This Catalyst article looks at sexual selection, a form of natural selection, and the role it plays in the evolution of many organisms. The article is from Catalyst: Secondary Science Review 2014, Volume 24, Issue 4.

This Revised Nuffield Option aimed to help students see their experience of elements and compounds in a more unified and coherent theoretical framework. The treatment was based on experiment but emphasised theory.

Contents

1. Periodicity

2. Atomic structure

3. Bonding...

This activity, from the Royal Observatory Greenwich, introduces students to ways of combining errors (uncertainties) from two independent measured quantities. Using the equation for Doppler shift, the error in the rotational velocity and time period are calculated....

Produced by The Centre for Industry Education Collaboration (CIEC), these materials look at nuclear fission and nuclear reactors.

The activities examine the trend in reactivity of the metals in group II of the periodic table and includes a brief study of isotopes in relation to nuclear fission and nuclear...

This Salters’ Chemistry Course unit from the University of York Science Education Group covered:
* The extraction and production of important materials from sulphide ores, iron ore and limestone.
* The use of relative atomic masses for determining the masses...

The contents of the Chemistry strand of Nuffield Co-ordinated Sciences were broadly the same in both the first and second editions of the publications. The second edition of the Teachers’ Guide showed how the course matched to the 1992 version of the National Curriculum.

Contents of both editions...

This mini-course from the Nuffield Exploratory Data Skills Project: Making Sense of Data is about how to deal with data in the form of counts. Such data, often transformed into percentages, are very common in newspapers as well as in technical reports and publicly available statistics. As a result of this mini-...

Work done in this Nuffield 13 - 16 module followed from the D unit called ‘The Periodic Table’. This D unit provided enough material for eight double periods during a Further Science course and built on the content of the S units for Single Science. The teachers’ guide...

This Catalyst article looks at the noble gases (Group 0 or 8 in the periodic table) which are almost inert. This article shows how they were discovered through the use of fractional distillation and looks at their chemical and physical properties.

This article is from Catalyst: GCSE Science Review 2011,...

This chemistry extension module from the Salters’ Science course deals with the energy changes which accompany chemical reactions. Photosynthesis is considered as the fundamental source of energy to sustain life process, and respiration as the mechanism for coupling the energy to body processes. ‘Calorific values’...

This Nuffield Pathways Through Science module began by exploring three questions related to chemical reactions: How much?, How fast? And How far? and went on to show how a model of atomic structure can account for the periodic table. Applications of chemistry related to...

The Nuffield Co-ordinated Sciences Chemistry book was printed in black-and-white in the first edition but illustrated in full colour in the second edition. There was no change in content between the two editions. The file for this resource is the second edition. The text included explanatory text, and questions....

These wide-ranging materials include interactive animations and print-based resources covering various science themes. The six major resources are: *Chemwars - an interactive game approach to teaching about reactivity, complete with video clips of the reactions *Generating resources - a selection of activities...

The Nuffield Pathways Through Science course was developed to align with the very innovative and successful modular science course created by the Northern Examining and Assessment Board (NEAB now merged into AQA). There were three Chemistry modules:
*Materials – featuring features solutions and a variety of...
