Technology, 7–10 years — 20 topics · MyLeoNes™ Kuks
20 technology topics written for 7–10 years — not a older text simplified. In teaching order, each a deck of five cards: the idea, why it exists, a worked example, the common trap and where you meet it.
Technology · 7–10 years
Algorithms: instructions in order
An algorithm is a clear set of steps for reaching a result. People use algorithms in recipes, games and computer programs.
Debugging: finding and fixing mistakes
Debugging means checking why a plan or program did not work, then changing it carefully. It turns mistakes into clues instead of dead ends.
How messages travel on the internet
A message on the internet is broken into small pieces and sent through connected devices. The pieces can take different routes and are joined again at the destination.
Protecting personal information online
Personal information can identify or locate you, so it should not be shared casually. Strong passwords, careful choices and trusted adults help keep accounts and people safer.
Bits: how computers store information
A computer can keep pictures, words and sounds by using tiny choices between two states: usually 0 and 1.
Pixels: how screens make pictures
A digital picture is built from many tiny coloured squares. Looking closely at pixels explains both sharp images and blocky ones.
Sensors and outputs
Technology can notice something in the world and then respond. Sensors take in information; outputs show, move or play the result.
AI learns patterns from examples
Some computer programs find patterns in many examples instead of receiving every rule one by one. This can be useful, but it does not make the machine understand everything like a person.
Hardware and software
Computers need both things you can touch and instructions you can run. Seeing how they work together makes technology less mysterious.
Files and folders
Digital work needs a place and a name so you can find it again. Files and folders bring the order of a desk into a device.
Loops: repeating instructions
A loop lets a computer repeat a small set of instructions instead of writing the same steps again and again. It is useful when a job has a repeating pattern.
Technology that includes people
Devices can be designed so that more people can use them in different ways. Accessibility is not a special extra; it is thoughtful design for real human differences.
How search engines find things
A search engine helps you find useful pages among millions online. It does not understand every question like a person: it looks at words, stored information and other clues.
QR codes: patterns that carry information
A QR code turns information into a pattern of dark and light squares. A camera can read that pattern quickly and turn it into a link, a short message or another piece of data.
3D printing builds objects in layers
A 3D printer turns a digital shape into a real object by adding material one thin layer at a time. It is different from a normal printer because the result has height, width and depth.
What happens to old electronics
Phones, tablets and game consoles contain useful materials as well as substances that can cause harm if handled badly. Recycling electronics means collecting, sorting and processing them safely instead of putting them in an ordinary bin.
If–then choices in programs
A program can check what is happening and choose what to do next. This makes instructions react instead of always doing exactly the same thing.
Wi-Fi: connecting without a cable
Wi-Fi lets nearby devices exchange information using radio waves. It is not the same as the whole internet: it is often the short wireless link from a device to a router.
Databases: organised information
A database stores many pieces of information in an organised way, so a computer can find, sort or change them quickly. It is more useful than one enormous, untidy list.
GPS: finding a place with satellites
GPS helps a device estimate where it is by timing signals from satellites in space. It can guide a journey, but it is measuring a position, not magically seeing the road ahead.
