7.2: Physical Science

7.2.1: Matter The idea that matter is made up of atoms and molecules provides the basis for understanding the properties of matter. Recognize that all substances are composed of one or more of approximately one hundred elements and that the periodic table organizes the elements into groups with similar properties.

7.4: Life Science

7.4.1: Structure and Function in Living Systems Tissues, organs and organ systems are composed of cells and function to serve the needs of all cells for food, air and waste removal. Describe how the organs in the respiratory, circulatory, digestive, nervous, skin and urinary systems interact to serve the needs of vertebrate organisms.

Circulatory System
Digestive System All living organisms are composed of one or more cells which carry on the many functions needed to sustain life. Recognize that cells carry out life functions, and that these functions are carried out in a similar way in all organisms, including animals, plants, fungi, bacteria and protists.

Paramecium Homeostasis Recognize that cells repeatedly divide to make more cells for growth and repair.

Cell Division Use the presence of the cell wall and chloroplasts to distinguish between plant and animal cells.

Cell Structure

7.4.2: Interdependence among Living Systems Natural systems include a variety of organisms that interact with one another in several ways. Identify a variety of populations and communities in an ecosystem and describe the relationships among the populations and communities in a stable ecosystem.

Food Chain Compare and contrast predator/prey, parasite/host and producer/consumer/decomposer relationships.

Food Chain
Forest Ecosystem
Prairie Ecosystem Explain how the number of populations an ecosystem can support depends on the biotic resources available as well as abiotic factors such as amount of light and water, temperature range and soil composition.

Coral Reefs 1 - Abiotic Factors
Food Chain
Pond Ecosystem The flow of energy and the recycling of matter are essential to a stable ecosystem. Recognize that producers use the energy from sunlight to make sugars from carbon dioxide and water through a process called photosynthesis. This food can be used immediately, stored for later use, or used by other organisms.

Cell Energy Cycle
Food Chain
Forest Ecosystem
Photosynthesis Lab Describe the roles and relationships among producers, consumers and decomposers in changing energy from one form to another in a food web within an ecosystem.

Forest Ecosystem Explain that the total amount of matter in an ecosystem remains the same as it is transferred between organisms and their physical environment, even though its form and location change.

7.4.3: Evolution in Living Systems Reproduction is a characteristic of all organisms and is essential for the continuation of a species. Hereditary information is contained in genes which are inherited through asexual or sexual reproduction. Recognize that cells contain genes and that each gene carries a single unit of information that either alone, or with other genes, determines the inherited traits of an organism.

Mouse Genetics (One Trait) Distinguish between characteristics of organisms that are inherited and those acquired through environmental influences.

Mouse Genetics (One Trait)
Mouse Genetics (Two Traits) Individual organisms with certain traits in particular environments are more likely than others to survive and have offspring. Explain how the fossil record documents the appearance, diversification and extinction of many life forms.

Human Evolution - Skull Analysis Recognize that variation exists in every population and describe how a variation can help or hinder an organism?s ability to survive.

Natural Selection
Rainfall and Bird Beaks - Metric

7.4.4: Human Interactions with Living Systems Human activity can change living organisms and ecosystems. Describe ways that human activities can change the populations and communities in an ecosystem.

Coral Reefs 1 - Abiotic Factors
Coral Reefs 2 - Biotic Factors
Pond Ecosystem
Rabbit Population by Season Human beings are constantly interacting with other organisms that cause disease. Explain how viruses, bacteria, fungi and parasites may infect the human body and interfere with normal body functions.
