Up to 3 fragments may be cloned at a time (can you replicate that in the lab?).

Third, you are to compare your cheese to a similar commercially available cheese and report on the differences and likely causes of that difference. (The factors that you can compare will be those that you have defined in the second section above). A copy of this cheese EEI is available for download . A useful video from the ABC TV program maybe worth watching.
One of the most disappointing laboratory experiments you can find is the steam distillation of these oils from leaves. They never work very well and you usually end up with a disappointing emulsion - not clear oil. For a good EEI you would need to do more than just extract some oil; you could have a go at improving the method by trialling different heating and collection methods, different aged leaves and so on; all carefully thought out and justified - not just trial-and-error. If you are stuck you could look at oranges or cloves. A trip to an olive leaf distillery would be a fun day out. The photos would look good in your report.

You could make up a solution of known concentration (recall that CuSO4 is actually in the pentahydrate form CuSO4•5H2O when working out molar masses). Just measure the absorbance of it (the lambda max for the copper solution is 740 nm) on the spectrophotometer and from a graph (assuming the Beer-Lambert Law is still working from 1852) and if you know the absorbance you can work out the concentration of the copper ions. Your teacher may suggest that you prepare a range of standard solutions of Cu2+ to produce your own calibration curve.
This suggests a great EEI. The hypotheses are obvious from the above, but it is the measure of light intensity that needs care. Judging brightness with your eye is difficult and not that accurate. You may have a light intensity probe available with some of the datalogger kits. If not, you could use a light dependent resistor (LDR) such as the ORP-12 for which there are calibration curves of intensity vs resistance (see below). The key think is to get absolute darkness as you don't want ambient light (room or sun) getting in.

I selected links that provide background information aboutphotosynthesis and links that explain some of the equipment and techniquesthat we will use to investigate photosynthesis.
I recommend that youreview the links on light, chromatography, pigments (chlorophyll and carotene),and absorption spectra as you prepare for lab and as you write your reportson your observations.

For teachers who would like to have a basic introduction to wine chemistry or would like to have a refresher, the Queensland College of Wine Tourism at Stanthorpe offers a professional development workshop that may be useful. No recommendations are made as it is up to teachers to check it out (but reports have been good). It is called the "Teachers Wine Chemistry Professional Development". Teachers are provided with an overview of the wine production process and the chemical processes/analysis that are conducted at each stage of wine production with an emphasis on the importance of chemistry concepts to quality wine production. The other program of interest may be the Senior Studies Wine Chemistry Residential Program for Year 11 and 12 students doing a wine chemistry EEI. It is a 2-day practical program delivered by a qualified winemaker and costs $90 per person (meals and accommodation extra). No recommendations are made here but more information is available for or on their .
