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,...

Work done in this Nuffield 13 - 16 module followed from the B unit called ‘Senses’. This X unit provided enough material for eight double periods. It could be selected to complete either a Science or a Further Science course. The teachers’ guide included three...

This resource pack from Association for the Study of Animal Behaviour (ASAB) focuses on the role of judgment in animal behaviour studies. It consists of:

*background information for teachers

* images of Canada goose goslings at various stages of development and images of seven of the behaviours of...

This colourful leaflet from the Natural Environment Research Council (NERC) looks at how environmental factors have affected human evolution. It includes a timeline and map showing how and where humans have developed and changed over millions of years.

Humans are a truly global species. We have colonised...

Changing Futures was a project that brought together teenagers with cystic fibrosis (CF), clinicians, artists, scientists and educationalists, to develop resources exploring gene therapy and CF. Run by Nowgen and with the support of the Wellcome Trust, the collaboration put young people with CF at the centre of...

Produced by Nowgen and the Wellcome Trust, the Changing Futures materials help students to understand the causes, effects and treatments of cystic fibrosis (CF). This is one of the most common genetic conditions in the UK.

The project team included young people with CF, artists, scientists and people working...

The Changing Futures project looked at cystic fibrosis from a range of perspectives. Produced by Nowgen and supported by the Wellcome Trust, the resources in this collection look at gene therapy, its development and future prospects as a treatment for cystic fibrosis (CF).

The materials are in the form of...

The Science upd8 activity introduces the concept of validity in the design of scientific experiments. Based on the card game 'Cheat', the scenario is a scientific conference where scientists are learning about, and criticising, each others' work. Students have a series of cards which contain different claims and...

The Chilled Food Association (CFA) was formed in 1989 to establish, continuously improve and promote best hygienic practice standards in the production of retailed chilled prepared food. CFA represents many of the leading names in UK chilled prepared food production, predominantly supplying the retail trade.

From the Chilled Food Association (CFA), these activities are aimed at Key Stage Four students and look at a range of topics that include: * Common bacteria that cause food spoilage * Reducing the risks of bacterial contamination * Food hygiene * Food and taste * Developing a new food product * Work in the chilled...

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...

Cholera is an infectious disease caused by the bacterium Vibrio cholerae. There have been seven worldwide disease outbreaks or pandemics since 1817, killing millions of people and infecting millions more. This resource, from the Microbiology Society, charts the history of the disease and investigates the causes,...

This Catalyst article looks at how an internal biological clock within every cell of the human body helps to co-ordinate and organise human behaviour and metabolism into approximately 24-hour rhythms – allowing organisms to synchronise with, and anticipate, day and night. When the body clock is disrupted in humans...

The Citizen Science project was a collaboration between @Bristol's Education team, the University of Bristol, teachers and scientists. Funded by the Wellcome Trust, a series of activities engage both teachers and students in discussions about biomedical science.

This collection contains a range of teacher...
