In conjunction with “science lunch,” organized by teacher Katie Guilbert, I helped Bella Romero 5th-graders complete research projects.
2012-2013: We set up tanks with different guppy populations and a tank with a cichlid predator so that the students could study predator-prey interactions and compare artificially selected pet store guppies to wild-caught ones. The students designed a unique experiment, stated hypotheses, made data sheets, and collected data over a 3-week period. They entered and analyzed their data and presented the project as a poster at the Front Range Student Ecology Symposium in February 2013. *Pictures*
2013-2014: We set up tanks of native and pet store guppies separated into males and females. The students designed an experiment to look at feeding preferences. They fed the guppies 5 different types of food for one month and recorded the amount of each type of food the fish ate and how long it took them to eat it. They had several hypotheses, for example that females would eat more than males since they are almost always pregnant, that pet store fish would eat faster than native guppies since they do not have to worry about predators, and that pet store fish may have evolved different preferences after many generations in captivity and lots of artificial selection from breeders. They summarized their findings in a poster that they presented at the Front Range Student Ecology Symposium in 2014. *Pictures* *Pictures from FRSES 2014*
