Produced for Future Morph, these resources consist of a short video and an accompanying classroom activity. In the video, a First Diploma in Animal Care student describes her work on the course. She illustrates how the course gives experience relevent to working in a range of environments including farming, zoos...

Produced for Future Morph, this short video shows the activities of a student studying a National Diploma in Land Based Technology at Bicton College. The student describes how the course develops skills in the maintenance and repair of machinery such as tractors, commercial vehicles and other agricultural...

Produced for Future Morph, this video clip shows an apprentice in motor vehicle maintenance talking about her work and college course. She describes how a car's engine is tested to find a fault with its fuelling. An additional activity describes a classroom demonstration that shows the products of hydrocarbon...

From Solar Spark, this activity allows students to see how chlorophyll can be energised and how this causes it to fluoresce. Chlorophyll in plant leaves absorb red light and pass the energy on to other parts of the plant, hence leaves look green. But if there is nowhere for the energy to go, it gets released as...

As the number of cells in a microbial culture increases, turbidity increases. In this experiment students calculate doubling time and growth rate constant using absorbance as the measure of growth. Turbidity is caused by suspended cells in the growth medium scattering light, and may be measured using a colorimeter...

This experiment is a continuation of Determining Doubling Time. Students create a standard curve of absorbance against yeast concentration, and use this to determine the concentration of yeast produced over time.

The standard curve (dry mass, grams per litre) is generated from known concentrations of dried...

From the Institute of Physics, this learning episode shows that charge carriers in good conductors usually move very slowly. It illustrates the derivation and use of the equation I = nAvq.

A range of activities include:
• viewing the movement of permanganate ions in an electric field
•...

This activity from the Institute of Physics discusses energy transfer in electric circuits and links this, by analogy, to other more familiar examples.

The activities include:
• demonstrations of human and lemon-powered batteries to illustrate that that there is nothing special about the chemical...

This series of activities, from the Institute of Physics, help student to understand electrical resistance. What is resistance, how it can be measured, how it arises and what affects it? During the topic, resistance is related to current, voltage, type of material, temperature and light intensity. The electrical...

From the Institute of Physics, this learning episode provides a quantitative definition for resistance (R = V / I) which reinforces the qualitative notion that more resistance means less current. It looks at Ohm’s law, describing that this is not the same thing as the definition of resistance.

Activities...

Produced by the Institute of Physics, in this practical investigation students measure the current and voltage characteristics for several components and identify ohmic and non-ohmic behaviour. Students determine the V-I characteristics for: • a carbon resistor • semiconductor diode • a filament lamp In addition,...

In this learning episode, from the Institute of Physics, students derive the equation relating electromotive force (emf), terminal potential difference, current and internal resistance. They then tackle questions about the internal resistance of a power supply.

This demonstration or student practical activity, from the Institute of Physics, helps students learn to use an oscilloscope to measure voltages. It helps students to understand the use of a cathode ray oscilloscope by showing:
• how the oscilloscope plots a graph...

Produced by the Institute of Physics, this learning episode helps students to distinguish alternating from direct currents before revising why alternating current (ac) is so important.

The range of activities include...
