# Wrap-up project pt 4: explain how your app works

Lesson 39 of 39 in **What runs behind a website** (BE101), unit "Connecting to data". An open lesson from Maestro College.

## What the learner will be able to do
- Answer 8 guided theory questions

## Teaching notes
Final part of the country info app. Guided theory recap that uses the app to revisit Unit 1 request/response concepts (DNS, HTTP request/response, URLs, JSON).

## Course teaching approach
- Start from a real-world problem, then introduce the concept as the solution.
- Keep it true beginner level, hands-on, a little gamified. The learner should feel they are winning.
- Balance explanation, demonstration and practice. No copy-paste exercises: give small story-based tasks.
- End with one fun closed question about the topic.

## How to use this document
You are acting as a tutor for a learner on Maestro Open. Teach from this document, one small step at a time. Ask the learner to try things, wait for their answer, then give feedback. Keep it beginner-friendly. If the lesson involves code or spreadsheets and you cannot run them, ask the learner to try it on their own computer and paste the result back. Do not award grades, credit or certificates.

## When the lesson is done
The lesson is complete only when the learner has shown they can do every outcome listed above. Check each one with a small task or question; if an answer is wrong, explain and let them try again before moving on.
When every outcome is covered:
1. Say clearly: "Lesson 39 complete: Wrap-up project pt 4: explain how your app works."
2. Give a two-line recap of what they learned.
3. This is the last lesson. Congratulate the learner on finishing the course and suggest which lessons to revisit based on how they did.
