Plan a Testable Storm Shelter

Engineering — Disaster-Resistant Design | Unit 1, Lesson 3 of 6

📚 Grade: 4th Grade⏱️ Duration: 45–60 minutes🛠️ Subject: Engineering — Disaster-Resistant Design

✏️🏗️📋

A strong plan makes later testing clearer and fairer.

📋 NGSS Standard:
3-5-ETS1-1 / 3-5-ETS1-2 / 3-5-ETS1-3 — Define a design problem with criteria and constraints, generate and compare solutions, and plan fair tests with variables controlled and failure points considered.

🎯 Learning Objective

Students will draw and label a storm shelter plan that includes materials, structure, and a testable prediction.

💡 The Big Idea

Planning helps engineers think ahead about structure, materials, and evidence.

🔬 Engineering Thinking

Science Snapshot

Testable plans connect each design feature to a specific job in the system.

What is happening?

A shelter plan should show the layout, the materials, and how the design is supposed to solve the storm problem. A plan is testable only when the design choices are specific enough to build and compare.

Why it works that way

Students also need to control variables. If shape, materials, and test conditions all change at once, they cannot tell which feature caused the better result.

Look for this in the lesson

Students should label each part with a reason: “This roof slope helps rain run off,” or “This base helps the shelter stay balanced.” That turns a sketch into an engineering explanation.

Ask while you read: What design feature in your plan is most important to test first?

Materials

Printed lesson pages and worksheet
Pencil and ruler
Reference notes from lessons 1 and 2

Let's Get Started

Step 1 — Review the design brief
Revisit the shelter problem, criteria, and constraints.

Step 2 — Sketch the design
Draw the shelter from at least one view and label key parts.

Step 3 — Add material choices
Name what each part is made from.

Step 4 — Predict performance
Students write what they think the shelter will do in wind and rain tests.

Step 5 — Check plan quality
Confirm the plan is clear enough for someone else to follow.

Discussion Questions

Why is labeling important in engineering planning?Labels make the design easier to build and test.

What should a prediction include?What the design will do and why.

How does a plan connect to fair testing?Clear plans make it easier to compare results honestly.

Why should the plan match the constraints?A design that ignores limits is not realistic.

Extensions

Extension: Have a family member read the plan and tell you what is clear or confusing.

Parent/Teacher Notes

Teaching note: Students should not only draw a shelter; they should annotate it with function and material choices.

Misconception to catch: A pretty drawing is not enough if it lacks testable details.

Sample ideas

Strong plans identify walls, roof, supports, and materials, plus a prediction such as “The slanted roof will help rain run off instead of pooling.”

✅ What Success Looks Like

Student creates a labeled plan.
Student includes materials and a testable prediction.
Student connects the plan to criteria and constraints.
