### In the lessons

In science it is the heart of learning: a fair test changes one thing (the variable) and keeps everything else the same; you predict, test, measure, record results and draw a conclusion. In art and cooking you experiment with materials and recipes. In safety: experiments are done only with a teacher or adult, wearing goggles if needed — never mix household chemicals to «experiment». Phrases: do an experiment, carry out an experiment, a fair test, experiment with, science experiment.
