In these activities, from the Institute of Physics, students look at waves, speed, frequency, wavelength and wave graphs. They provide an opportunity to assess and build on prior knowledge.

In this topic, there are three learning episodes:

Episode 309: ...

Produced by Becta, this document contains examples which highlight ways in which ICT resources may be used effectively to support children's learning within secondary science.

The examples include:

• Sound and waves
• Forces and moments
• Disease and mortality
• Digestion and...

This video explains how to measure the speed of water waves using an alternative to the ripple tank wave experiment; water in a Gratnell tray. In order to calculate the speed of a wave, we need to measure the distance covered by a wave in the time it takes to cover that distance.

This series of learning episodes, from the Institute of Physics, looks at how waves add together by superposition. It follows a 'conceptual approach' by looking at superposition itself, followed by interference fringes and then diffraction.

The episodes in this topic are:

Episode 320:...

Through demonstrations, discussions and worked examples, students are introduced to the phenomenon of wave-particle duality. Students learn that electrons, which are often thought of as particles, can sometimes behave as waves.

Using a diagram of an open tube an explanation of possible wave patterns is built up.  Firstly, the fundamental mode of vibration is drawn, followed by the second and third harmonics.  For each illustration the number of waves is calculated, i.e, ^λ/₄, ³/₄ λ and ^5...

The video states that the velocity (v) of a wave moving along a string is related to the strings tension (T) and its mass per unit length (μ).  The unit of tension is the Newton (N) and the unit of mass/length is kg/m.

A simple interrogation of the formula v = √(T/ μ) shows that as T increases so too does...

This booklet contains a range of suggested teaching activities and contexts for teaching about waves at A level. Curriculum links include  progressive, longitudinal, transverse, stationary, waves, intensity, electromagnetic spectrum, properties of waves, refraction, total internal reflection, superposition,...

A Year Ten module from the Salters’ double award science course. Exercises on codes and signalling methods introduce ideas about communication. A study of the ear leads to sound communication systems such as radio and telephones. Lenses are studied and the formation of...

These diagnostic questions and response activities (contained in the zip file) support students in being able to:

• Use ray diagrams to show how light refracts at a boundary between transparent media.
• Describe rules for the refraction of light at a boundary between transparent media.
• ...

LDRs (light dependent resistors) are semiconductor devices. From the Institute of Physics, in this learning episode students investigate the resistance of an LDR at different light intensities. This can be used as a basis to explain how photons liberate free electrons...

In this SimPhysics game, players get the opportunity to manipulate sound, style a rock band and work on their recordings.

Players are presented with some wrinkles in the recorded sound that they have to iron out. On...

These activities from the BEST project can be used with primary pupils. The diagnostic question probes pupils' understanding of the different elements of a sound. The response activity helps to develop pupils' understanding of how the size and frequency of vibrations affect the volume and pitch of sounds and is...

Aimed at primary level, this resource provides a cross-curricular design and technology project linked to the topic of sound. Children design and make their own simple stringed instrument, so they can make a soundtrack for a movie clip. This enables them to learn and experience properties of sound and discover more...

A resource for...
