Life Science: The students will use scientific skills and processes to explain the dynamic nature of living things, their interactions, and the results from the interactions that occur over time.
Diversity of Life: Compile evidence to verify the claim of biologists that the features of organisms connect or differentiate them-these include external and internal structures (features) and processes.
Provide examples and explain that organisms sorted into groups share similarities in external structures as well as similarities in internal anatomical structures and processes which can be used to infer the degree of relatedness among organisms: Vascular - non vascular plants; Closed - open circulatory systems; Asexual - sexual reproduction; Respiration (lungs-gills-skin); Digestion.
Use analogies, models, or drawings to represent that animals and plants have a great variety of body plans and internal structures that define the way they live, grow, survive, and reproduce.
Cells: Gather and organize data to defend or argue the proposition that all living things are cellular (composed of cells) and that cells carry out the basic life functions.
Use microscopes or other magnifying instruments to observe, describe, and compare the cellular composition of different body tissues and organs in a variety of organisms (animals and plants).
Based on data from readings and designed investigations, cite evidence to illustrate that the life functions of multicellular organisms (plant and animal) are carried out within complex systems of different tissues, organs and cells: Extracting energy from food; Getting rid of wastes; Making raw materials.
Flow of Matter and Energy: Explain that the transfer and transformation of matter and energy links organisms to one another and to their physical setting.
Investigate and describe the processes that enable plants to use the energy from light to make sugars (food) from carbon dioxide and water.
