Every year the examiners' report mentions problematic Investigations, those which are unethical, or standard labs which are not applied to any specific interest. Personal engagement, Exploration, Analysis, Evaluation, and Communication are the criteria against which the investigation is assessed. Dependent Variable: Ethylene levels, CO2 production, qualitative assessment. Change the different conditions in which the plants are found as well as the species. This is a nice wet laboratory project and there are some simple ways to measure the growth of the bacteria but these can be fiddly to work out, and concentrations of bacteria used in inoculations will need working out. You have to show that the data has been carefully selected, and that measures have been taken to ensure that other factors which might affect the data have been controlled, by careful selection of the data used.

How do natural antiseptics (ginger and turmeric) compare with commercial antiseptics in the inhibition of growth of e. coli bacteria? Some assessment of the reliability of the sources will be needed and some discussion of ethics of using someone's data, with their consent, hopefully. Paper 2 contains short-answer and extended-response questions on the core (and Additional Higher Level (AHL) material . This investigation could be a nice way to combine two standard procedures, one to estimate the rate of respiration in the soil and another to estimate the rate of growth of a plant. Other possibilities are paper simulations, e.g. 6 years ago. An ideal IA idea is one that reeks of originality and leaves room for proper investigation and analysis in the process. These are just some of the questions which will need answering. An important thing to note here is that although you are allowed to take inspiration from existing research, papers/journals, you are expected to give a novel perspective to the idea while producing it in your investigation.

Controlling other factors which affect germination and collecting a large enough data set will also be good challenges for a Biology student to work out. using potassium permanganate and heating, from a protocol from Science & plants for schools. 3.2 The More Data, The Better. This investigation is a bit biochemical and the answer to simple research questions about the hydrophobic / hydrophyllic properties of photosynthetic pigments themselves would be a little bit obvious, so the challenge is to thing of a research question that could be answered by mixing petroleum ether (a nonpolar solvent) and propanone (a polar solvent) in different proportions and calculating retention factors. should include all the normal conventions of d.p. 5 years ago. Some plants grow well in coastal soils with igh salt concentrations but others don't. , its objectives, partwise breakdown, and what IB expects of you. To measure the rate, you can either measure how quickly different species grow, or one of the other factors described below. To make things as simple as possible for you, we've put together a list of biology research project ideas. The different pH levels are pH 1, 3, 5, 7, 11, and 14.
