This Catalyst article investigates the development of better, more energy-efficient solar cells. Every minute enough sunlight strikes the Earth to power our civilisation for a year, yet less than 1% of global energy generation is provided by solar energy. Solar cells convert sunshine directly to electricity, but to...

Produced by Solar Spark, this activity looks at the relationship between light and absorption in solar cells. Using a photovoltaic cell and different colour acetate sheets, it demonstrates the ability of solar cells to absorb at different wavelengths of the electromagnetic spectrum and shows how the more it can...

Students investigate the generation of electricity by solar cells and how this can transform the lives of people without access to mains electricity.  The challenge is based on Practical Action's work in Gwanda, Zimbabwe.  

Reliance on unsafe drinking water is a significant problem in many areas of the world. This Catalyst article looks at the method of solar disinfection to provide safe drinking water.

UVA from the sun causes a breakdown in cellular functions, and combined with the increased temperature of the water from a...

Produced by the Technology Enhancement Programme (TEP), these images are useful for adding to documents and presentations, or for use with an interactive whiteboard. Mainly simple line drawings, they can be cut and pasted into documents and image processing applications. The images in this resource are related to...

This resource contains three activities and accompanying teachers’ notes.

Picking out the details
Using images from the...

This series of activities from NASA take a mathematical approach to looking at the Sun-Earth system. They are intended as supplementary problems for students looking for additional challenges in mathematics and physical science from age 11 to 16 years.

The problems were created to be authentic glimpses of...

From NASA, Solar Energy for Space Exploration is a problem-based learning activity. The project requires students to propose and defend a design to provide power to a lunar or Martian research base for six astronauts. To prepare for the final project, students investigate the variables that affect the operation of...

This booklet is part of the ‘Innovations in Practical Work’ series published by the Gatsby Science Enhancement Programme (SEP). Solar cells use light from the Sun to generate electricity, and it is now quite common to see solar-powered consumer devices. What has held...

A crowd funding web site recently raised more than two million US dollars to fund solar roadways. These roads, claim the developers, will remain snow-free, and, at the click of a switch, can be transformed into car parks or even sports pitches. In this activity students consider whether solar roadways are worth...

This Catalyst article is about the surface of the Sun. The article looks at a sunspot as seen by the Japanese Hinode solar observatory. Sunspots enable research about the nature and activity of the Sun. They are regions of strong magnetic activity and the article reports on the history of research into sunspots....

This resource provides an activity in which children create a scale representation of the distance of the Planets away from the Sun. Using the scale of one sheet of toilet paper = 50,000,000 km children calculate the number of sheets of toilet paper required for the correct spacing of the Planets from the Sun. This...

From NASA, this is a set of high quality images and information about the solar system. The set of materials features the Sun, Mercury, Venus, Earth, Earth’s Moon, Mars, Jupiter, Saturn, Uranus, Neptune, Pluto, asteroids, comets, meteors and meteorites, the Kuiper Belt and Oort Cloud, and moons of the solar system...

Produced by NASA, this activity contains information about the planets of the solar system. The main activity allows students to create an eight-cube paper puzzle of the solar system. In assembling the puzzle, students colour images of the Sun, planets and asteroids. In addition to puzzle pieces, the kit contains...
