| Objective | ||
| The purpose of this lesson is to introduce some of the key ideas and terminology of waves using familiar examples such as ropes, string and 'slinky' coils. Students get to see that waves carry energy and that there are different types of waves. | ||
| Prescribed Focus Area | Skills Development | Content |
P2 A student applies the processes that are used to test and validate models, theories and laws of science with particular emphasis on first-hand investigations in physics |
P12.1 Students perform first-hand investigations P12.2 … gather first-hand information P13 … identify appropriate terminology and reporting styles to communicate information and understanding in physics. |
D1.2 Students learn to describe waves as a transfer of energy disturbance that may occur in one, two or three dimensions, depending on the nature of the wave and the medium. |
| Activity | Resources | Homework |
A1.1 Students perform a first-hand investigation to observe and gather information about the transmission of waves in: • slinky springs • water surfaces • ropes |
|
A1.2 Students present diagrammatic information about transverse and longitudinal waves, direction of particle movement and the direction of propagation A1.4 … present and analyse information from displacement-time graphs for transverse wave motion |
| Management issues | Nominal duration | |
| The homework exercises involve the students writing up their experimental work in their notebooks using diagrams and graphs to illustrate the key concepts. The homework would be due the following week. | 1 hour |
