I wanted to conduct an experiment to see if listening to music will increase physical activity in hamsters! I came up with the following hypothesis, variables, and methods, and even listed the resources I used to inform my research. My results and conclusion are included below. Question: After reading the following information, list 3 things this research project did NOT do well and why (be specific about how you would recommend improving it).  Hypothesis: Hamsters exposed to pop music will run more in their exercise wheels than hamsters not exposed to music. Independent Variable: Exposure to pop music (Taylor Swift playlist vs. silence) Dependent Variable: Total wheel revolutions per day Controlled Variables: Cage size, wheel type, food/water, temperature, light cycle, breed (Syrian hamsters) Method Summary: Four hamsters (2 male, 2 female) were divided into two groups: Music group (n=2): Exposed to pop music for 3 hours daily using a Bluetooth speaker. Control group (n=2): No music exposure. Wheel rotations were measured with a basic pedometer attached to the wheels over 7 days. Research Sources Used: PetOwnerLife.org (2021). *Do Pets Like Music?* @MusicForAnimals TikTok videos Thompson, A. (2005). *Animal Behavior in Captivity*. Small Mammal Journal, 14(2), 88–91. Interview with local pet store employee Personal observations from the researcher’s younger sibling Results: Music group average: 3,420 wheel rotations/day Control group average: 2,950 wheel rotations/day       Conclusion: Researchers concluded that “music might increase physical activity in hamsters.”

The similarities in cell structure and DNA between very different species (like oak trees, whales, and bacteria) can be explained by evolution from a common ancestor.
