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

• using random sampling to measure the abundance of various different species on an area of...

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...

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...

The rainforest interactive resource is provided by ASE and it includes images and information that is presented in text and symbol supported versions. The other resources provide ideas and examples on how you could be using symbols in your teaching to clarify meaning and understanding. The rainforest website can be...

The simulation can be used to:

*Relate the real-world example of making sandwiches to chemical reactions.

*Describe what limiting reactant means using examples of sandwiches and chemicals at a particle level.

*Identify the limiting reactant in a chemical reaction.

*Explain the Law of...

This simulation looks at resistance in a wire. Students can change the resistivity, length, and area to see how they affect the wire's resistance. The sizes of the symbols in the equation change along with the diagram of a wire as the variables are changed.

This animation, from the Wellcome Trust, illustrates how several species of the Schistosoma parasitic worms exploit humans and fresh water snails. The parasites use rivers and streams to transfer between the two animals, using each for a specific phase of its life cycle...

In this SimPhysics game, the challenge for players is to help a family stay warm through the worst winter on record. SimEnergy 1 simulates the factors involved in insulating a building and makes it more fun to learn the physics by taking an enquiry approach. Each round poses a different challenge for students to...

Like ‘The Sims’, in this SimPhysics game students look after a family and keep their home supplied with electricity. In the game scenario the government has set a carbon dioxide quota for each household, so limiting their contribution to climate change. The player has to invest in renewable sources of electricity...

In this SimPhysics game, players get the opportunity to manipulate sound, style a rock band and work on their recordings.

Players are presented with some wrinkles in the recorded sound that they have to iron out. On...

SimSpace is a SimPhysics game-based learning resource where players take on the role of space scientists, scouting the skies for Near Earth Objects (NEOs) that may pose a risk to life on Earth.

The premise is that...

This ABPI resource introduces skin structure and function, including temperature control and the role of the hypothalamus. Students can learn about common skin infections, such as athlete's foot, and skin cancer.
