Vocabulaire des sciences et technologies

In science, we use specific words to describe the world. A 'laboratory' (or 'lab') is a room for experiments. An 'experiment' is a test to discover something. A 'hypothesis' is an idea you can test. 'Data' is information you collect. 'Evidence' is proof. For example: 'We did an experiment in the lab to test our hypothesis. The data gave us evidence.'

Technology is everywhere. A 'device' is a machine or tool. A 'smartphone' is a mobile phone with internet. A 'tablet' is a flat, touchscreen computer. A 'laptop' is a portable computer. 'Headphones' let you listen privately. A 'charger' gives power. Example: 'I use my laptop for homework and my smartphone to chat with friends.'

Scientists 'observe' (watch carefully), 'measure' (find size/amount), 'record' (write down), 'analyze' (study in detail), and 'invent' (create something new). With technology, we 'browse' the internet, 'download' files, 'upload' photos, 'stream' videos, and 'scroll' through pages. Example: 'I downloaded a new app to measure my steps.'

Let's combine nouns and verbs. 'The scientist used a microscope to observe cells.' 'I stream music on my tablet.' 'We recorded the temperature every hour.' 'She invented a new device to save energy.' Practice by describing your daily tech use or a simple science experiment you've done.
