Contributing Teacher(s): Kenna McCleery

Subject Area: Science/Life

Grade Range: Lower Elementary (K-3)

Materials Needed:

Objective:

  1. Students will understand what food chains and food webs are and understand the differences between them.
  2. Students will understand the differences between predators and prey.

Essential Question:

    What is the difference between a food chain and a food web?

Instructional Strategy: Cooperative Learning

Process Standards:

  • Goal 1.6 discover and evaluate patterns and relationships in information, ideas and structures
  • Goal 1.4 use technological tools and other resources to locate, select and organize information

Content Standards:

  • Science 3. Characteristics and interactions of living organisms

    Time Allowance: 3/30 min class periods

    Technological Resources:

    1. Smart Board, ( if not possible, student computers will work)
    2. Internet capability
    3. sheppard software website

    Extensions:

    1. Have students share completed assessment posters with other groups.

    Integration:

    1. question and answer with peers

    Differentiation:

    1. one on one peer coaching
    2. partners or small groups

    Assessment:

    1. Work in pairs or small groups to create a foodweb poster.
    2. The web must include at least three correctly linked chains.
    3. Each organism will need to be labeled either predator, prey, or both.
    4. The poster needs to be neat and organized.
    5. Groups need to include their names and a title to the poster as well as work together cooperatively.

    Description: Students will gain understanding with the relationships between food chains and food webs. Students will be able to distinguish the roles of predator and prey.

    1. Begin lesson by reviewing Day 1 Lesson. Ask student pairs to tell each other what Day 1 vocabulary words are and give examples for each. (refer to Lesson 1)
    2. Connect SmartBoard or student computers to the website, www.sheppardsoftware.com.
    3. Go to the Herbivore, Carnivore, Omnivore link.
    4. Have students pair up and play the link "producer, consumer, decomposer game." This can be done whole class if a SmartBoard is used or in pairs or groups if student computers are used. Proceed to "animal diet game".
    5. Introduce lesson 2 by asking students if they know the difference between a food chain and a food web. Allow time for discussion. Have students write the following vocabulary words in their student journals: food web, food chain, predator and prey. Write these words on the chart paper or white board as well.
    6. Read aloud" What are Food Chains and Webs?" by Bobbie Kalman. Make sure to state that a FOOD CHAIN is the path that energy takes as one living thing eats another and a FOOD WEB is two or more food chains the overlap and link.
    7. Discuss that PREDATORS are animals that hunt other animals for food and PREY is the animals that are being hunted. Emphasize that sometimes as animal can be both predator and prey in a chain. Have students write the definitions in their science journals.
    8. Have students practice food chains by going back to the website, www.sheppardsoftwarecom.( "food chain game" link) Have students play whole class using the Smart board or in pairs or groups using student computers. Have students discuss which organisms are predator/prey in each chain.
    9. Begin assessment task by dividing students into pairs or groups. Hand out poster materials and instruct them to make a food web by linking together at least three chains. Students will need to label each organism as predator/prey/ or both. Students may use the magazines to find and clip out for poster, or draw and color their own organisms.
