_________________________________________________________________________ The Characteristics of Life: Observing Life at the Macroscopic Level __________________________________________________________________________ ____ Introduction/Rationale Observation is an important part of the scientific method. In this laboratory exercise you will be observing living organisms at the macroscopic level. You will be recording your observations with a digital camera and by making sketches with the aid of the greatest macroscope ever designed - the vertebrate eye. Recording your macroscopic observations will help you study the living organism you are observing and enhance the learning experience. After recording your observations a series of questions will be presented to help you communicate what you learned about the biology of living organisms. Learning Objectives The specific objectives of this laboratory are to have the student: 1. observe and study living organisms. 2. think about what characteristics are unique to living organisms. 3. use the metric system to make measurements. 4. learn how to use a digital camera and capture and send digital pictures. Method You will be locating TWO different living organisms, preferably in their natural habitat. The two organisms you choose should be somewhat dissimilar to each other. For example, if one you choose is a plant, then perhaps the other one is an animal. You will make a sketch of one of the organisms and take a digital photograph of the other. You will insert the sketch and photograph into the appropriate places in the lab document and provide some information about each organism. Then you will complete the questions/problem solving items at the end of the lab document. Here are a few guidelines and rules that will help you with the selection of the organism. Each organism must be a macroscopic (easily seen with the human eye). Your sketch and photo must be of organisms that you actually observed. The organism can be found inside buildings but it is preferable that you locate them in their natural habitat. (an aquarium is an acceptable viewing location) When photographing or drawing large plants (like a tree or shrub), you may draw or photograph only a portion of the plant as representative of the entire plant. Leaves and flowers are particularly important for identifying a plant.

    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.
