Core Content:
3.4.1 Students will explain the basic needs of organisms.
          (food, water, shelter, air)
         **Students will identify several organisms and their
         environmental needs and assign them to appropriate
3.4.2 Students will understand that things in the environment
        are classified as living, nonliving, and once living. Living  
        things differ from nonliving things.
        **Students will classify vertebrates into the categories by
            characteristics studied. Discuss how this helps them live
            in their environments.
3.4.3 Students will compare the basic structures and functions
         of plants and animals that contribute to growth,
         reproduction, and survival.
        **Describe plant and animal characteristics and make
            inferences about how they are adapted to their habitats.
       **Investigate animal structures that aid in its survival   
           (claws, poison, camouflage)
3.4.4 Students will compare a variety of plant and animal life  
         cycles to understand patterns of the growth, development,
         reproduction, and death of an organism.
       **Frog life cycle as part of pond study. Compare to other 
         life cycles. Sequence life cycle of the frog. (tree---forest)
4.6.1 Students will describe basic relationships of plants and
         animals in an ecosystem.
        **Food chain- ocean   Use terms predator, prey
        **Discuss photosynthesis and how the food chain begins
           with the sun and the plant making food.
4.7.1 Students will describe the cause and effect relationships
          existing between organisms and their environments.
         **Identify the characteristics of each ecosystem.
         **food chain, pictures of each environment
         **structures and functions of animals
