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...

Funky Pigeons

These post-16 lesson plans look at Darwin’s pigeon breeding experiments and how they revealed the biology of inheritance and selection. Students will:

  • Compare natural and artificial selection and be able to critically explain the difference between the two.
  • Explore how Darwin used selective...

Introduction to Lowland Heathlands

This resource is an interactive activity which aims to provide an introduction to the lowland heathland habitat. The five topics relating to lowland heathlands covered by the resources include: • The biotic components of lowland heathlands, focusing on plants • The biotic components of lowland heathlands, focusing...

A-level set practicals: factors affecting rates of photosynthesis

This updated version of the SAPS algal balls resource is designed to support the use of practicals across 2015 A-level biology specifications.

Students measure the rate of photosynthesis in comparison to the rate of respiration. Because of this, it is possible to determine the light intensity at which the...

A-level set practicals: TLC of plant photosynthetic pigments

This resource, from SAPS, supports the use of practicals across 2015 A-level biology specifications.
