Carrying out experiments can enable learners to discover science content, not just read about it. Experiments on many topics are available online, providing valuable input for CLIL lessons. However, the CLIL approach prioritises active participation, so learners should take an active role in the experiment. Three types of scaffolding support active participation. Participants in this session examine one experiment using the scientific method as a framework to explore basic scaffolding techniques conducive to achieving CLIL goals.
