In this article, a teacher shares their experience and approach, raising the questions learners need to ask themselves to ensure they have concluded a fully rounded investigation. This will give them the best opportunity for success in the classroom and in their exams.

Use the downloadable resources to take GCSE and equivalent classes step by step through the evaluation process to develop their higher order thinking skills. The student sheet (available as a scaffolded version) includes a glossary to help learners access the scientific terminology required for experiments and investigations. Find the answers and an example based on a rates of reaction practical in the teacher notes.
