In this resource from SAPS, students learn about random sampling, diversity and different measures of abundance, before looking at close-up photographs of quadrats and using the field guide to identify them. The resources are intended to help students develop skills and plant identification techniques before going...

This online ecology practical, by SAPS, is designed to give students an opportunity to see how systematic sampling can be used to

• investigate changes in species richness across a footpath
• the distribution of species across a footpath

These online exercises are not intended as a...

This Barefoot Computing resource for upper-primary computing lessons uses the creation of a Scratch maths quiz as a basis for learning about algorithms using selection.

Children are asked to create an algorithm that...

This Barefoot Computing resource builds on the ‘Maths quiz with selection’ learning activities which should be undertaken first.

It involves improving an existing Scratch maths quiz and adding score-keeping using...

In this activity, students explore the questions: What are the main sources of air pollution? What is the impact of transport emissions on air pollution and the natural environment? What can we do to reduce air pollution coming from transport? To what extent can emissions be reduced if solar powered cars instead of...

This activity introduces children to simulations - modelling or acting out real-world, or maybe imaginary, situations. Linking to the teaching of space, it asks what factors need to be considered when simulating the solar system. Out of these, the children then decide what the most important things to include in...

This animation shows the major stages of subcloning. This is the process of breaking up fragments of DNA from BAC clones into smaller more manageable pieces for DNA sequencing. This process was very important during the Human Genome Project. Subcloning involves several standard molecular biology techniques...
