Use models to describe that energy in animals’ food (used for body repair, growth, motion, and to maintain body warmth) was once energy from the sun.

Support an argument that plants get the materials they need for growth chiefly from air and water.

Develop a model to describe the movement of matter among plants, animals, decomposers, and the environment.

Conduct an investigation to provide evidence that living things are made of cells; either one cell or many different numbers and types of cells.

Develop and use a model to describe the function of a cell as a whole and ways parts of cells contribute to the function.

Use argument supported by evidence for how the body is a system of interacting subsystems composed of groups of cells.

Use argument based on empirical evidence and scientific reasoning to support an explanation for how characteristic animal behaviors and specialized plant structures affect the probability of successful reproduction of animals and plants respectively.

Construct a scientific explanation based on evidence for how environmental and genetic factors influence the growth of organisms.

Construct a scientific explanation based on evidence for the role of photosynthesis in the cycling of matter and flow of energy into and out of organisms.

Develop a model to describe how food is rearranged through chemical reactions forming new molecules that support growth and/or release energy as this matter moves through an organism.
