The Big Bang Lesson *suitable for home teaching*

The lesson activities and resources for 'The Big Bang Lesson' are provided here for teachers and lecturers to use in their own schools and colleges.

The lesson outline includes links to many of the presentation slides...

Model the Motion

In this activity from the Nuffield Foundation, students match descriptions of a variety of real scenarios involving motion with the corresponding velocity–time and displacement–time graphs. Several issues will be discussed while completing this task and students will also have to consider how realistic or...

Going Bananas about Radioactivity

This Catalyst article looks at how humans are exposed to radiation from many different sources, including food. The article describes the doses of radiation from sources such as:

  • building materials and rocks
  • bananas
  • bone scans
  • cosmic rays
  • radon gas


Banana Blues

This article from Catalyst looks at the ageing process in bananas. As bananas age, spots develop on their skins. These contain fluorescent substances which can be seen with a UV torch.

The article is from Catalyst: Secondary Science Review 2014, Volume 25, Issue 2.


pH Scale *suitable for home teaching*

This simulation allows students to test the pH of substances like coffee, spit, and soap to determine whether each is acidic, basic, or neutral. It can be used to visualise the relative number of hydroxide ions and hydronium ions in solution, switch between logarithmic and linear scales, and investigate whether...

Electric Motor

Produced by the National STEM Centre and the Institute of Physics, this video shows a simple method for making an electric motor using a battery, strong magnets and a copper coil. It allows students to investigate Fleming's left hand rule and the forces generated in an electric motor.

Water Movement in Potatoes *suitable for home teaching*

This Catalyst article investigates osmosis: when water enters or leaves plant tissue (raw potato) according to the concentration of water in its surroundings.

The article is from Catalyst: Secondary Science Review 2014, Volume 25, Issue 3.


Who's Who? *suitable for home teaching*

This worksheet, from the Linnean Society, looks at speciation, dimorphic and polymorphic species and Batesian mimicry. In Batesian mimicry a palatable species mimics an unpalatable one, thus protecting itself from predation. Through a series of questions based on the text, the resource aims to explore this in...

Who Are You? *suitable for home teaching*

The Linnaean collections hold many types of specimens (the first member of species to be scientifically described) for taxonomic study. Making use of the Linnaean collection online, this worksheet focuses on Hymenoptera (including bees, wasps and ants). It looks at the importance of the hymenopterans, particularly...

Investigating the Concept of a Niche *suitable for home teaching*

From Nelson Thornes, these activities encourage students to consider their understanding of an ecological niche. Students investigate the idea of a niche and look at the concepts of a fundamental niche and a realised niche. They are also asked to use information on a particular species’ niche, to predict where we...
