I. Cells and Organisms
What is alive and what is not? What are the smallest units of life? How do plants store and use food? How can you classify organisms? These questions will be answered through investigation and manipulation of one-celled organisms; plants and the offspring, seeds; and photosynthesis and characateristics of vertebrates and invertebrates. A simple, clear analysis of reproduction and heredity concludes the course.
II. Interrelationships of Organisms - Ecosystems
This course will provide activities that explore a series of questions, whose answers tell us about the interrelationships of organisms. These questions are: How are parts of an ecosystem related and how do they interact? How is energy distributed to living things in an ecosystem? How do materials cycle through an ecosystem and get reused in the environment? How do communities of living things change over a period of time? How do humans interact with the environment? This last question leads to problems addressed in "environmental science," something that is of great interest to teachers and students alike.
