During this unit, students describe characteristics of various organisms (i.e. color, size and shape). Students compare and sort organisms based on their characteristics. Students observe and record the changes of an organism through its life cycle. Students identify the basic needs of both plants and animals.
According to Research
Emphasis should be placed on examining a variety of familiar animals and plants and considering things and processes they all need to stay alive, such as food and getting rid of wastes. Students should investigate the habitats of a variety of local plants and animals, including weeds, aquatic plants, insects, worms, and amphibians, and some of the ways in which animals depend on plants and on each other.
