Produced by Practical Action, Moja island is a 1-2 hour activity which will reinforce students' understanding of renewable energy sources. Students consider the variety of different options available to communities living on Moja Island and select the most appropriate technology. Renewable energy fact cards, a map...

This simulation explores the factors which determine the concentration of a solution. It illustrates the relationships between moles, litres and molarity by adjusting the amount of solute and solution volume.

The moles of solute and the volume of solution (water) can be changed using sliders to make...

In this video Helen describes how she became a trainee molecular geneticist at Addenbrookes hospital. The video could be used to introduce a lesson on  cystic fibrosis, genes, genetic testing, pre-implantation genetic testing, recessive and dominant genes, genetic disorders or genetic screening.

A Catalyst article looking at how modern archaeology uses analytical chemical techniques to answer questions about ancient civilisations and animals. Scientists working at the University of Bristol match compounds present in archaeological materials to those in modern plants and animals which were likely to have...

This simulation can be used to explore how light interacts with molecules in our atmosphere.

Sample learning objectives include:

*Explore how light interacts with molecules in our atmosphere

*Identify that absorption of light depends on the molecule and the type of light

*Relate the...

This resource includes a suite of games designed to promote thinking, learning and understanding as well as being enjoyable and engaging. They are all based around molecules that play key roles in life on Earth.

In the ...

Produced by LSIS, this short activity can be used to monitor and assess understanding of moments. It can also be used as an extension or reinforcement activity at the end of a topic on moments or as a revision activity. It is a useful way to check students’ familiarity with, and use of, the spoken and written...

This Catalyst article looks at how the laying of telegraph cables across the ocean bed led to the science of oceanography. Over two thirds of the Earth’s surface is covered in sea which can reach depths of 11 000 metres. The article looks at the challenge of laying cables in this environment and the history of the...

This resource shows what the lights on the front of the SAMHE monitor mean, so that students and teachers can understand what the air quality is indoors. Included is the A4 'Monitor LEDs' poster which provides an overview of what the LEDs on the front of your SAMHE monitor tell you about CO₂ levels, what...

This article focuses on how monitoring the movement of tectonic by satellites is allowing scientists to monitor the build-up...

From the National STEM Learning Centre, this short video illustrates the effect of gravity on a projectile's motion by using a classic physics demonstration called the Monkey and the Hunter. If a hunter fires horizontally at a monkey in a tree, and simultaneously the monkey releases their grip to fall off the tree...

On July 20, 1969, the astronaut Neil Armstrong was the first human to set foot on the moon. From NASA, these images illustrate the story behind "One small step for a man, one giant leap for mankind." Truly a milestone moment in space exploration.

• Describe the relationships between speed, frequency and wavelength for light waves.
• Describe the nature of light as a form of electromagnetic radiation....

In order to avoid predators, the caterpillars of some species of moths rest during the day by masquerading as twigs, well-camouflaged and keeping their bodies rigid and still. The aim of the investigation is to determine if caterpillars of the peppered moth show a preferred angle of rest. Students look at a series...

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

• Describe the magnetic field created by a current carrying wire.
• Describe the force acting on a current carrying wire in a uniform magnetic field.    
• Explain how a coil of...
