Week 13: Fix-It Detective (Designing for Disassembly and Reuse)

Unit 4: Better System Shapes

This Week's Big Question

What clues tell you whether an object was designed to be fixed?

This week children become repair detectives. They compare objects that invite fixing with objects that seem sealed shut, then ask what design choices make repair easier or harder.

Kid Version in One Sentence

An object is easier to keep in use when it is designed to be opened, fixed, and reused.

You'll Discover

• which clues make an object seem repair-friendly
• why replaceable parts and clear access matter
• how repair can reduce how much new material has to move through a system

Grown-up Note

• Use safe, non-powered objects when possible.
• Keep policy details out of the main path; this week is about design clues, not legal debate.
• Sessions are designed for about 20 minutes. Use the Short Path when you only have 15-20 minutes. Extra Challenge options can stretch closer to 25-30 minutes.
• Policy details, current laws, and company claims work best as guided or extension-level material for ages 11-13.

Common Kid Misconceptions

• Misconception: "New is always better." Response: "Sometimes repair is the better systems choice because it uses less new material."
• Misconception: "If an object is sealed, that means it is higher quality." Response: "Sometimes it only means it is harder to open or replace parts."
• Misconception: "Only experts can repair anything." Response: "Some repairs are simple. Some need experts. Design affects which is which."

Week at a Glance

Session length	About 20 minutes
Prep time	About 10 minutes
Materials	Two safe objects to compare, paper, pencil, screwdriver only if needed for a safe non-powered object, Systems Log
Safety	Do not open mains-powered devices, lithium battery products, swollen batteries, or unknown electronics
Core vocabulary	repair, screw, glue, part, clue
Older learner words	designed for replacement, designed obsolescence, Right to Repair, throughput

Core Vocabulary

Word	Kid-friendly meaning
repair	To fix something so it works again
screw	A fastener that can usually be removed and replaced
glue	A sticky join that can make repair harder
part	One piece of a larger object
clue	A sign that helps you figure something out

Short Path for Younger Learners

• Compare one easier-to-fix object with one harder-to-fix object.
• Look for simple clues: screws or glue, replaceable battery or sealed case.
• Draw a repair-friendly object and label removable parts.
• End with a Systems Log entry.

Success looks like: the child can name at least two clues that make repair easier or harder.

Extra Challenge for Older Learners

• Compare standard parts, hidden fasteners, and available instructions.
• Explain how easier repair can reduce how much new material flows through a system.
• Discuss why some companies design for quick replacement instead of repair.

Read-Aloud Opening

"Today we are looking for repair clues. Some objects seem to say, 'You can open me and fix me.' Others seem to say, 'Replace me when I break.' We are going to figure out which design choices send those messages."

Guided Session 1: Compare Two Objects

Time: 20-25 minutes

Materials: two safe objects, paper, pencil

Safety note: Stay away from risky electronics and damaged batteries.

Setup: Put two safe objects side by side, such as a toy with screws and a sealed item, or a flashlight with replaceable batteries and a sealed device.

Activity steps:

1. Look at both objects slowly.
2. List the visible clues.
3. Sort the clues into helpful for repair or harder for repair.
4. Decide which object seems more repair-friendly.

What to ask:

• Which object looks easier to open?
• Which one has parts you could replace?
• What clue matters most to you?

Draw It: Draw the more repair-friendly object and label its removable parts.

Talk About It:

• Why are screws often friendlier than glue?
• Why does a replaceable battery matter?
• What instructions would help a person fix this object?

What success looks like: The child can justify which object is easier to repair.

Guided Session 2: Design a Better Fix-It Object

Time: 20-25 minutes

Materials: paper, markers, Systems Log

Setup: Pick one object that seems hard to fix.

Activity steps:

1. Name what makes the current object hard to repair.
2. Redesign it with friendlier clues.
3. Add labels for parts, fasteners, and instructions.
4. Explain how the new design keeps the object in use longer.

What to ask:

• What is one change that would help most?
• Who would need to use that change?
• Would the redesign cost more time, money, or effort?

Draw It: Draw a repair-friendly toy or device and label its removable parts.

Talk About It:

• Why might a company choose a sealed design?
• Why might a family, school, library, or repair group want the fixable version instead?
• How does repair change the system path after something breaks?

What success looks like: The child can describe one realistic improvement that makes repair easier.

Systems Log

Use this simple entry:

What I noticed:
What moved:
Where it came from:
Where it went:
My drawing:
One question I still have:

Helpful prompts for this week:

• What I noticed: "A repair clue I saw was..."
• What moved: "The broken part could be replaced by..."
• Where it went: "If it cannot be repaired, it may go to..."
• My drawing: a repair-friendly redesign

Systems Thinking Move

An environmental system is made of connected parts. When one part changes, other parts may change too. Some changes are quick. Some changes take time. Some effects are easy to see, and some are hidden.

Learner questions:

• What parts are in this system?
• What moves through the system?
• What happens next when one part breaks?
• What part of the system could we change safely?
• What feedback loop might make waste grow or shrink?

Environmental Checkpoint

Repair claims, product labels, and ads can all be checked carefully.

• Who made this claim?
• What evidence shows the item is truly repair-friendly?
• Could a photo, label, review, or screenshot leave out important information?
• What should I check before I trust a repair or green claim?

Some environmental messages may include AI-generated or AI-edited images, summaries, or product claims. That does not automatically make them false, but it does mean we should check carefully.

Who Is Affected?

Some people have easier access to tools, repair help, spare parts, transportation, or replacement options. Some do not.

• Who benefits when repair is easy?
• Who is affected when replacement is the only easy option?
• Does everyone have the same choices, costs, or access?
• What would make the system fairer, safer, or easier to use?

Engineer Corner

Older learners and facilitators can park the policy and design-language here.

• Designed obsolescence and Right to Repair belong here, since laws and details change.
• A useful systems point: repair can reduce throughput by lowering how many new products need to be made.
• Manuals, parts access, standard fasteners, and replaceable batteries all strengthen the repair path.
