This online resource looks at the sensitivity of human hearing.

This free online hearing test measures the relative sensitivity of your ears at different frequencies using the audio capabilities of a computer.

It produces equal loudness contours or hearing sensitivity curves—the frequency response of a person’s ears and has been successfully trialled in a classroom situation where each student used their own ear plugs and computers.

The website also has a multimedia tutorial on the operation of the voice and hearing.

This unit of work supports younger students learning about change.

The resource is a teaching unit targeted at Year 1s that supports investigating and learning about the changes that occur to natural, managed and built environments. Students have the opportunity to investigate the daily, weekly and seasonal changes in their local environment through outdoor observations and photographic records. They observe sky and landscape over several timescales, and apply their new learning by investigating how human activities affect features of the landscape.

This online resource investigates the effects of heating and cooling.

The resource is a teaching unit that details ways of engaging Year 1 students with practical investigations into ways of using heating and cooling to change the properties of various substances.

This is an extensive teaching unit focused on learning about the ways heating and cooling change the properties of a substance.

It includes lesson plans, student handouts and other teaching resources, for six lessons.

This online resource investigates different sound frequencies.

The resource is an instructional guide for building pan pipes made of drinking straws to demonstrate that different musical notes have different frequencies.

The instructions include how long to cut each straw for particular notes, and a guide to playing basic nursery rhymes using a number system.

This activity would make a good introductory lesson to sound waves or an extension for more able students to discuss frequencies and resonance. It should take approximately 30 minutes.

This online resource simulates plate tectonics.

The resource is a simulation of tectonic plate movement that allows students to change the variables involved in the process and observe the impact of each change.

This online resource demonstrates how to simulate the rock cycle.

The resource is a step-by-step YouTube video guide for using wax crayons to demonstrate erosion and creation of sedimentary rocks as well as the link between sedimentary and metamorphic rock.

A worksheet is also available for students to use when replicating this task in class.

This online resource has an interactive map showing tectonic activity.

The map of the Earth have optional layers showing tectonic plate boundaries, volcanoes, earthquakes, types of boundaries etc.

There is also a teacher site that has worksheets and past exam questions from the UK.

Ideal as part of a web search, or to support a current unit of work.

This online resource gives comprehensive coverage of Earth's global systems.

The resource is a fully self-contained series of lessons concerning global systems including: the biosphere, the hydrosphere, the cryosphere, and the carbon cycle.

Four units illustrate a sequence for learning science concepts through data analysis activities, satellite imagery and computer visualisations, as well as hands-on experiments that illustrate processes of our Earth system.

This online resource looks at the effect on springs of falling masses.

The resource is a simulator that allows students to study the effect on springs of falling masses under various conditions.

Different masses can be added to up to 3 springs and their stiffness and damping can be adjusted.

The springs are extended and released and their motion can be analysed via energy graphs which show kinetic, potential, thermal and total energy.

These online interactives demonstrate the interaction of forces.

The resources are a number of downloadable interactive simulations that help explain the various forces acting on moving objects in terms of the mathematics involved.

Explore the forces at work when you try to push different objects along a flat surface. Create an applied force and see the resulting friction force and total force acting on the object.

See charts that show the forces, position, velocity, and acceleration v time.
