference between ‘ariel’ and ‘persil’? what do proctor and gamble ltd do? how much do soap powders cost at local supermarkets?

lots to choose from…lots to do…now get cracking
