3: Physical Science
3.1: Explain that all matter is composed of atoms and describe the basic composition and characteristics of an atom. Explain that all forms of matter are composed of one or more of approximately 100 elements and give examples of specific elements.
3.2: Compare and contrast the two different types of mechanical energy: potential and kinetic. Identify the three common forms of potential energy: gravitational, chemical and elastic.
Inclined Plane - Sliding Objects
Potential Energy on Shelves
4: Earth and Space Science
4.1: Explain how the sun's gravitational pull keeps objects in our solar system in regular and predictable motion. Use models to demonstrate how earth's gravity pulls all objects near earth toward the center of the earth. Create models of the major bodies in our solar system, showing their relative sizes and their relative distances from the sun.
4.2: Describe with models or drawings how the earth's tilt on its axis relative to the plane of the earth's yearly orbit around the sun is responsible for seasonal weather changes. Explain how global patterns of air movement are caused by differential heating of air, land and oceans, and how these patterns affect weather and climate patterns.
Seasons in 3D
Seasons: Why do we have them?
Summer and Winter
5: Life Science
5.1: Describe specific interactions between organisms and categorize the effects on the organisms as beneficial, harmful, neither or both. Explain how dead plants and animals are broken down by scavengers and decomposers and how this process contributes to the system as a whole.
5.2: Describe how energy from the sun is transformed by plants into sugar and transferred within a food chain from producers to consumers and decomposers. Trace the one-way path energy takes through producers, consumers and decomposers. Compare and contrast organisms at each level of a food chain with regard to how they obtain and use energy. Describe the criteria by which organisms are classified and how their identifying characteristics are related to their role in the food chain.
