5E lesson flow

  1. 01

    Engage

    6 min

    Teacher Does

    Show dark-bark insects.

    Students Do

    Notice variation.

    Ask

    • What varies?

    Look For

    Color variation.

  2. 02

    Explore

    11 min

    Teacher Does

    Reveal three trials.

    Students Do

    Compare and total data.

    Ask

    • What repeats?

    Look For

    7 versus 21.

  3. 03

    Explain

    8 min

    Teacher Does

    Model calibrated claims.

    Students Do

    Build variation-effect-advantage chains.

    Ask

    • What is supported?

    Look For

    Advantage, not guarantee.

  4. 04

    Elaborate

    12 min

    Teacher Does

    Open Dry Meadow cards.

    Students Do

    Rank habitat fit with evidence.

    Ask

    • Which needs are met?

    Look For

    Two evidence matches.

  5. 05

    Evaluate

    8 min

    Teacher Does

    Prompt final argument.

    Students Do

    Integrate evidence and limitation.

    Ask

    • What can you not conclude?

    Look For

    Habitat-specific limit.

Student goal

I can use repeated data and habitat evidence to build a survival argument.

Learning objectives

  • Use repeated evidence to explain how a variation in a characteristic can provide an advantage in a particular habitat.
  • Use organism needs and habitat characteristics to compare which organisms can survive well, less well, or not at all in a specific habitat.
  • Construct an evidence-based argument without claiming that an advantage guarantees survival or that organisms choose inherited traits because they need them.

Materials

  • Camouflage trial data
  • Dry Meadow profile
  • Organism cards

Before class

  • Use equal viewing trials.
  • Avoid purposeful-trait and guarantee language.

Prior knowledge

  • Organisms have needs.
  • Individuals can vary.

Vocabulary

habitat
The place where an organism lives and gets what it needs.
characteristic
A feature of an organism.
variation
A difference in a characteristic among individuals of the same kind.
advantage
A characteristic that can improve an organism's chance in a particular habitat.
survive
To stay alive and meet basic needs.
evidence
Observations or data used to support an explanation.

Differentiation

  • Use picture-supported cards.
  • Offer a habitat-feature sentence frame.

Assessment

  • Check repeated data use.
  • Check ranking evidence.
  • Reject guarantee and choice claims.

Exit ticket

Name one habitat-specific advantage and its evidence.

Extension

Compare the same variation in another habitat.
