The Structures of Life Module consists of four investigations dealing with observable characteristics of organisms. Students observe, compare, categorize, and care for a selection of organisms. In so doing, they learn to identify properties of plants and animals and to sort and group organisms on the basis of observable properties. Students investigate structures of the organisms and learn how some of the structures function in growth and survival. In this module, students will:
- Observe and compare properties of seeds and fruits.
- Investigate the effect of water on seeds by monitoring and recording changes over time.
- Observe plant structures as they appear during the plant's life cycle.
- Care for plants and animals and compare their needs.
- Observe crayfish structures and describe their functions in terms of growth, survival, and reproduction. Compare crayfish structures to structures of other animals.
- Use tables and graphs to organize and display data for analysis.
- Analyze and interpret observations of crayfish behavior.
- Investigate food chain dynamics through a simulation.
- Study skeletal systems using bones, images, and models.
