Science Worksheets and Study Guides Third Grade. What are Ecosystems?

The resources above correspond to the standards listed below:

New Hampshire Standards

NH.LS1. Life Science: All living organisms have identifiable structures and characteristics that allow for survival (organisms, populations, and species).
S:LS1:4:3.2. Reproduction: Students will recognize that living organisms have life cycles, which include birth, growth and development, reproduction, and death; and explain how these life cycles vary for different organisms.
S:LS1:4:3.4. Reproduction: Students will predict, sequence, or compare the life stages of organisms (plants and animals): e.g., put images of life stages of an organism in order, predict the next stage in sequence, and compare two organisms.
NH.LS2. Life Science: Energy flows and matter recycles through an ecosystem.
S:LS2:4:2.1. Flow of Energy: Students will recognize that the transfer of energy through food is necessary for all living organisms and describe the organization of food webs.
S:LS2:4:2.2. Flow of Energy: Students will recognize that energy is needed for all organisms to stay alive and grow or identify where a plant or animal gets its energy.
S:LS2:4:3.2. Recycling of Materials: Students will describe ways plants and animals depend on each other (e.g., shelter, nesting, food).
NH.SPS2. Science Process Skills: Unifying Concepts of Science
S:SPS2:4:4.3. Patterns of Change: Students will apply skills from previous grades and demonstrate that some features of things may stay the same even when other features change (e.g., some patterns look the same when they are shifted over, turned, reflected, or seen from different directions).
