### Highest Common Factors and Lowest Common Multiples

Highest common factor and lowest common multiple – The first example finds the highest common factor of 6 and 15 by listing all the factors of each number, highlighting all the common factors and indicating the highest common factor. A similar technique is used to find the lowest common multiple of 6 and 15....

### Stretches

[b]Stretch parallel to the y axis [/b] – looks at what happens to the graph of y=f(x) when it is transformed to give the graph of y=af(x). Starting with the graph of y = x[sup]2[/sup], different values of a are used to show that the graph is stretched from the x axis parallel to the y axis. The next example...

### Translations

[b]Translate parallel to the y axis [/b] – looks at what happens to the graph of y=f(x) when it is transformed to give the graph of y=f(x)±a. Starting with the graph of y = x[sup]2[/sup], different values of a are added or subtracted to the graph. The explanation continues to show that the graph is translated...

### Let's Doodle

This workshop or lesson activity makes use of a 3-D printing pen, and covers many computational thinking concepts as well as practical and evaluative skills applicable to design and technology.

The teacher guide includes a range of ‘unplugged’ computing activities – no programming is involved. The...

### The Habitable Zone

In this activity developed by the Institute of Physics, students investigate how temperature changes with distance from a heat source and relate this to planetary temperatures. After completing this activity, students should be able to:

*Understand that the temperature of a planet depends on its distance...

### Episode 313: Polarisation

This learning episode, from the Institute of Physics, help students to develop their idea of electromagnetic radiation and polarisation. The basic ideas are developed through demonstrations and experiments. The approach is non-mathematical. The activities include: * using polarising filters to observe polarisation...

### Episode 506: Particles as Waves *suitable for home teaching*

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.

...### Episode 502: The Photoelectric Effect

This learning episode, produced by the Institute of Physics, helps students to understand the photoelectric effect. A range of activities are described and these include: * demonstration of the photoelectric effect * discussion to summarise the phenomenon * using the photoelectric equation * the Millikan experiment...

### Episode 501: Spectra and Energy Levels

Produced by the Institute of Physics, this learning episode helps students to understand the emission spectra of white light and from standard discharge lamps. There are a range of activities that include discussion, demonstrations, experiments and calculations. The activities in this learning episode include: *...

### Episode 302: Simple Harmonic Motion Getting Mathematical

Produced by the Institute of Physics, this learning episode assists students to use a mathematical approach to simple harmonic motion, starting from its physical basis and the forces involved. In the activities, students look at: * restoring forces in simple harmonic motion (SHM) * graphical representations of SHM...
