# Good luck!

Good luck to all the Chemistry Standard Grade students who have the dubious honour of kicking off this year’s SQA Exam schedule on Thursday morning!

Remember your monkeys eating peanut butter!

# 7 day count down!

The Chemistry Standard Grade exam is on Thursday May 1st – exactly 7 days from now!

All pupils should already be working hard on their self-revision – and bringing in any questions or problems or requests into class during the day, so that teachers can advise or assist.

Please remember that there are a number of resources available to you in making your revision rigorous, varied and worthwhile. These include:

• Past Papers
• Revision guides
• Bitesize books and website (www.bbc.co.uk)
• Teacher worksheets
• Evans Chemweb (see link from here)
• Peer revision – get together with a classmate and test (and learn from) each other!
• After school revision (the Wednesday 3.45pm classes have run all term)

Good luck with your revision! Remember the short term pain working at home for this coming month will be worth it – your exam marks will reflect your effort in revising!

# An Archimedes riddle…

Archimedes was no slouch! The Greek mathematician was also a physicist, engineer, inventor and astronomer in his spare time!

He is most well known for his “Eureka moment”…

The most commonly related anecdote about Archimedes tells how he invented a method for measuring the volume of an object with an irregular shape. According to Vitruvius, a new crown in the shape of a laurel wreath had been made for King Hiero II and Archimedes was asked to determine whether it was of solid gold – or whether silver had been added by a dishonest goldsmith. Archimedes had to solve the problem without damaging the crown, so he could not melt it down in order to measure its density as a cube (which would have been the simplest solution).

While taking a bath, he noticed that the level of the water rose as he got in. He realised that this effect could be used to determine the volume of the crown. For practical purposes water is incompressible, so the crown would displace an amount of water equal to its own volume. By dividing the weight of the crown by the volume of water displaced, its density could be obtained.

In other words, the density of the crown would be lower if cheaper and less dense metals had been added…

Archimedes then took to the streets naked  (so excited by his discovery that he had forgotten to dress!)  crying “Eureka!” (“I have found it!”)

So what is your Archimedes Riddle?

You are sitting in a rubber boat in a swimming pool. In the boat lies a stone. You throw this stone from the boat into the pool. Will the water level in the pool rise or drop?

Over to you…

# Chemistry Easter Revision

Class 4D will spend the rest of this week catching up with any unfinished practical assessments – this is due to the Live-N-Learn Workshops for S4 There will be Live-N-Learn Workshop for S4 pupils over 2 days – 16 and 17 January. They will affect our lessons on both Wednesday and Thursday morning. However, the workshop aims to equip pupils with study skills to help them prepare for their final exams in May. So make the most of the opportunity…

# Chemistry Resources

REVISION RESOURCES – IDEAS TO HELP YOU REVISE FOR CHEMISTRY

BBC BITESIZE can be found as part of the BBC website – or in hard copy. The Standard Grade Chemistry Bitesize Revision textbook can be an invaluable revision resource.

Evans2chem website, run by Preston Lodge PT Chemistry, Mr G Evans, is also a resource that we encourage our pupils to use – the ability for the classroom teacher to get emailed feedback from the website as to how any of their students have done in an online assessment is invaluable.

The Revision Aid website provides a number of links to on line resources including Doc Brown’s Chemistry Clinic and Revise Guys…

PRESTON LODGE CHEMISTRY REVISION CLASSES
run every Wednesday after school in Mr Evans’ room. All welcome.
