Students love this 45-minute card sort and assessment! This NGSS lesson on MS-LS2-2 standard lesson is engaging, collaborative, challenging and perfect for middle school or high school food webs and food chains.

What students do:

In this lesson, students attempt to sort American Prairie ecosystem animal cards into a food chain, once they correctly sort them, they fill in a handout.

Students then attempt to rearrange the cards into a food web.

Students then read passages about food webs and food chains to enhance their learning experience. Using their new knowledge from the reading, students rearrange the cards correctly.

Students will then draw the food web on a handout and label various organisms such as Carnivores, Herbivores, Omnivores, Primary Producers, Primary Consumers, Secondary Consumers, Tertiary Consumers, and Decomposers.

Finally, to assess their understanding, students will take a Google Form assessment.

This resource includes the following:

To make your job easy, an 11 Slide Teacher slideshow for student instructions, student expectations, and lesson pacing.

Includes the Following NGSS Standards:

LS2.C:  Ecosystem Dynamics, Functioning, and Resilience

• Ecosystems are dynamic in nature; their characteristics can vary over time. Disruptions to any physical or biological component of an ecosystem can lead to shifts in all its populations. (MS-LS2-4)

LS2.A:  Interdependent Relationships in Ecosystems

• Organisms, and populations of organisms, are dependent on their environmental interactions both with other living things and with nonliving factors. (MS-LS2-1)

• In any ecosystem, organisms and populations with similar requirements for food, water, oxygen, or other resources may compete with each other for limited resources, access to which consequently constrains their growth and reproduction. (MS-LS2-1)

Crosscutting Concepts

Cause and Effect: Cause and effect relationships may be used to predict phenomena in natural or designed systems.

Systems and System Models: Models can be used to represent systems and their interactions—such as inputs, processes and outputs—and energy, and matter flows within systems.

Patterns: Observed patterns in nature guide organization and classification and prompt questions about relationships and causes underlying them.

Energy and Matter: Tracking energy and matter flows, into, out of, and within systems helps one understand their system’s behavior.

Stability and Change: For both designed and natural systems, conditions that affect stability and factors that control rates of change are critical elements to consider and understand.
