History of Computers Lesson 20: AI on Your Own Desk (128 GB desktop machines, the series finale) - printable lesson, ages 11-14

A ready-to-teach lesson that follows our free video, step by step.

Watch a part. Pause. Talk. Try it. Then press play again.

The story (the series finale): small desktop computers of 2025 and 2026 with 128 GB of memory shared by the whole system, what their makers say they can run, why the largest models still run in data centres, and a look back from the abacus and ENIAC.

What you get (13-page printable PDF):

- A one-page guide for the grown-up, with the exact times to pause the video

- Key words, and a "think first" question

- Four pupil pages, one for each part of the video: what we just heard, two questions to talk about, and something to try

- Two worksheets: "will it fit?" memory sums with counters (our own round numbers), a timeline card sort across the whole series, weight and size comparisons, a matching task, and a cut-out timeline. Nothing in the lesson needs a computer or an AI tool.

- The story in four pictures, and an 8-question quiz

- All the answers, teaching notes, and the sources for every fact

For ages 11 to 14 (works from 9 with help). About 45 minutes. You need a pencil, a rubber, scissors, plain paper and 12 counters.

Every drawing and every word is our own. The free video is at kitson-workshop.pages.dev/#history
