Assign groups and jobs within groups. Tell students that the schoolyard ecosystem is practice for gathering data and making observations of the ecosystems they will be exploring during their visits to Litzsinger's. (15 minutes) Students will make qualitative and quantitative observations in groups in their assigned area of the schoolyard ecosystem.

Identify ways in which ecosystems have changed throughout geologic time in response to physical conditions, interactions among organisms, and the actions of humans. Describe how changes may be catastrophes such as volcanic eruptions or ice storms. National Science Education Standards. Life Science: Populations and Ecosystems (pg.158-159)

Producers – organisms that produce their own food through photosynthesis. Consumers- organisms that must get energy from eating other organisms. Herbivores- consumers that eat only plants. Carnivores- organisms that eat only other animals. Omnivores- organisms that eat both plants and animals

1. Species – a group of organisms that can breed and produce fertile offspring. 2. Population – groups of individuals that are the same species and living in the same area. 3. Community – all of the living populations in an area. 4. Ecosystem - all the populations living together with the nonliving environment (living + nonliving components) 5.

Some are photosynthetic (vital for putting energy into ecosystems) Some are decomposers (vital for recycling matter in ecosystems) Some cause disease. One domain, Eukarya, consists of eukaryotes, organisms with a discrete cellular nucleus (and other internal membrane-bound organelles); it is divided into four kingdoms. Kingdom Protista - protists

In multicellular organisms, the body is a system of multiple, interacting subsystems. Subsystems are groups of cells that work together to form tissues. Organs are groups of tissues that work together to perform a particular body function. Tissues and organs are specialized for particular body functions. Systems may interact with other systems.
