It's been such a long time....

Since the last time I was able to blog I was finishing up my yogurt project. I have now been involved in a different project which consist of things, in my opinion, more disgusting than rotten milk. My project is to determine whether temperature has an affect on the respiration of different insects. So far I have been able to test this hypothesis out on crickets and worms, in the temperature of cold and room temp. Here is a little bit of my results:





Graph one:  Worm's Oxygen levels at room and cold temp.



Graph two: Cricket CO2 levels at room and cold temp.



What these graphs basically show is that as temperature decreased so did the respiration of these insects. Although I did feel bad for possibly killing off half of the crickets in the Phoenix (not really, don't worry) but I did end up getting some useful results. The bars that are found on the graph are called errors bars and what these bars indicate is that the majority of my data results are found between these lines. What I was taught was that if these bars would have overlapped then my results would've been insignificant. These bars state that there is a significant difference between the two sets of data and that is a good thing. :)

The way that I tested this out is through a device that records the levels of Oxygen and CO2 for 10 minutes creating a graph and giving a slope. I ran this device 10 times on a set of 6 crickets then 6 worms in both a room temperature and cold temperature (on ice). This gave me a set of 40 different slopes, which I averaged to get four individual slopes which then became the data that helped me create four different graphs, similar to the two above. I am very happy to report that I do not have to kill anymore insects, hopefully.
