California Content Standards

Grade Three

Life Sciences

  • 3b. Students know examples of diverse life forms in different environments, such as oceans, deserts, tundra, forests, grasslands, and wetlands.
  • 3c. Students know living things cause changes in the environment in which they live: some of these changes are detrimental to the organism or other organisms, and some are beneficial.
  • 3d. Students know when the environment changes, some plants and animals survive and reproduce; others die or move to new locations.

Investigation and Experimentation

  • 5d. Predict the outcome of a simple investigation and compare the result with the prediction.
  • 5e. Collect data in an investigation and analyze those data to develop a logical conclusion.

Grade Four

Life Sciences

  • 2b. Students know producers and consumers (herbivores, carnivores, omnivores, and decomposers) are related in food chains and food webs and may compete with each other for resources in an ecosystem.
  • 3b. Students know that in any particular environment, some kinds of plants and animals survive well, some survive less well, and some cannot survive at all.

Investigation and Experimentation

  • 6f. Follow a set of written instructions for a scientific investigation.

Grade Five

Investigation and Experimentation

  • 6a. Classify objects (e.g., rocks, plants, leaves) in accordance with appropriate criteria.
  • 6g. Record data by using appropriate graphic representations (including charts, graphs, and labeled diagrams) and make inferences based on those data.

Grade Eight

Investigation and Experimentation

  • 9d. Construct appropriate graphs from data and develop quantitative statements about the relationships between variables.
