Review: tools and technology around us
Let us review Theme 1 in five groups. One: networks. The internet reaches your home through a modem, then a router shares the connection, a switch sends data only to the right device, and devices join by cables (wired) or by Wi-Fi (wireless). Two: new technology. Virtual reality is a computer-made world you step into; augmented reality adds computer pictures to the real view; artificial intelligence learns from examples. Three: judging and finding. Ask the seven user-experience questions: accessible, credible, desirable, findable, usable, useful, valuable. A search engine is fast but needs checking; a general database holds articles on many subjects, and a subject database holds one topic; a catalogue lists one library. Four: mobile devices and systems. Phones and tablets are useful when used responsibly; open source means anyone may read and change the code. Five: HTML. A tag opens and closes a part of a page, and learning it helps you understand and build web pages, because it is a first computer language.

Dates They are sweet.
Exhibition stand plan. On one big sheet plan a stand about HTML and one cutting-edge technology. Draw the stand, write labels and captions for three pictures, and add three puzzle cards that visitors can solve: an order puzzle, a match puzzle and a find-the-mistake code puzzle. Swap puzzles with a partner and solve them.
