Why Don’t Whales Have Legs? SBI4U1-03 Vink Maria Hoang Hypothesis: The whale with "blubber" or the plastic in the styrofoam will lose heat or cool slower than the glove and the plastic baggie because the "blubber" allows for the whale to stay warmer and retain the heat more than the other two kinds of whales. Materials: Container that holds water (e.g., deep plastic ray or large plastic beaker) 1 latex or plastic glove 2 small sip-lock type plastic baggies 1 250mL graduated beaker 1 Styrofoam cup (large enough to hold full plastic baggie) Hot water (or way to safely heat water) Cold water Thermometer Controls: Time Temperature Amount of water Temperature of Ocean: 20.2 °C Temperature of Whale: 57.7 °C Amount of H2O in the Whale: 150 mL Procedure 1.

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
