This simulation demonstrates how Ohm's law relates to a simple circuit. The voltage and resistance can be adjusted to see how this affects the current. The sizes of the symbols in the equation change to match the circuit diagram.

This online ecology practical, from SAPS, uses random sampling to measure the abundance of various different species on an area of grassland.

Objectives

To give students practice at

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 resource, aimed at Key Stages One and Two, links to the topic areas of animals, habitats, and adaptation. It includes a film showing footage of the behaviour of parental blue tits and a series of activity worksheets. These look at several aspects of blue tits and their behaviour including:

*What happens...

These downloadable videos and animations are part of the multimedia package Stuff and Substance, developed by the Gatsby Science Enhancement Programme (SEP). They can be used to introduce a particle model to explain why a substance can exist in both the solid and liquid...

From the Association of the British Pharmaceutical Industry (ABPI), this interactive resource halps to answer questions that students have about the production of medicines and the careers available in the pharmaceutical industry.

There is a wide variety of questions on topics as varied as:

• The...

In this simulation students can see how light knocks electrons off a metal target, and recreate the experiment that spawned the field of quantum mechanics.

[b]Sample Learning Objectives include:[/b]

*Visualize and describe the photoelectric effect experiment.

*Predict the results of experiments...

This resource, from the Association for Science Education (ASE), is a virtual model of our solar system. There are two main activities in this resource.
