1.1.1 — Defining Computer Science in Everyday Life

Students identify computing where no code is visible, defend their choices with evidence from everyday scenes, plan and test a practical sequence, and transfer the idea of input, rules, and output to a new device.

Set the Lesson Goal

Predict what counts as computer science before you inspect the scenes.

Objectives

Identify examples of computing embedded in ordinary environments.
Distinguish computational systems from non-computational tools using evidence.
Translate an everyday process into an ordered set of actionable steps.
Use computing terms such as input, data, rules, output, and sensor to justify claims.

Warm-up prompt

In this lesson, a system input, a rule, and an output matter more than whether you can see code running on a screen.

Which description best matches computer science in everyday life?

It only counts when someone is typing code on a screen. It includes systems that collect data, follow rules, and produce outputs even when no code is visible. It is mostly about being connected to the internet.

Choose the best description, then check your answer.

Spot the CS

Inspect three scenes, confirm the systems that compute, then certify each scene with evidence.

You will move through the home, school, and city scenes in order. Select one system at a time, read the feedback right away, and then pass a short reasoning check before the scene is fully certified.

Choose a system you might see in a home

Pick the device or tool that best fits the current location, then use the feedback to revise if needed.

Feedback

Select a system to see why it is, or is not, a strong example of computing.

Certify this scene

Find every required system in the current scene to unlock its certification question.

Finish identifying the required systems first, then certify the scene with evidence.

Human Algorithm

Plan the route, test it, then explain the dependency that mattered most.

What is going on?

A helper bot starts at the classroom door and needs to reach the laptop in the lab area. The bot only follows the commands you give it, in order, and it stops as soon as a step is missing or out of place.

Goal: Build a sequence that gets the helper bot from the classroom door to the laptop.

First think through the route, then build it, run it, and revise it based on the feedback.

Plan first

Before you run the bot, answer these two questions so you have to think about the route dependencies instead of guessing.

1. Before the bot can turn toward the lab wing, what must already be true? The bot must have already moved out of the classroom and into the hallway. The bot must know where the laptop is. All five steps must already be filled in.

2. If the bot reaches the lab door and then repeats the step 'Move out to the hallway,' what should you expect? The route still works because the step is always useful. The bot would move backward in the route, undoing progress toward the laptop. The bot skips ahead to the laptop automatically.

Answer both planning questions to unlock Run.

Command bank

Select the commands and arrange them in the correct order, then run the bot. You can run the bot even if some later slots are blank.

Build the route

Place commands in order. The route board updates immediately when you add, move, or remove a command.

You can arrange cards now, but Run unlocks only after the planning check passes.

Live route preview

The board shows where the bot would be after the commands currently in the lane.

Goal: Build a sequence that gets the helper bot from the classroom door to the laptop.

Answer the planning questions first, then run the bot to test your sequence.
