This essential book contains 100 exciting, ‘real-world’ science experiments that can be confidently carried out by any KS3 science teacher in a secondary school classroom. Divided into four areas, biology, chemistry, physics, and extended projects, each investigation is structured as a problem-solving activity, asking engaging questions such as, ‘Which brand of crisps would be best for a mountain hike?’, or ‘How long would a shark take to find a bleeding surfer?’. With background information outlining the key concepts behind each experiment, there are also helpful links to the curriculum, and suggestions for how to adapt the tasks to increase or decrease the challenge for your students.
