Kavi Looks Back at Term 2

Kavi settled into the reading nook with acorn tea and a fat notebook. "Look how far we flew this term!" Kavi hooted, turning the pages. "We learned to debug — when a program misbehaves we don't guess, we use a method: reproduce the bug, locate the broken line by tracing, fix just one thing, then test. We looked inside the internet — many computers connected worldwide, where DNS turns a name like kavi.academy into an IP address, and messages travel as small numbered packets. And we learned security — encryption scrambles our data so snoopers can't read it, https:// with a padlock means a secure connection, and 2-step verification adds a one-time code on top of our password." Kavi tapped the three headings. "Three big ideas. Let's look back and make sure every one of them stuck."

2Sort each one into its big ideaEach card below belongs to one of the three big ideas. Tap the box it belongs in.

3Trace it, look it up, stay safeA good technologist can trace a bug, recall how the internet works, and make the safe choice. Work out each one, then reveal to check — and try the next.

4The internet, or the web?These two sound the same but are not. The internet is the computers and wires; the web is the pages you read on top of them.

A peek inside

Kavi's quiz game should score 3 out of 3, but it shows 2. What is the first move of the debug method — and why not just change lines and hope?

the method is reproduce, locate, fix, test — and it starts by making the bug happen again

Try this at home: The four steps of the debug method, in order, are reproduce, locate, fix and ____.
