rivers and lakes. Although no life has yet been found on other planets, it may be possible for some form of life to live on another planet in our solar system, and scientists are continually brainstorming what life might be like on a different planet than Earth. In this activity, you will create an organism that could live on another planet. Follow the guidelines to develop your organism, and be creative! What you will do 1. Choose any of the planets in our solar system, except Earth. 2. Develop an organism or animal that can survive on this planet. Make sure you explain how your organism overcomes the harsh climate present on its planet. For example, if an animal lived on Mercury, it would need special protection to survive extreme hot and cold temperatures. 3. Explain how your organism exchanges elements with its atmosphere or soil, and how it moves around the planet. For instance, how does it “breathe” if there is no atmosphere? How would an organism move around a planet such as Jupiter, which does not have a solid surface? How would your organism deal with the extra gravity on a planet such as Neptune?

    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.
