This practical activity allows students to explore how nature creates calcium carbonate, a compound needed to manufacture cement, at ambient temperatures and using abundant, readily available raw materials. The cement used in concrete is manufactured from calcium carbonate, which is extracted from open-pit mines....

Produced by Solar Spark, this activity allows students to see a condensation polymerisation reaction in action as the polyamide polymer, Nylon, is produced. This is a condensation polymer made of two parent monomers, a di-amine and a di-acid chloride.

The reaction can be used to illustrate:
*...

This downloadable video is part of the multimedia package Stuff and Substance, developed by the Gatsby Science Enhancement Programme (SEP). It can be used to show water condensing out of the air. A pure sample of water is normally in the liquid state at room temperature, but water particles can remain separated...

This video is the full experiment in real time to investigate the rate of conduction in various metals.

This Pedagogics resource uses the following quote from the Chinese philosopher Confucius: "Tell me...and I will forget. Show me... and I will remember. Involve me... and I will understand"

This article discusses how simple observations of pests on horse chestnut trees can contribute to a 'citizen science' project. The article is from Catalyst: Secondary Science Review 2015, Volume 25, Issue 4.

Produced by the LSIS, this practical activity is designed to engage learners in discussion about momentum and to help them to predict the possible effects of a collision. You may choose to perform a demonstration, using a simple runway, ball bearings and magnets, and then ask pairs or groups of students to try it...

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

• Select a particle diagram to correctly show the rearrangement of atoms during a chemical reaction.

• Interpret the quantitative meaning of a chemical equation.

This video demonstrates how the gravitational potential energy of a skateboarder is converted into kinetic energy as they move down a ramp.  It discusses efficiency and how you can calculate the energy mathematically at both stages.  It also ties into SUVAT and demonstrates how an objects acceleration due to...

From the Centre for Science Education, the RA3 project aims to bring parents together with their children and teachers to explore the worlds of science and technology.

The aim of this activity is to help children and parents think about the area they live in and how it could be improved. They work together...

These technical briefs look at the ways Practical Action have helped poor communities to make the best use of their own labour and to use locally produced building materials and techniques that they can afford and manage.

Technical briefs are documents produced by Practical Action which are freely available...

A Year Ten module from the Salters’ double award science course. A surveyor’s report on a proposed barn conversion is used to introduce different materials used in construction and issues associated with their use. The lessons which follow then consider each type of...
