This lesson has been designed to extend the more able following initial work on the Haber-Bosch process. It begins by viewing the video, which outlines why we need the process, problems associated with it and ways in which researchers at the University of Oxford are...

This activity gives children a chance to bring their own ideas and materials and try to grow some plants from their seeds. Children bring in all kinds of seeds such as: conkers, acorns, and apple pips, provide the conditions for germination and observe them over time to...

This resource provides a structured approach and a set of questions to guide students' research into changing use of energy sources, looking at how and why the types of energy sources for domestic use have changed over time.

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

• Make qualitative predictions about the resulting temperature when hot and cold water are mixed

• Make quantitative predictions about the resulting temperature when hot...

This book from the SISCON series looks at the history of scientific theories, including evidence, prediction and creativity. It asks questions such as: What is it possible to be certain about? Are experts always right?

This video explains how n-type and p-type semiconductors can be used to create a transistor.

The explanation

n-type semiconductors are made from silicon that has been doped with phosphorous.  The additional electron from the P can be used to form a current. P-type semiconductors are...

There is a minimum size of meteorite that will make it through the atmosphere of a planet (or the Moon) and impact on the surface. If the meteorite is any smaller than this, it will burn up on its journey through the atmosphere and be seen as a meteor or shooting star (obviously if the meteorite is bigger it will...

Science in a topic students’ book In the air covers both the inanimate objects which can be made to fly or stay up in the air and the organisms which can travel through the air. Activities lead students to explore the composition of the air, its pressure, the atmosphere and the changes in it which produce our...

This lesson develops the concept of percentage increase and decrease. In particular students will develop their understanding of:

• Translating between percentages, decimals, and fractions.
• Representing percent increase and decrease as multiplication.
• Recognizing the relationship...

A magical demonstration where it appears that pouring a jug of water into different glasses produces a range of different drinks.  It is a great way to introduce a lesson on pH indicators at Key Stage Three and will hold students spellbound. Chemistry teacher Paul Grooby shows a starter demonstration, adding...

These resources from the Wellcome Trust explore how imaging research has changed the way we look inside one of our most fascinating organs, the brain. ...

This resource develops the concept of using a distance time scatter plot, finding a function that links the variables, and then using the results to decide upon a rate. 

The resource is set in the practical context of distances and times a taxi cab takes for 40 journeys. The resulting scatter plot is used to...

This starter activity can be used as an introduction to reverse engineering. Using the presentation Earphones and Headphones, students are asked to identify the product and its function. They consider the following questions:

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

• Use the idea that organisms can be classified into groups within larger groups.  
• Recognise that organisms can be classified using evidence of their microscopic cell structures in...
