Yr 9 Semester 1 revision

Revision outline

How to study Science
1 make a glossary - every topic has a guide sheet - in the guide sheet there is a list of words and terms you should know -
2. Collect your notes - the guide sheet is a course outline that lists the main concepts you should learn and the main activities you should do. You should build your notes from your text and your notebook - but make sure you have information on each of the ideas listed in your guide sheet.
3. Summarise your notes - a good summary will include diagrams and experiments that summarise the key concepts of each topic
4. convert all this into a concept map - you are aiming to get it down to a half page for each topic. Don't worry if yours is a bit bigger

Before the exam -
  • get friends to test you on the glossary,
  • try to redraw the diagrams in your summary.
  • complete test and / or practice questions.

old revision notes not for this year



STELR
Be able to trace the energy transformations in a system - eg Light energy to electrical energy in the solar cell.
Be able to describe the energy transformations in a system eg a butterfly flying - potential chemical energy in food converts to kinetic energy of wings flapping .
Be able to explain potential energy or stored energy.
the greenhouse effect is the warming or stablisation of temperatures caused by gases trapping infrared radiation or heat. Examples of green house gases are CO2, water, methane, Be able to describe the enhanced green house effect as the increase in production of greenhouse gases leading to an increase in global climate change.
Non renewable resources include fossil fuels - we say they are non renewable because it has taken millions of years to convert the vegetable and animal matter into gas, coal or oil that we further refine to use as petrol etc
renewable resources are solar energy hydroelectricity, wind energy tidal energy.
Compare energy efficiency and calculate energy efficiency.



Responding and controlling
You should be able to label and describe the function of diagrams of the following - reflex arcs, neurons, Brain, Feedback loops for water regulation and Blood glucose concentration ie insulin release and manufacture.

Forensics be able to describe different finger pints and ow they are formed and lifted. Describe the advantages of DNA over Fingerprints and blood typing at a crime scene. In particular that evry person has unique DNA and this can be used to identify them - they leave traces in salva, blood, skin etc
Be able to recognise an example of an observation and an inference in the way scientists work and think about a problem. eg observsations are made from what they see or measure (use of sense) an inference is a deduction based on these observation - 'I found cat fur on my coat' this is an observation - my coat was near the cat - is an inference, that I have a cat is an inference that needs more evidence to support it.
The presence of insects on a decaying body can give a timeline of the death - because different insects take different amounts of time to hatch. - review the online forensics you did
Blood spatters can indicate the force of a hit or the direction of the blow - these are indicated by the size of the drips the distance they are spattered the amount of spatter and the volume of unspattered blood, blood types. DNA, review the incursion from Gillian the forensic scientist.
