This is a lesson plan for a GCSE class to investigate the relationship between frequency and wavelength leading to the equation c = frequency x wavelength using fun demonstrations based on sound.

The lesson plan meets the needs of four GCSE exam board syllabuses. A variety of learning and teaching styles are considered to make the lesson plan appealing, from a learning perspective, to as many students as possible. The learning outcome is to teach students the inverse relationship between frequency and wavelength through a series of mini experiments in the classroom.

Students work in small groups and are equipped with a worksheet to fill in as they move around the classroom and do a set of short mini experiments, at each one, they have to record their results. The worksheet can also be used as a revision tool.
