Standard Area - MST:
  • Standard - MST4: Students will understand and apply scientific concepts, principles, and theories pertaining to the physical setting and living environment and recognize the historical development of ideas in science.
  • Key Idea Code - MST4.LE:
  • Key Idea - MST4.LE3: Individual organisms and species change over time.
  • Academic Level - MST4.E.LE3:
  • Performance Indicator - MST4.E.LE3A: Students describe how the structures of plants and animals complement the environment of the plant or animal.
  • Major Understandings - 3.1a : Each animal has different structures that serve different functions in growth, survival, and reproduction.
    • wings, legs, or fins enable some animals to seek shelter and escape predators
    • the mouth, including teeth, jaws, and tongue, enables some animals to eat and drink
    • eyes, nose, ears, tongue, and skin of some animals enable the animals to sense their surroundings
    • claws, shells, spines, feathers, fur, scales, and color of body covering enable some animals to protect themselves from predators and other environmental conditions, or enable them to obtain food
    • some animals have parts that are used to produce sounds and smells to help the animal meet its needs
    • the characteristics of some animals change as seasonal conditions change (e.g., fur grows and is shed to help regulate body heat; body fat is a form of stored energy and it changes as the seasons change)
  • Major Understandings - 3.1b : Each plant has different structures that serve different functions in growth, survival, and reproduction.
    • roots help support the plant and take in water and nutrients
    • leaves help plants utilize sunlight to make food for the plant
    • stems, stalks, trunks, and other similar structures provide support for the plant
    • some plants have flowers
    • flowers are reproductive structures of plants that produce fruit which contains seeds
    • seeds contain stored food that aids in germination and the growth of young plants
  • Major Understandings - 3.1c : In order to survive in their environment, plants and animals must be adapted to that environment.
    • seeds disperse by a plant’s own mechanism and/or in a variety of ways that can include wind, water, and animals
    • leaf, flower, stem, and root adaptations may include variations in size, shape, thickness, color, smell, and texture
    • animal adaptations include coloration for warning or attraction, camouflage, defense mechanisms, movement, hibernation, and migration
