Introduction

Coursework Animal Behaviour * The effect of temperature on the speed of mealworms (or woodlice) * The effect of light intensity on the distance travelled by maggots (uses fluorescent paint and a dark room) * The effect of light / dark or dry / humid conditions on the movement of woodlice (could be numbers in a choice chamber or speed of movement) Animal Physiology * The effect of caffeine / coca cola / alcohol on the heart rate of water fleas Daphnia (video microscope really makes this easy) Ecology (school grounds etc.) * The effect of aspect on leaf area (e.g. beech leaves from either side of a hedge, bramble, bindweed all work well) * The effect of acid rain on snail shells (use empty snail shells from grounds and dil acids, weigh before and after) * The effect of pollution on lichen growth (choose 2 sites: one polluted e.g. city centre, staff car park --- one clean --- control aspect and substrate e.g. choose south facing limestone walls --- measure lichen areas with quadrats) ...read more.

* The effect of bead size / enzyme concentration / substrate concentration / rate of flow on the reaction rate of an immobilised enzyme (see above) * The effect of calcium chloride concentration on the clotting of milk by the enzyme Rennilase or equivalent Human Physiology * The effect of smoking on lung capacity (would need some honest volunteers --- smokers needed, but not allowing them to smoke for the experiment) * The effect of drinking (e.g. coca cola or equivalent) on reaction times * Is there a correlation between height and hand span / finger length / foot size, or any other body part * The effect of different types of items on memory (use sequences of letters, numbers, words) * The effect of aural vs. visual memories * The effect of distractions (whatever you like!) on the ability to memorise sequences Microbiology * The effect of different brands of toothpaste / mouthwashes / antiseptics / disinfectants on bacterial growth * The effect of different yeast strains on rate of fermentation * The effect of different substrates e.g. ...read more.

Conclusion

use the SAPS practical with algal balls --- Scenedesmus --- great fun, but you need to grow enough alga --- check the SAPS website for details * The effect of temperature on how much colour leaks out of beetroot * The effect of upper vs. lower surface on the number of stomata (can be microscope investigation or simply put leaves into very hot water and count bubbles --- comparison of light vs. shade * The effect of freezing on germination success * The effect of allelopathy * The effect of heavy metal pollution on germination / growth Plant Physiology * The effect of light intensity on photosynthesis) use the SAPS practical with algal balls --- Scenedesmus --- great fun, but you need to grow enough alga --- check the SAPS website for details * The effect of temperature on how much colour leaks out of beetroot * The effect of upper vs. lower surface on the number of stomata (can be microscope investigation or simply put leaves into very hot water and count bubbles --- comparison of light vs. shade * The effect of freezing on germination success * The effect of allelopathy * The effect of heavy metal pollution on germination / growth ...read more.

    This provided me with the best quadrat size to use for the experiment that will produce more reliable results. Another factor that needed to be considered was the length of the transect line or interrupted belt transect. To produce enough data for a potential statistical analysis and kite diagrams the length chosen was 600 metres.

    Due to the larger the concentration of the streptomycin this shows that the rate of reaction was faster and it proves this within the results table. This is something that should have thought about before carrying out the pilot study and may have therefore helped to obtain more accurate results.
