This investigation will attempt to prove, whether or not a change in temperature will affect the respiration rate (and therefore the breathing rate) of a locust. Locusts are 'poikilothermic' and I will be taking this factor into account when predicting the locust's reaction to a temperature change. Preliminary Testing Preliminary tests consisted of a 'mock experiment', a kind of trial run of the real thing. The test was carried out as follows: · Fill a beaker with water of the desired temperature · Place the locust in a boiling tube and place this in the water · Observe the number of times the locust's abdomen moves up and down and record the breathing rate over a period of time · Repeat for different temperatures These 'basic' preliminary tests uncovered a few 'flaws' in the experiment and helped to highlight a few aspects that needed careful consideration. Aspects that will need to be altered are, the length of...
