Review: ICT in our lives
Let us remember Theme 1. Technology is tools and ideas that solve problems. Explorers use photos from the sky, GPS, magnetometers and radar to find hidden things before they dig. Technology has four ages: Pre-Mechanical, Mechanical, Electro-Mechanical and Electronic. Electricity joined the machines in the Electro-Mechanical Age. A computer has hardware that you can touch and software that you cannot. Input devices, like a keyboard, send data in. Output devices, like a screen, bring information out. The operating system helps the program talk to the CPU, which follows the instructions. Assistive technology helps people of determination. When something goes wrong, stay calm, wait, check the connection, look for the file in the usual folder and ask a grown-up. We collect data, look for trends, draw graphs and report what we find.
| Pair of words | How they connect |
|---|---|
| keyboard and screen | the keyboard sends data in; the screen shows information out |
| operating system and CPU | the operating system passes instructions to the CPU, which processes them |
| survey and graph | a survey collects answers; a graph shows them clearly |
| Age | Years |
|---|---|
| Pre-Mechanical | 3000 BCE–1450 CE |
| Mechanical | 1450–1840 |
| Electro-Mechanical | 1840–1940 |
| Electronic | 1940–today |
Review quiz show. In groups of three, write six question cards: two about tools and the ages of technology, two about computers and software, and two about data and reports. Take turns to ask the group. Each right answer scores a point. The group with the most points chooses the next topic to practise.
