Food Webs : A Technology Infused Lesson Developed by Christine Dennis
Grade Level: Intermediate (gr. 3-5)
Subject Area: Science (ecology)
Physical Classroom Setup:
Day 1 can be taught in any regular classroom that contains a SMARTboard
Days 2 & 3 can best be taught in a lab setting or using laptops (i.e., COWs)
Research food webs using the internet and participate in a teacher-created wiki
Create a model of a food web using Inspiration software
SMARTboard & PowerPoint presentation (teacher)
Teacher-created wiki (students & teacher)
Desktop computers (students)
Inspiration software (students)
Purpose & Task
Display an understanding of the interdependence between the food chains within a food web.
The students must use research food webs online and participate in a wiki. Then, they must work with their partner/group using Inspiration to illustrate a food web, based on web-based research.
Students have been learning about food chains and food webs
Teacher has already introduced and explained the class wiki
Students are comfortable accessing and participating in the class wiki
Procedure (Day 1)
Begin with a higher-order thinking question: (HOTS- Analysis) “Can you identify the different parts of a food web? First think of a food chain and then think about what a food web is.” (A series of interconnected food chains)
Show students slide containing “A food web contains…”
Talk about some of the living things in an Antarctic food web. Ask students to brainstorm some of the animals they think they may find in that habitat.
Show slide with list of living things to be used in the food web. Make sure to explain that we are only using some of the organisms but there are many more.
Ask students to identify any producers, consumers, decomposers, etc. that they see on the slide. (When identifying consumers, make sure students tell if they are carnivores, herbivores, or omnivores.)
Show slide with each chain color coded so students better see the connections between each group of organisms.
“ Do our food chains start with a producer? Do any end with a decomposer? What is an example of a decomposer we might find in a watery habitat?”
Ask for student volunteers to become the different organisms within the food web. Give each one a picture card to wear around their neck (this will identify who they are in the food web).
Using the slide on the Smart Board as a guide, begin to connect the food chains. (Since some of the organisms appear so frequently, there may be more than one student playing that organism).
As the chains are being connected in different colored yarn across the room, ask students to look for the most common links. “Who is at the beginning and ends of all the food chains?”
Begin asking questions about who would be affected if certain populations suddenly increased or decreased.
After all chains have been connected and the web is complete, have the krill let go of their yarn. Ask the class to observe what happened to the web.
(HOTS- Synthesis) “Which food chains are affected by the loss of the krill? How many organisms are affected positively by the loss of the krill? How many are affected negatively?”
End with class discussion on the important things they learned about a food web. Encourage feedback on something they learned or observed during the lesson.
Procedure (Day 2)
Students will be split into pairs or groups (depending on numbers and classroom dynamics)
Each group will be given a specific food web to research
Students will use the internet to find out the members of their food web and classify them according to member (i.e., producer, consumer, decomposer, etc.)
Students will then record their findings in the their web’s designated section of the class wiki
Students must communicate with their partner/group throughout the research and wiki process as to not overlap/overwrite what the other members are contributing
Procedure (Day 3 - if needed)
Each group will be asked to use Inspiration software to illustrate the food web the researched.
Students will be shown an example based on the Antarctic food web used in class
The teacher will then model how to begin building the food web using pictures and the various tools within Inspiration
The students would be evaluated based on the rubric provided to them at the start of the lesson.
Students must fill out a “Group Participation” rubric as well that would be turned in with their final product.
