Challenges for Elementary School Students (CHESS)Des Moines Session 3 - July 21-July 25 AND July 28-August 1, 2008Science Investigations: Freshwater Ecology: A Universe in a Drop of Water (Grades 4 - 6) 9 am-12 pmEast High School, in Room 3009C Together we will explore the amazing world of biology as applied to a fresh water ecosystem (a pond ecosystem). Ever seen a paramecium… or an amoeba? Figured out the species of a frog? Ever collected specimens for study? This course will show you the fun and exciting world of the limnologist (also known as a fresh water ecologist). Your adventure will begin with the domains and kingdoms of life on Earth and the general field of biology. Then to the pond where we will begin to understand how its unique populations of organisms work together as a community. Our tools will be microscopes, nets, and the camera among others. We will explore this world in the lab and in the field. By the end of the two weeks you will be a budding limnologist! Instructor
