Produced by the Institute of Physics, this learning episode includes discussions, demonstrations and questions which introduce students to thermodynamics. These include compressing and expanding gases, adiabatic and isothermal changes.

In this learning episode, from the Institute of Physics, students look at heat engines to find out about their efficiency and this leads into a discussion of the second law of thermodynamics.

The activities include:...

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...

This resource from Inquiry Maths is designed to encourage students to explore relationships between the areas of different shapes. 

Equal areas contains the prompt showing a diagram containing rectangles, triangles and circles and asks whether their areas can be the same. There are suggested...
