Grade 5
STEM Learning Garden Unit: Food Web
5-LS2 Ecosystems: Interactions, Energy, and Dynamics
Massachusetts State Standards:
5-LS2-1. Develop a model of a food web to describe the movement of matter among producers, primary and secondary consumers,
decomposers, and the air and soil in the environment: a. show that plants produce sugars and plant materials; b. show that some
animals eat plants for food and other animals eat the animals that eat plants; and c. show that some organisms, including fungi and
bacteria, break down dead organisms and recycle some materials back to the air and soil. [Clarification Statement: Emphasis is on
matter moving throughout the ecosystem. Waste includes matter in the form of gasses (such as air), liquids (such as water), or
solids (such as minerals or nutrients).] [Assessment Boundary: Assessment does not include molecular explanations.]
Essential Questions: How are animals and plants dependent on one another?
Perfromance Expectation: (What will the students know and be able to do after this unit? Matching the student task or question
directly with the practices.) Students will be able to make a model to illustrate a food web. Using the food web model,
students will be able to evaluate the habitat where changes occur due to natural and man made effects.
Science and Engineering Practices
Developing and Using Models Develop a model to describe
phenomena.
Engaging in Argument from Evidence Support an argument
with evidence, data, or a model.
Analyzing and Interpreting Data Analyze and interpret data to
determine similarities and differences in findings
Standards for Mathematical Practices
Make sense of problems and persevere in solving them.
Reason abstractly and quantitatively.
Construct viable arguments and critique the reasoning of
others.
Model with mathematics.
Use appropriate tools strategically.
Attend to precision.
Look for and make use of structure.
Look for an express regularity in repeated reasoning.
Disciplinary Core Ideas
LS2.A: Interdependent Relationships in
Ecosystems
Organisms are related in food webs in which some
animals eat plants for food and other animals eat the
animals that eat plants.
Some organisms, such as fungi and bacteria, break
down dead organisms (both plants or plants parts
and animals) and therefore operate as
decomposers. Decomposition eventually restores
(recycles) some materials back to the soil.
LS2.B: Cycles of Matter and Energy Transfer in
Ecosystems
Matter cycles between the air and soil and among
plants, animals, and microbes as these organisms
live and die. Organisms obtain gases, and water,
from the environment, and release waste matter
(gas, liquid, or solid) back into the environment.

ELA Standards
SL. 1. Engage effectively in a range of collaborative
discussions (one-on-one, in groups, and teacher-led) with
diverse partners on grade 5 topics and texts, building on
others ideas and expressing their own clearly.
W.1. Write opinion pieces on topics or texts, supporting a
point of view with reasons and information.
W. 2. Write informative/explanatory texts to examine a
topic and convey ideas and information clearly.
