[/quote] i´m not sure if i can help you or not but at least i´m gonna tell you on what i´m doing it so you can have an idea. i did an experiment on pain tolerance and pain threshold. basically, i used my classmates to see how much they could resist with their arms in water at 0º C. i measured their pulse, their blood pressure and temperature before and after the experiment. i think it´s a pretty interesting one, cos for example people from norway or finland stayed inside the water for like 30 mint while people from the south like croatia stay for only 5 mint. did that help?

Gwib Posted July 27, 2008 Report Share Posted July 27, 2008 Choose one where you can get lots of statistical data for interpretation and graphs. EG something where you can measure something (pulse, reaction time, water level, weight etc) Reply Link to post Share on other sites More sharing options...
angeliqwings Posted August 1, 2008 Report Share Posted August 1, 2008 (edited) i just completed my EE in biology!! yay! im so glad i finished it!! why dont you try microbiology???? a few ideas: 1. investigate the effects of antibacterial cleaning agents on removing bacteria on a specific surface 2. something on enzymes and creating youghurt 3. investigate the effects on heart rate?? investigate a factor of seed germination (use something like peas or radishes as they germinate v.fast) try something in ecology, something about your local surrounding enviroment, as it will be original and IB will like it. e.g. look at the types of bacteria found in local lakes and their effects etc. Perhaps you could ask your supervisor if they have any contacts with any uni students who are runnning an experiment, help them out with it and they could give you all the info you need!! (some of my friends did this!! didnt turn out to be that bad!!) well here are just a few ideas!! hope you figure it out!!

mania90 Posted August 1, 2008 Report Share Posted August 1, 2008 You can also do sth on respiration and factors influencing it. use your classmates to see how it varies dependently on sex, hight, being a sportsman or being a smoker after physical activities and in different positions, ex sitting lying standing on your head this may be too simple buts its a suggestion from person doing ee in physics so it dont have to be professional. i know that my classmates done sth on nodule bacteria, mould and such things Reply Link to post Share on other sites More sharing options...
