- antimicrobial activities of ginger, honey, green tea etc. by measuring the inhibition zone using the disk diffusion method (you can find loads of samples online, it's also the most common bio EE's)
- plant hormones, photosynthesis/cell respiration, factors that affect plant growth
- something to do with gel electrophoresis and DNA fingerprinting if you have access to the equipments
- animal behavior (which is what I'm doing - on mealworms, previously people have done it on woodlice, turtles, hamsters), although most people will suggest you avoid these topics because of the amount of uncontrolled variables and how unpredictable it can be, also lots of trials which can be tedious
- something to do with exercise, heart rate, physiology
