Planning inquiry-based lesson on "General Wave Properties" with a focus on understanding of graph representation of transverse and longitudinal waves.
Tentative ideas:
Class: 308; Venue: Computer Lab 3;
Resources: slinky springs, web-based applets -

- powerful simulations to help students visualise wave motion graphical & representation
Activities:
1. introduction to wave properties and terms
2. group work - handle slinky springs to create transverse & longitudinal waves
3. pair work - explore features of waves using web-based applets with guided inquiry-based worksheet.
