Dive into the world of investigations with this KS2 Science quiz – the first of three quizzes on the language of science, focusing on words like 'variable' and 'measure'.
Scientists use special words to understand things, and these words form the language of investigations. A 'variable' is something in an experiment that can change, and 'measure' is used to gauge various things, like the number of leaves on a plant or the taste of something. When you do an investigation, you're a real scientist, so using the right words is important!
