👩‍🏫 Teacher’s Guide

Objective
Students will explain an API as a way for programs to communicate and give simple examples such as weather apps and map apps using information from another service.

Teaching Notes

• Use a restaurant analogy: menu (API) and ordering (request/response).
• Explain that APIs let apps use features or data from other services.
• Keep examples simple: weather data, maps, translation, login.
• Reinforce safety: APIs can share data, so privacy rules matter.

🧒 Student Worksheet

Concept and Helping Material

An API (Application Programming Interface) is a way for programs to communicate. One program can request information or services from another program, and get a response. Many apps use APIs to get data like weather, maps, or videos.

Computer Vocabulary and Definition

• — A way for programs to communicate and share data or services.
• — A message asking for information.
• — A message that returns information.
• — A system that provides data or actions to others.
• — Information sent and received by programs.

Computer QA

1. What is an API?
2. What is a request?
3. What is a response?
4. What is a service?
5. What is data?
6. True or False: Apps can use APIs to get information.
7. Why do apps use APIs?
8. What is one example of an app that might use an API?
9. What might a weather API return?
10. What might a map API return?
11. What is the pattern often called?
12. True or False: APIs help programs work together.
13. Can a game use an API?
14. Can a school app use an API?
15. Why should privacy matter with APIs?
16. What should you avoid sharing in apps?
17. True or False: APIs are only for computers, not phones.
18. Who uses APIs?
19. What is one benefit of APIs?
20. What is one safe rule about data in APIs?

Computer Prtactices

• Menu analogy: Draw a menu (API), order (request), and food (response).
• API spotting: List 3 apps that might use APIs (weather, maps, music).
• Request/response matching: Match requests to possible responses (forecast → temperature).
• Privacy check: Write 4 rules for safe data sharing when using apps.

Reflection

• What is an API in simple words?
• Why can APIs be helpful?
