This resources provides a template for creating a model of the DNA double helix.  The class should collaborate on one model. Each student should make just...

This excel file looks at using the sine curve to model the water depth in a tidal river.

The first interactive sheet shows how the Earth’s orbit around the Sun can be modelled by the sine curve. One or two cycles can...

This article investigates the history of models of the atom and discovers how, a century ago, scientists were devising models of the atom in an attempt to explain the limited evidence they had about the fundamental structure of matter.

The article is from Catalyst: Secondary Science Review 2015, Volume 25,...

This interactive program deals with the modulus function applied to linear, quadratic, reciprocal and sine functions. The graph of each function is shown as well as the unreflected sections of the graphs.

The first...

This simulation explores the factors which determine the concentration of a solution. It illustrates the relationships between moles, litres and molarity by adjusting the amount of solute and solution volume.

The moles of solute and the volume of solution (water) can be changed using sliders to make...

The Association of the British Pharmaceutical Industry represents the manufacturers of most of the medicines and vaccines supplied to the National Health Service, in the UK. As part of their programme to encourage the study of science in schools, in 1995, the ABPI produced a book for post-16 students, on the...

In this video Helen describes how she became a trainee molecular geneticist at Addenbrookes hospital. The video could be used to introduce a lesson on  cystic fibrosis, genes, genetic testing, pre-implantation genetic testing, recessive and dominant genes, genetic disorders or genetic screening.

This simulation allows students to explore molecule shapes by building molecules in 3D and seeing how the molecule's shape changes as atoms are added.

It can be used to demonstrate that:

*The molecule shape is due to repulsions between atoms.

*The bonds are not fixed in place, but can rotate...

A Catalyst article looking at how modern archaeology uses analytical chemical techniques to answer questions about ancient civilisations and animals. Scientists working at the University of Bristol match compounds present in archaeological materials to those in modern plants and animals which were likely to have...

This simulation can be used to explore how light interacts with molecules in our atmosphere.

Sample learning objectives include:

*Explore how light interacts with molecules in our atmosphere

*Identify that absorption of light depends on the molecule and the type of light

*Relate the...

An interesting investigation to see what factors can affect the moment of inertia of a flywheel.  This is good to discuss errors in measurements (such as counting rotations) and would be good to develop improvements.

This resource has been provided by Keith Gibbs.

This series of interactive excel sheets investigate models involving moments.

The first sheet helps students to investigate the moment of a force about a point. The components of the force can also be revealed.

Produced by LSIS, this short activity can be used to monitor and assess understanding of moments. It can also be used as an extension or reinforcement activity at the end of a topic on moments or as a revision activity. It is a useful way to check students’ familiarity with, and use of, the spoken and written...

This collection of Level 1 resources from Nuffield Mathematics covers Money management. The demand is roughly equivalent to that in Foundation Level GCSE and Level 1 Functional Mathematics.

This Catalyst article looks at how the laying of telegraph cables across the ocean bed led to the science of oceanography. Over two thirds of the Earth’s surface is covered in sea which can reach depths of 11 000 metres. The article looks at the challenge of laying cables in this environment and the history of the...
