A vce classic
In the rigorous journey of deducing the structure of DNA, one stormy night in 1953 (ok- I don't really know if it was stormy, but for storytelling purposes just go with it ) scientists James Watson and Francis Crick analysed x-ray diffraction images taken of DNA, curious of its true structure. We should also just appreciate that predictions or hypothesis are often the catalyst for performing these experiments, for example. Thus while predictions are not an official (I only speak for VCE Chemistry as I studied it) section of a VCE Chemistry report, they are necessary in developing an insightful discussion into the concepts involved and the significance of our results- especially if one contradicts the other. Our preconceived ideas of the chemistry (or biology or physics) can dictate what we are experimenting, and how the practical is structured.
In science experiments, making predictions have a significant influence on how we view the science we are exploring. Predictions/hypothesis (credit to wyzard): “To use gravimetric analysis to calculate the mass of sulfur as sulphate in a sample of Yates ‘Thrive’ fertiliser, and therefore verify the authenticity of their statement that their fertiliser’s sulfur content in their fertiliser is 17%.” Not much to say here- often if your teacher hands out practical sheets (containing method and materials), on there is a quasi-aim I often just rewrote.Įxample (from Unit 3 SAC 1b report- on Gravimetric analysis): The number of successful collisions is dependent on different factors in this experiment the variables particle size, temperature, and concentration will be tested via an acid-base reaction between sodium hydrogen carbonate and citric acid, both which are ingredients in effervescent antacid tablets.”Īim: Usually here all that’s required is a couple of sentences describing the practical’s purpose. Thus the rate of reaction can be seen as the number of successful collisions in a given amount of time. The collision theory dictates that in order for a fruitful reaction to occur, the reactant particles must collide, and with enough energy to overcome the activation energy barrier- the energy required to break reactant bonds so new ones can form. “Different reactions occur at varying rates, due to a range of contributing factors, which at an atomic level is explored through the Collision Theory. For our criteria sheet anyway, the intro was mainly for providing a brief preface, and wasn’t worth that many marks.Įxample (from Unit 4 SAC 1 report-on Collision theory):

Personally my teacher liked introductions fairly to the point, and full of chemistry lingo. In this sense, provide the experiment’s context by introducing the chemicals used as well. Introduction: Here I provided a rather general summary of the investigation, defining through the specific context of the experiment the analytical technique for chemical process involved. There are often people who know the content back to front, but have difficulty explaining/communicating it on paper- so here’s some things that worked for me- organised into each “part” of a practical report. Practical reports, on the other hand, require a more theoretical (imo) understanding of the chemistry behind the observations in an experiment, and writing skills become a pretty significant factor. So what makes practical reports so different? Well although both types of SACs seek to critique our overall understanding of the underlying chemical concepts, tests/exams tend to focus more on short answer questions, often simply with numerical answers, or concisely written explanations.
Now from experience, the skills in writing these reports and performing well in tests/exams are actually quite different, and performing well in one is not always conducive to performing well in the other.
