In this activity students investigate the mystery of a light beam which seems to bend.  Students can investigate:

• Qualitative behaviour of light  when the medium in which it propagates changes its refraction index. 
• Quantitative evaluation of the behaviour of light in refraction by means of...

For this A-level investigation students use a deflection tube to measure the specific charge for the electron.  This worksheet provides step-by-step guidance and the calculations that are required to make this measurement.

This resource has been provided by Keith Gibbs.

Like the Deflection tube investigation this allows A-level students to measure the specific charge for an electron. It provides a step-by-step guide, along with the calculations that are required to find this measurement.

Produced by the Institute of Physics, this learning episode introduce students to electric fields, field lines and equipotentials. Similarities with gravitational fields are highlighted, but with the need to take account of the of charge.

The activities include:
• discussion and demonstration of field...

In this lesson students learn about the physical, chemical and bacterial contamination of food at different stages of processing and production. They also learn about positive micro bacterial changes, such as in the production of yoghurt and some cheeses, and the conditions in which micro-organisms survive and...

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...

This resource looks at how mystery objects can be used in class to introduce a topic, introduce new scientific equipment or vocabulary, or to explore changes in science and technology over time. Ideas are provided for effective questioning and how to structure the activity.

Published by the Nuffield Foundation, the Nuffield Advanced Biology Topic Reviews for students were an integral part of the Advanced Biological Science materials, but each could be read on its own. Thus, students could use them for their current work, or to pursue personal interests.

This topic review...

This resource linked to the topic of seasonal changes contains a display banner showing the changing of the seasons from Spring to Summer, Autumn to Winter. It is ideal to use as part of a classroom display when discussing the different seasons in early years and lower primary. The display poster has been provided...

Most current theories of adaptation and evolution are based on an organism’s inflexible genetic inheritance, where variation depends on chance mutations to the DNA sequence. Now, biologists studying epigenetics are trying to uncover the roles of this more flexible system.

This resource shows an example of how to create condensation and precipitation in a jar. It could be used when looking at changes of state and the water cycle.

Aimed at primary level this activity has been provided by BAE Systems.

In this activity students are asked to challenge assumptions made surrounding the selection of random numbers. For simple random sampling every member of the population requires an equal chance of being chosen. Students are required to use this spreadsheet to investigate for numbers up to 30.

Focusing on the programming skill of loops and repetition, this activity offers a chance for pupils to apply their understanding, linking both Scratch and art. With links to modelled examples, teachers could apply the PRIMM method to their lessons, through the pre-created Scratch projects.

This Unilever Laboratory Experiment, published in 1967, describes an experiment to measure the contraction of hair in a hot solution of phenol. The procedure is based on a school-made apparatus to measure the changes of length. The results are discussed in terms of hydrogen bonding and disulphide bonds between...

These activities from Cre8ate maths explore the efficient use of space in car parks. These are two-dimensional ‘best fit’ problems which require logic and a systematic approach to find effective solutions. They give students the chance to devise and test out strategies using systematic trial-and-improvement...
