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...

This learning episode, from the Institute of Physics, guide students to measure specific heat capacities experimentally and then see how energy must be supplied (or rejected) to increase (or decrease) the temperature of a material. Calculations are used to quantify the...

In this learning episode, produced by the Institute of Physics, students investigate how energy is involved in changes of phase, even though there is no change of temperature.

Using discussion, examples and...

In this learning episode, from the Institute of Physics, students see that what we know about the Universe comes from observations which rely on the radiation and particles that reach us on Earth. Students discuss astronomical observations including spectra and the information they can carry.

The activities...

Produced by the Institute of Physics, these activities demonstrate the Doppler effect.

Using sound and microwaves, the activities illustrate how changes in wavelength of spectral lines allow us to determine the motion of astronomical objects relative to ourselves.

The activities include:
*...

The ‘Experimenting with Industry’ series was published in the mid-1980s when it presented industry-related science practicals for schools. It was developed as part of a 'teachers into industry' project organised by The Association for Science Education (ASE) on behalf...

In this video independent and dependent variables are discussed, before experimenting with a trolley on an inclined ramp. The data is then graphed and analysed to investigate any relationship between ramp height and trolley speed. This is a GCSE Physics Practical.

A pair of videos that investigates the extension of a spring when forces are added.  The first allows students to see the experiment undertaken. This is a required practical for students to understand and be able to carry out for GCSE Combined Science and Physics. The second clip explains how to plot a graph to...

A pair of videos that investigates the extension of an elastic band when forces are added.  The first allows students to see the experiment undertaken and the second clip explains how to plot a graph to evaluate the relationship.

This video introduces permanent magnets, their fields and how to investigate them using iron filings. It also demonstrates the field between attracting and repelling magnets. 

The resources in this collection support the teaching of the following key concepts in the topic of forces:

• What forces do

• Describing forces

• Balanced and unbalanced forces

• Friction

• Energy stores and transfers

These diagnostic questions and response activities (contained in the zip file) support students in being able to:

• Describe the cause of friction between two objects.

• Explain how friction, generated by the interaction between two objects, can stop them from moving...
