Air pollutants arise from natural processes and human activities. In this SATIS Revisited resource, students investigate air pollution, how it is monitored and some effects on human health. Air pollutants arise from a wide variety of sources, although they are mainly a result of the combustion process. It is easy...

In this topic, from the Association for Science Education (ASE), students explore the importance of biodiversity to humankind. The topic is designed to allow classes in schools across the world to exchange information about the factors affecting biodiversity today.

Students focus in particular on the...

This SATIS Revisited resource looks at the environmental and ecological consequences of further expansion of biofuel crops due to deforestation, biodiversity and landscapes.

Biodiesel is a fuel derived from biomass (...

In this SATIS Revisited resource students consider the factors that contribute to the greenhouse effect, the possible effects of global warming, and how they as individuals are contributing to carbon dioxide emissions.

Climate change is affecting the natural world. The distribution of some species appears to...

This video introduces a reliable technique to demonstrate tissue culture and totipotency, and shows how best to use this protocol with your students.

Unlike animal cells, many plant cells are totipotent, meaning that...

In this ARKive activity, students research and design their own conservation programme to learn about the importance of biodiversity as well as the economic benefits and services ecosystems provide. Using examples of successful conservation programmes within the UK Overseas Territories, students learn about the...

This resource provides background information for students about the structure of DNA, DNA replication, genetic engineering, cloning, genetic testing and DNA fingerprinting.

The activities for students include a practical activity where students extract their own DNA from cheek epithelial cells or plant...

In this SATIS Revisited resource, students consider the Californian Gold Rush and its impact on the environment through pollution in the food chain and analysis of mercury in fish from local lakes and rivers.

This...

One of a series of resources from Science & Plants for Schools (SAPS) investigating key topics in plant biology. An enjoyable and thought-provoking introduction to the topic of sexual reproduction in plants. Students observe in real time the growth of a pollen tube, over the course of a lesson. When a pollen...

In this SATIS Revisited resource students use real data to determine the cause of illness in cattle on a farm. They analyse the animals' diets to find that the illness is caused by mineral deficiency.

This unit has...

One of a series of resources from Science & Plants for Schools (SAPS) investigating key topics in plant biology. An enjoyable and reliable practical activity allowing students to compare factors affecting photosynthesis. Possible investigations could include the rate of photosynthesis in sun and shade plants,...

One of a series of resources from Science & Plants for Schools (SAPS) investigating key topics in plant biology. An intriguing way to demonstrate gravitropism in action over the course of a lesson. Using black film canisters, a freshly cut seedling stalk (hypocotyl...

One of a series of resources from Science & Plants for Schools (SAPS) investigating key topics in plant biology. In this practical activity, students to investigate the role of light in starch production in leaves during the process of photosynthesis. By using leaf discs rather than whole leaves, a number of...
