Courses of Study: Credit Recovery Science


Credit Recovery Science, Grade 2, 2005

1.) Identify states of matter as solids, liquids, and gases.

•  Describing objects according to physical properties, including hardness, color, and flexibility
•  Describing changes between states of matter
Examples:

- solid to liquid—melting,

- gas to liquid—condensing,

- liquid to gas—evaporating,

- liquid to solid—freezing

•  Measuring quantities of solids and liquids
2.) Identify vibration as the source of sound.

•  Identifying pitch and volume as properties of sound
•  Distinguishing between pitch and volume of sound
3.) Recognize that light travels in a straight line until it strikes an object.

•  Recognizing that light can be reflected
4.) Describe observable effects of forces, including buoyancy, gravity, and magnetism.

Examples:

- buoyancy—boat floating on water,

- gravity—apple falling from tree,

- magnetism—magnets adhering to metal

•  Identifying simple machines, including the inclined plane, lever, pulley, wedge, screw, and wheel and axle
5.) Identify the relationship of structure to function in plants, including roots, stems, leaves, and flowers.

6.) Identify characteristics of animals, including behavior, size, and body covering

•  Comparing existing animals to extinct animals
Examples: iguana to stegosaurus, elephant to wooly mammoth

•  Identifying migration and hibernation as survival strategies
7.) Identify geological features as mountains, valleys, plains, deserts, lakes, rivers, and oceans.

•  Identifying local landforms and bodies of water
•  Identifying components of soil, including sand, clay, and silt
8.) Identify evidence of erosion and weathering of rocks.

9.) Describe evaporation, condensation, and precipitation in the water cycle.

10.) Identify the impact of weather on agriculture, recreation, the economy, and society.

•  Recognizing the importance of science and technology to weather predictions
11.) Identify basic components of our solar system, including the sun, planets, and Earth's moon.
