A Nature of Science book which tells the story of how a cure was found for Scurvy, an illness that had been killing people for hundreds of years. The chapters are: 1. Magnetism and astronomy for voyages 2. 'The curse of the mouth' 3. Old theories and old cures 4. New medical science 5. The disease of rich babies 6...

These diagnostic questions and response activities (contained in the zip file) support students in being able to:

• Recall that the good health of all organisms can be compromised by diseases.

• Recall that diseases can be caused by germs, lifestyle, environment or information in the...

This A-level tutorial video follows on from the the distance, speed and time video.  It looks at the terms displacement and velocity and how they differ from speed and time.  An example of a displacement / time and velocity / time graph is given and discussed.  A...

The ability to accurately observe, dissect and record an organism is a key skill for biology students. Many students are intimidated by the idea of making a scientific drawing, and struggle to develop their skills in this area.

This resource is designed to meet the specifications for the A-level...

This resource is designed to meet the specifications for the A-level practical endorsement in England (CPAC). However, it will make a valuable guide to dissection and scientific drawing of a flower for those following a variety of different specifications.

The ability to accurately observe, dissect and...

This is one of the 18 Background Books published for Stage II of the Nuffield Chemistry Sample Scheme. The books were highly illustrated and designed to be attractive. This book explores the chemical ideas related to solubilility and solutions. The main ideas covered are:
*what happens when a substance...

What effect does acid have on sea life?

This unit follows on from 'Do you like your oceans still or sparkling?' The activity demonstrates the ability of an acidic substance (in this case vinegar) to dissolve sea shells.

Malt vinegar contains acetic...

With this a-level video tutorial, the presenter talks about how we get the equation speed = distance / time and then looks at the differences between a distance / time and a speed / time graph.  It also demonstrates what the area under the graph represents as well as the gradient.  This can be followed by the...

Produced by the Learning and Skills Improvement Service, this activity takes students through a step-by-step approach to understanding the basic principles of distance-time and velocity-time graphs. Working through the activity will help students to:
* Understand the terms distance, time, velocity and...

This is a modelling activity where students use sampling techniques to determine the distribution and abundance of organisms in a simulated habitat. Students will simulate the mark–release–recapture technique (Lincoln Index) for estimating population sizes of mobile species.
