Your first model-home fair test
A model home is a small, fair test of a real design idea. One feature changed, indoor and outdoor temperature compared, and a written design version — that is enough to start a real pattern.
Build a simple model
Shoebox, cardboard, or a kit — any size, as long as you can compare versions.
Name ONE feature to test
Insulation, windows, orientation, or roof colour — not several at once.
Place a thermometer inside
Same position each time, out of direct sun on the sensor itself.
Record outdoor temperature too
Indoor minus outdoor tells you more than indoor alone.
Leave it under similar conditions
Same time of day and similar weather so tests are comparable.
Write your design version
Version 1, 2, 3 — so you and others can trace what changed.
Tips & safety
- Quiet result?: A small difference is still real data — note it honestly rather than rounding up.
- Safety: Adult supervision for any cutting tools, hot glue, or craft knives.
- Cost: A shoebox model can cost under $10 — insulation scraps and card go a long way.

One feature changed from version 1 — insulation added, everything else the same.
Borrowed from MaramaTrap's example-photo pattern — works for every platform.
