Introduction
Bob has just bought land in the middle of the desert. The sun blazes during the day, the nights turn surprisingly cold, and sandstorms sometimes sweep through without warning. Bob dreams of a house that can keep him cool in the heat, warm in the cold, and safe from the desert winds.
That’s where you come in. Bob has hired you as his architect, and he’s counting on your expertise. Your quest: investigate different construction materials and decide which ones can survive—and even thrive—in the desert. Along the way, you’ll weigh comfort, durability, cost, and sustainability to design Bob’s perfect desert home.
Task
Your mission is to become Bob’s architectural team and propose the best construction materials for his desert home.
To succeed, you will:
- Research at least five possible building materials (for example: adobe, stone, concrete, steel, glass).
- Compare their advantages and disadvantages in hot, dry climates — considering comfort, durability, cost, and sustainability.
- Decide which materials (or combination of materials) are best for Bob’s house.
- Present your proposal in a clear and creative format: a short report, poster, or slideshow that includes text, images, and your final recommendation.
Bob is counting on you to make his dream house a reality — choose wisely!
Process
No great architect works alone!
Every great project begins with a team. Work in groups of 4 and assign roles:
- The Researcher digs into sources and gathers facts.
- The Designer sketches or imagines how the house will look.
- The Writer crafts the proposal in words.
- The Presenter delivers the final pitch to Bob.
If you’re solo, congratulations — you get to play all four roles!
Step into the desert.
Picture Bob’s empty plot of land: endless sand, burning sun by day, freezing winds at night. Your first mission is to study the available building materials. Search for at least five (such as adobe, stone, concrete, steel, and glass) and find out:
- How well does it protect from heat and cold?
- How durable is it against sand, wind, and sun?
- How expensive is it to build with?
- How sustainable is it for the environment?

Weigh your options.
Architects don’t choose blindly. Create a comparison chart of the materials. List the strengths and weaknesses of each one. This is your “battle plan” for deciding which materials can survive the desert and which cannot.
Make the call.
Now imagine Bob sitting across the table, waiting. Which material will you recommend? Will it be the natural cooling of adobe, the strength of concrete, the sleekness of steel, or a clever combination? Choose wisely — your decision will shape Bob’s future home.
Bring the vision to life.
Prepare a final proposal. This can be a slideshow, poster, or written report. It must include:
- At least 5 well-chosen images.
- Your material comparison chart.
- A clear explanation of why you made your choice.
Present your masterpiece.
At last, you’ll face Bob (and the class). Share your proposal as if you’re pitching to a real client. Be persuasive, professional, and creative — Bob needs to be convinced that your design will stand strong in the desert.

Good (3–4 pts) |
Needs Work (1–2 pts) |
Missing (0 pts) |
|

No real research provided. |
|
Comparison & Justification |
Clear, well-organized chart; strong reasoning for chosen material(s). |
Some comparison provided; reasoning somewhat clear. |
Weak or incomplete comparison; little justification. |
No comparison or reasoning shown. |
|
Creativity & Presentation |
Final proposal is engaging, neat, visually appealing, and convincing to Bob. |
Proposal is clear but could use more creativity or organization. |
Proposal is confusing or sloppy; lacks persuasion. |
No final product presented. |
|
Use of Images |
At least 5 well-sized images that strongly support the proposal. |
3–4 images, somewhat relevant or inconsistent sizing. |
Fewer than 3 images, or poorly formatted. |
No images included. |
|
Teamwork/Role Play |
Roles well defined, collaboration obvious (or solo student covers all roles with excellence). |
Roles mostly clear; some collaboration. |
Minimal teamwork; uneven participation. |
No evidence of teamwork. |
Total: 25 points (scaled to 5 rubric points)
Conclusion
Your journey as Bob’s architect is complete. Along the way, you discovered that building in the desert isn’t just about style — it’s about choosing the right materials to battle the sun, the sand, and the cold nights.
By comparing and selecting the best options, you’ve learned how architects weigh comfort, durability, cost, and sustainability to bring a vision to life.
Bob now has a house that can stand strong in the desert — thanks to you. And as you move on from this quest, remember: every building tells a story, and the materials are its language.

Title: Building Bob’s Desert House: Choosing the Right Materials
Grade Level: High School (Grades 10–12) or Undergraduate Architecture Students
Subject Area: Architecture / Environmental Design / Sustainability
Overview
This WebQuest places students in the role of architects tasked with designing a house for a client, Bob, who has purchased land in the desert. The activity emphasizes inquiry-based learning by having students research, compare, and justify construction material choices based on climate, durability, sustainability, and cost.
Objectives
By completing this WebQuest, students will be able to:
- Identify and describe at least five building materials relevant to hot, arid climates.
- Analyze the strengths and weaknesses of each material in terms of thermal performance, durability, cost, and sustainability.
- Synthesize research into a comparison table and final proposal.
- Develop skills in teamwork, role distribution, and persuasive presentation.
- Apply architectural thinking to a real-world design challenge.
Standards Alignment
(example placeholders; adjust to your curriculum)
- Critical thinking and problem solving (21st Century Skills).
- Research and information literacy.
- Environmental design and sustainability standards.
- Communication and collaboration skills.
Implementation Notes
- Time Required: 3–5 class sessions (research, comparison, proposal creation, presentation).
- Group Size: 3–4 students per group recommended (though the quest can be done individually).
- Materials Needed: Internet access, presentation software (PowerPoint/Google Slides), poster supplies (if offline), and access to research resources.
- Assessment: Students are evaluated using the provided rubric (see Evaluation section).
Teacher Tips
- Encourage students to think beyond traditional building materials and consider vernacular solutions (e.g., adobe, wind towers, yakhchāl).
- Guide them toward balancing creativity with feasibility.
- Remind them that images should be credited and resized appropriately.
- Consider allowing creative presentations (sketches, mock-ups, models) if time permits.
