This experiment provides a quick and eye-catching way to teach about the vascular tissue in plants and the structure of plant stems. It provides students with the opportunity to develop (and demonstrate) their scientific drawing skills as well as their use of a light microscope and eye-piece graticule.

The...

This updated version of the SAPS algal balls resource is designed to support the use of practicals across 2015 A-level biology specifications.

Students measure the rate of photosynthesis in comparison to the rate of respiration. Because of this, it is possible to determine the light intensity at which the...

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...

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.

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...

In this learning episode from the Institute of Physics, students are introduced to capacitors. Through practical investigations, students look at their charge and discharge process.

The activities include:
•...

This learning episode, from the Institute of Physics, helps students understand how capacitors charge and the concept of capacitance. Students investigate the relationship between charge and potential difference across a capacitor.

In this learning episode, from the Institute of Physics, students derive formulae for capacitors in series and parallel to reinforce their understanding of circuits involving capacitors.

The activities in this...

Produced by the Institute of Physics, this learning episode looks at the energy stored in a capacitor. Students undertake a practical investigation to look at the energy stored and how this varies with potential difference and capacitance.

In this learning episode from the Institute of Physics, students investigate and characterise the exponential discharge of a capacitor.

Activities include:
• looking at exponential discharge
•...

This learning episode from the Institute of Physics, uses discussion and experimental work to help students investigate the application of moments beyond the simple 'see-saw' model.

Activities lead to an application of moments to general equilibrium situations.

Students look at:
* moments and...

From the Institute of Physics, this episode introduces (or revises) the equations of motion. During a practical task, students undertake direct measurements to ensure that they understand the basic physics of velocity, distance and time.

Activities help students to understand:
• scalars and vectors,...

This learning episode, from the Institute of Physics, looks at basic kinematics and introduces the equations of motion for uniform acceleration. It involves practicing calculations and compares uniform with non-uniform acceleration.

Activities look at:
• non-uniform acceleration down a ramp
•...
