2009 Science NJCCCS:

5.3 Life Science: All studentswill understand that life science principles are powerful conceptualtools for making sense of the complexity, diversity, andinterconnectedness of life on Earth. Order in natural systems arises in accordance with rules that govern the physical world, and the order of natural systems can be modeled and predicted through the use of mathematics.

A. Organization and Development: Living organisms are composed of cellular units (structures) that carry out functions required for life. Cellular units are composed of molecules, which also carry out biological functions.

  • 5.3.P.A.1 Investigate and compare the basicphysical characteristics of plants, humans, and other animals.
  • 5.3.P.A.2 Observe similarities and differences inthe needs of various living things, and differences between living and nonliving things.
  • 5.3.2.A.1 Group living and nonliving things according to the characteristics that they share.
  • 5.3.4.A.1 Develop and use evidence-based criteria to determine if an unfamiliar object is living or nonliving.
  • 5.3.4.A.2  Compare and contrast structures that have similar functions invarious organisms, and explain how those functions may be carried out by structures that have different physical appearances.
B. Matter and EnergyTransformations: Food is required for energy and buildingcellular materials. Organisms in an ecosystem have different ways of obtaining food, and some organisms obtain their food directly from other organisms.

  • 5.3.P.B.1 Observe and describe how plants and animals obtain food from their environment, such as by observing the interactions between organisms in a natural habitat.
  • 5.3.2.B.1 Describe the requirements for the care of plants and animals related to meeting their energy needs.
  • 5.3.2.B.3 Explain that most plants get water from soil through their roots and gather light through their leaves.
  • 5.3.4.B.1 Identify sources of energy (food) in avariety of settings (farm, zoo, ocean, forest).
  • 5.3.6.B.1 Describe the sources of the reactants of photosynthesis and trace the pathway to the products.
  • 5.3.6.B.2 Illustrate the flow of energy (food) through a community.
