Chameleon bubbles are formed when a sodium alginate solution is dropped into a calcium chloride solution.  The bubbles are filled by an acid‐base indicator solution; so, adding the beads to acids or bases leads to colour changes inside the bubbles by diffusion and pH change. Students can learn about acids, bases,...

A pair of videos that investigates the Ohm’s law relationship. The first allows students to carry out an experiment on the IV characteristics of a wire (Ohm's law) from home. This is a required practical for students to understand and be able to carry out for GCSE Combined Science and Physics.  The second explains...

A short video that demonstrates how to investigate the charge of different insulators due to friction.  

In this activity, students look at cheek cells under a microscope to identify basic cell structures.  It allows students to practice their microscope skills, making a slide, staining a sample and making observations.

Chemical equilibrium acids and bases is one of the titles in the series of ASE Lab Books that were published in the early 1970s for the Association for Science Education by John Murray. Each title covered one or two topics and brought together the best of the teaching...

The chemical garden is a well‐established experiment from the chemistry of salts, solubility, diffusion, and solutions. The nice thing is that if metal salts are put in sodium water glass solution, it can lead to an effect reminiscent of plants growing. This growing process can be observed and analysed. In the end...

A balance is set up with two pieces of iron wool. One piece is set alight: it appears to be getting smaller but, mysteriously, the balance tips the other way.

Curriculum links include chemical...

These We Are Aliens! related chemistry activities for the class room, have been devised by devised by Steve Althorpe and Judith Green. The resources include games, practical activities and worksheets. Supporting videos demonstrate the activities. The following curriculum areas are covered:

• depression...

From Solar Spark, this activity allows students to see how chlorophyll can be energised and how this causes it to fluoresce. Chlorophyll in plant leaves absorb red light and pass the energy on to other parts of the plant, hence leaves look green. But if there is nowhere for the energy to go, it gets released as...

Chromatography is one of the titles in the series of ASE Lab Books that were published in the early 1970s for the Association for Science Education by John Murray. Each title covered one or two topics and brought together the best of the teaching notes and experimental...

This resource provides a range of indoor and outdoor practical activities, suitable for students across the primary phase. Activities are designed to help children identify and name a variety of common plants and animals and link to work on minibeasts, habitats and classification. Many of the activities are cross-...

Produced by The Centre for Industry Education Collaboration (CIEC), in these activities, students investigate the cleaning power of washing agents and through a series of investigations that include:

* Which washing agent works best at low temperatures?
* Which washing agent produces the most foam?...

This resource can be used when teaching about the weather and environment. It contains four activities which are:

* Measuring contrails in the sky
* Measuring wind direction at cloud height
* Using bubbles to measure wind direction at our height
* Answering questions about how hot or cold...
