Life Science Standards Covered

All organisms need energy and matter to live and grow. As a basis for understanding this concept:

  • Students know plants are the primary source of matter and energy entering most food chains.
  • 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.
  • Students know decomposers, including many fungi, insects, and microorganisms, recycle matter from dead plants and animals.

Living organisms depend on one another and on their environment for survival. As a basis for understanding this concept:

  • Students know ecosystems can be characterized by their living and nonliving components.
  • 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.
  • Students know many plants depend on animals for pollination and seed dispersal, and animals depend on plants for food and shelter.
  • Students know that most microorganisms do not cause disease and that many are beneficial.

Scientific progress is made by asking meaningful questions and conducting careful investigations. As a basis for understanding this concept and addressing the content in the other three strands, students should develop their own questions and perform investigations. Students will:

  • Differentiate observation from inference (interpretation) and know scientists’ explanations come partly from what they observe and partly from how they interpret their observations.
  • Measure and estimate the weight, length, or volume of objects.
  • Formulate and justify predictions based on cause-and-effect relationships.
  • Conduct multiple trials to test a prediction and draw conclusions about the relationships between predictions and results.
  • Follow a set of written instructions for a scientific investigation.
