A simple and effective practical demonstration of inertia using a spinning raw egg.

When the egg is spun its contents also spins.  Momentarily stopping the egg does not stop its contents from spinning.  On release the egg begins to spin again. The contents of the egg resist any change in its motion.

In this lesson, students look at fluctuations in electricity sources by analysing large data sets.  A student sheet is provided, containing data downloaded from MyGridGB - Charting GB Energy .  This site provides current data on sources of electrical power...

This film clip shows how steam is used to drive turbines in power stations which burn fossil fuels. It then looks at how turbines can be adapted to be driven by alternative energy sources, and examines the advantages and disadvantages of energy sources such as wind, to solar, biomass, hydroelectric power, tidal and...

This video revises the order of electromagnetic spectrum (GCSE) and introduces the range of magnitudes of wavelengths and corresponding frequencies for each type of electromagnetic radiation.

This video helps students to visualise the electric and magnetic field components of an electromagnetic wave.

The electric and magnetic oscillations (vibrations) are at 90⁰ to each other and also to the direction of energy propagation. 

A person is shown rolling down a hill, pausing, and then running back up the hill. The task is to draw a graph of their elevation against time. The graph contains increasing, decreasing, and constant sections.

A paper plane is thrown from the balcony of a house. The plane initially gains height before curving as it falls to the ground. The challenge is to graph the elevation of the plane against time. The resulting graph is non-linear.
