5E lesson flow

  1. 01

    Engage

    6 min

    Teacher Does

    Present several earthquake impacts.

    Students Do

    Choose one focal impact.

    Ask

    • Which impact are we reducing?

    Look For

    Specific impact.

  2. 02

    Explore

    14 min

    Teacher Does

    State the criterion and constraint; run three designs five times each.

    Students Do

    Record performance and cost.

    Ask

    • Was every test comparable?

    Look For

    All three results.

  3. 03

    Explain

    9 min

    Teacher Does

    Clarify criterion, constraint, evidence, and tradeoff.

    Students Do

    Label the design brief.

    Ask

    • Which is success and which is a limit?

    Look For

    Correct distinction.

  4. 04

    Elaborate

    13 min

    Teacher Does

    Present monitoring, warning, and evacuation options.

    Students Do

    Match solutions to impacts and consider a combination.

    Ask

    • Could two solutions work together?

    Look For

    Different targeted impacts.

  5. 05

    Evaluate

    8 min

    Teacher Does

    Request a recommendation and limit.

    Students Do

    Cite two details and explain a tradeoff.

    Ask

    • What does evidence not show?

    Look For

    No overclaim.

Student goal

I can compare hazard-impact solutions and recommend a fit using evidence.

Learning objectives

  • Identify a specific impact caused by an earthquake, flood, tsunami, or volcanic eruption that people may try to reduce.
  • Generate or compare multiple solutions using stated criteria, constraints, and test or scenario evidence.
  • Recommend a solution or combination of solutions while explaining a tradeoff and keeping the claim within what the evidence supports.

Materials

  • Lightweight model-building materials
  • Gentle shake-test tray
  • Cost cards
  • Volcano scenario cards
  • Data sheet

Before class

  • Prepare three neutral designs.
  • Use a repeatable gentle test.
  • Avoid frightening simulations.
  • Open Teach Mode.

Prior knowledge

  • Earth processes can affect people and places.
  • Students can read a result table.

Vocabulary

hazard
A natural process or event that can cause harm.
impact
An effect on people, structures, or places.
solution
A design or plan intended to reduce a problem.
criterion
Something a successful solution must do.
constraint
A limit such as cost, time, or materials.
evidence
Information used to support a decision.
tradeoff
What is gained and given up with a choice.

Differentiation

  • Use icons for performance and cost.
  • Provide a recommendation frame.
  • Allow oral rehearsal.
  • Extension: revise within the constraint.

Assessment

  • Check all three designs were compared.
  • Require two evidence fields.
  • Check tradeoff and claim limit.

Exit ticket

Recommend a solution using one result and one constraint.

Extension

Combine warning and evacuation solutions for a volcano scenario.
