This video demonstrates an experiment to investigate how current affects the strength of a magnetic field. The Phyphox app on a mobile phone is used to measure the magnetic field strength. The second part explains how to plot a graph to evaluate the relationship between current and magnetic field strength. 

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 video demonstrates an investigation of reflection at a plane mirror.  This is a required practical for students to be able to understand and carry out for GCSE Combined Science and Physics.

Through demonstrations and discussions, this learning episode from the Institute of Physics helps students to understand the main features of simple harmonic motion. This is in preparation to moving to a more mathematical description. Activities include: * observing simple harmonic motion (SHM) * discussing the...

From the Institute of Physics, this learning episode introduces the idea that vibrations can give rise to disturbances travelling outwards, i.e. to progressive waves. This illustrates some of the basic properties of waves. The activities include: • investigating transverse and longitudinal waves in a spring •...

Produced by the Institute of Physics, this learning episode considers the forces acting on a falling body in air and moves on to related experimental work.

The activities include:
• demonstrating the motion of...

This learning episode, from the Institute of Physics, looks at kinetic energy, work and velocity in relation to the braking distance of a vehicle. Two experiments are included, both of which connect work done in braking to the initial kinetic energy of the decelerating vehicle. The activities include: • discussion...

In this learning episode from the Institute of Physics, students use Hooke's law to demonstrate the strength and stiffness of materials when subject to linear tensile or compressive forces. The activities include: • recap of Hooke's law • explaining tension and extension in a variety of materials • explaining...

From the Institute of Physics, this learning episode will help students to see how energy moves from an oscillating system and how this results in a decrease in amplitude that follows an exponential decay pattern.

The activities include:
• observing water oscillating in a u-tube
• the motion of...

In this learning episode, from the Institute of Physics, students look at how a magnetic field can be quantified by measuring the force on a conductor. It illustrates how Flemming's left hand rule can be used to find the direction of the force. The activities include: 

• investigating the relationship...

From the Institute of Physics, these demonstrations, computer model and associated discussions help students to look at Brownian motion as evidence for the particulate nature of matter, and the macroscopic gas laws. The learning episode looks at: * Brownian motion and what it tells us about gases * investigating...

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.

This video clip demonstrates an investigation into the absorption of infrared radiation by different surfaces. This is a required practical for students to understand and be able to carry out for GCSE Combined Science and Physics.

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...

In these activities, from the Institute of Physics, the concept of electrical power is explored. Students find that the energy transferred by an electrical component depends on the potential difference, current and the time for which it operates.
