This video covers the basics of state changes in water. It explains how the distance between molecules and their motion can be used to explain the three states of water (solid, liquid and gas).  

A big idea in chemistry is the idea of how substances behave and change. This is important because we are surrounded by objects made from different materials, each with their own physical properties that make them suitable or unsuitable for different purposes. How substances behave helps us to categorise them into...

Contrails occur when water vapour from jet engines condenses – only when the temperature and humidity conditions of the air is right. Contrails act like greenhouse gases. Marc Stettler from Imperial College, London is interested in guiding aircraft to fly where conditions are right, reducing contrail formation....

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

• Identify when an electrostatic force is acting in familiar situations. 
• Describe how objects with a positive or negative charge attract or repel other charged objects.
• ...

This STEM activity gives pupils the opportunity to investigate the effects of static electricity. Pupils will rub a balloon against their jumper and use the build-up of static charge to make tissue paper cat shapes pounce onto and stick to the balloon. They will then be encouraged to discuss and explain the outcome...

Statistics are a vital tool that can be used to define and solve a wide range of problems in everyday life. In this lesson students will revise and consolidate statistical techniques and then look at how these techniques were used to identify and overcome problems of air pollution in London in the 1950s and how...

A very useful guide to data analysis in post 16 biology investigations, published by SSERC.

The booklet has been written in a way that is accessible to both teachers and senior school students. The authors say that if you think incorporating statistics into the report of a biology investigation is difficult...

This Mathematics Matters case study, from the Institute of Mathematics and its Applications, discusses the importance of statistics and computing to developments in medical research. Sequencing the human genome was a fantastic achievement, but it was only the beginning. Now, statisticians are coming up with new...

A Year 11 module from the Salters’ Key Stage Four double award science course. This module explores the controlled and co-ordinated energy changes which maintain a complex series of interlinked metabolic processes in living tissues.

This activity, aimed at Key Stage Two, investigates a range of materials in the classroom, identifying by touch whether they are thermal conductors or thermal insulators. Children are then asked to plan the appropriate clothes to pack for hot and cold destinations, and...

From the Centre for Science Education, and with support from Shell Education services, these materials help children to design a game to test their hand control. The game makes use of the fact that electricity will only flow around a complete circuit.

Children need to navigate a wire loop along a bent wire...

In these two activities, from the Royal Observatory Greenwich, students use bearings to plot constellations. They are then asked to think about what they represent.

The Higher Level file has more complex...

We know that sometimes it can be difficult to visualise what STEM Ambassadors actually do.

Even after speaking to colleagues who are old hands at delivering activities, questions can still remain. Why do I need to meet the teacher first? What if the students are bored? How do I make it relevant? Where do I...
