Nitrification in nature is a two-step oxidation process of ammonium ion or ammonia to nitrate ion catalyzed by two types of bacteria.

Place the mold solution on a nutrient agar plate and incubate for a while. Add 50g or sugar to the liquid and make up to 4. This approach is fairly common in Year 11 as it allows students to concentrate on particular aspects of the EEI and to develop investigative Thesis aquatic hyphomycetes prior to an "open inquiry" approach in Year You can see how it has gone white and opaque.

The field investigation, carried out in late summer and early autumn, is of the flora and spora of 7 lotic sites of differing character, including a main river; certain of its tributaries, and a woodland stream.

My thanks to Biology teachers from Nanango for sharing this. Even after flood waters recede, the residue left behind contains the same micro-organisms. Remember that weak acids phosphoric, citric are not fully dissociated in water so their pH is not that low but they gradually release more hydrogen ions as they react.

Does the addition of certain minerals affect the digestion rate of milk, such as PhysiCAL? Year 12 student Mitchell Oxley from Redlands College, Brisbane, found this was too weak and stepped it up by a factor of No single disinfectant is ideal.

That suggests waterlogging your potting mix samples to prevent the bacteria getting oxygen and comparing them to the control.

However, many teachers have found strategies to manage this should they choose to opt for a Open EEIs. Whilst students may choose various aspects of physiology, such as rates of photosynthesis or respiration, membrane permeability or diffusion rates, a popular experiment involves enzyme activity.

The flavour, aroma and texture will ultimately be affected. There are lots of other methods. There are lots of other methods. Sieving gets rid of the larger bits of organic matter.

The time-consuming nature of the practical work and the difficulty in obtaining quantitative results are often offset by the quality of scientific techniques required, the scope for constant improvement of the method and the creativity required to transform qualitative results into a quantitative scale in order to make meaning of the results.

A good EEI may be to look at the effect of drink acids on teeth. A good EEI is to assess the effect of a variety of antimicrobial disinfectants on bacterial growth.

Lastly, what sort of yeast is best?

The flasks at the end point. But your body is full of bacteria, both good and bad. Add 50g or sugar to the liquid and make up to 4. A study by Fraunhofer and Rodgers found that the rate of enamel dissolution of teeth was not dependent on pH but may be affected by titratable acidity.

This section of the work will also require you to define which factors you can reasonably test in a school-laboratory, and which variables in the production that you can vary.

Teeth are a form of hydroxyapatite Ca5 PO4 3 OH but you can simulate this in the lab with calcium carbonate marble chips. This approach is fairly common in Year 11 as it allows students to concentrate on particular aspects of the EEI and to develop investigative techniques prior to an "open inquiry" approach in Year Examples of Risk Assessment forms can be found in the tasks available on this page.Many of the suggestions below involve the use of animals.

Various laws apply to the use of animals in schools particularly any "live non-human vertebrate, that is fish, amphibians, reptiles, birds and mammals, encompassing domestic animals, purpose-bred animals, livestock, wildlife, and also cephalopods such as octopus and squid".

General. Mycological Progress is a peer-reviewed, international journal on all aspects of fungi, including lichens. It publishes original articles, but also welcomes reviews and methods papers on the taxonomy, systematics, evolutionary biology, cell biology, ecology, pathology and biotechnology of fungi.
