As the cell membrane disintegrates, alcohol can then enter the cell and . Well, you can try to model bacteria growth, cell division. There needs to be some clear links to the biology of blood pressure and how exercise affects it. [], or you can call us here at: +44 20 4571 0455. This sounds like an easy investigation but it is tricky because first there needs to be some biological reason why the heart should speed up in the presence of music and this is impossible to explain with IB Biology. In paper 1 there are 30 (at SL) or 40 (at HL) multiple-choice questions. The data must be analysed by the student and tables / graphs etc. For strict autotrophic organisms - Only inorganic compounds. 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. By testing people of different ages to see if there is a difference in their reaction time it may seem like a simple study, but there are a lot of factors which need to be controlled and it will be difficult to find enough participants to create a large enough data set. Ensuring that there is enough data will also be important as there are likely to be quite a few other factors which will need controlling or considering at least. 30+ New IB Biology IA Ideas.

They cause our teeth to rot, shaping plaque and causing awful breath. Lots of scope but not an easy investigation to complete in the time, in 12 pages. Your Research Question and the Aim of the Investigation are separate sub-headings with different implications. There may be a combination of roles for plant roots and bacteria in the substrate and both of these link to the nitrogen cycle and so would allow for a detailed hypothesis and a focused research question. A limitation with an experiment that finds the relationship between sodium ion concentration and the rate of neurogenesis in the hippocampus of the brain is that its results are not applicable to other parts of the nervous system. It might seem like a lot of work, but with the right topic in hand, you will go beyond your expectations! How do halophyte seeds respond to increasing salt concentrations compared to normal seeds? The following examples are not unethical, but just not very good, because the data is rarely enough for a good analysis and difficult to control. Some of the challenges of this type of investigation will be controlling other factors which affect the growth of plants. I'll do so in a series of questions that will help you probe deeper into your IA. Can the max performance be measured best using max heart rate or maximum speed? How does different conditioners affect the strength of hair? Other possibilities are paper simulations, e.g. Neither should the idea be too generic and nor too simplistic. classes to learn/preach! This would be a challenge and it would require some research before beginning. Test the stomatal density of different leaves exposed to variable conditions using a microscope. The existence of living organisms without cells. Some plants grow well in coastal soils with igh salt concentrations but others don't. Using nationally published data on epidemiology and weather data is certainly possible and it could happen that there are correlations between climate and some disease outbreaks this will need explaining in terms of the mechanisms of transmission of the specific disease. Follow the steps here to extract the DNA. However, keep in mind that even though we are doing our best to maintain this list fresh, other students will find it as well. How does the acidity of different beverages affect the deterioration of tooth enamel? If you are still not dissuaded then be sure to collect enough data and try to be analytical, don't mix types of music and tempos of music and try to keep the investigation to some biological cause or effect. reply. Student work is internally assessed by the teacher and externally moderated by the IB. What is the most effective way of fighting an endemic?
