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...

From the Institute of Physics, these learning episodes act as an introduction to cosmology and ideas about the history of the Universe. Most students should have heard of the Big Bang and expanding Universe. This topic makes it all plausible and looks at the wave speed formula, diffraction by a grating and the...

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:
*...

From the Institute of Physics, these resources help students to understand that cosmology is the study of the Universe, its origins, history and possible future. In these activities, students look at the expanding universe and cosmology. There are two learning episodes in this topic:...

Produced by the Institute of Physics, in this learning episode, students look at the expanding universe by examining galaxies, Hubble's observations and cosmological red shift. A simple activity allows students to model Hubble's law.

Through discussion and activities, students look at:
* observing a...

From the Institute of Physics, these activities encourage students to discuss the origins, history and future of the universe. Through a range of discussions and activities, students look at:
• the hot big bang
• the age of the Universe
• cosmic microwave background radiation
• the future of...

Produced for the Department for Education, this document outlines support materials for students aged 16-19 on issues relating to ethnicity, gender, disaffection, learners with special educational needs and gifted young people.

In this problem students are given two circles with tangents that meet at a point P. The distance along the tangents from the circles to the point P are equal in length. The challenge is to describe the relationship between the x and y coordinates of the point P, given the coordinates of the centre of the circles...

This activity requires students to calculate net income after tax and national insurance have been deducted. Students then are asked to discuss if the progressive taxation system is fair. Answers to each of the calculations are available.

The presentation shows how income tax and national insurance rates are...
