Implementing District Standards
3.5 In third grade, the student will investigate and understand relationships among organisms in aquatic and terrestrial food chains. Key concepts include:
a) producer, consumer, decomposer
b) herbivore, carnivore, omnivore
c) predator and prey
In order to meet this standard, it is expected that students will:
- differentiate between predators and prey
- distinguish among producers, consumers, herbivores, omnivores, carnivores, and decomposers
- infer that most food chains begin with a green plant.
- identify sequences of feeding relationships in a food chain.
- explain how a change in one part of a food chain might affect the rest of the food chain.
- create and interpret a model of a food chain showing producers and consumers.
4.4 In fourth grade, the student will investigate and understand basic plant anatomy and life processes. Key concepts include:
a) the structures of typical plants and the function of each structure
c) photosynthesis
In order to meet this standard, it is expected that students will:
- analyze a common plant: identify the roots, stems, leaves, and flowers, and explain the function of each.
- explain the process of photosynthesis, using the following terminology: sunlight, chlorophyll, water, carbon dioxide, oxygen, and sugar.
5.3 In fifth grade, the student will investigate and understand basic characteristics of visible light and how it behaves. Key concepts include:
a) transverse waves
b) the visible spectrum
e) refraction of light through water and prisms
In order to meet this standard, it is expected that students will:
- diagram and label a representation of a light wave, including wavelength, crest, and trough.
- explain the relationships between wavelength and the color of light. Name the colors of the visible spectrum.
- analyze the effects of a prism on white light and describe why this occurs.
- explain the relationship between the refraction of light and the formation of a rainbow.
