Introduction to Lowland Heathlands

This resource is an interactive activity which aims to provide an introduction to the lowland heathland habitat. The five topics relating to lowland heathlands covered by the resources include: • The biotic components of lowland heathlands, focusing on plants • The biotic components of lowland heathlands, focusing...

Ecological Survey

Using the context of land remediation, this resource describes a series of investigations to measure the distribution of plants and animals, including a range of sampling techniques and the measurement of abiotic factors such as soil conditions, temperature and light intensity.  These activities are generally...

Designing Investigations

This resource, from the University of Nottingham, describes a number of investigations which could be carried out in heathland habitats. Heathlands are excellent habitats to use for designing and carrying out experiments. Plants are often relatively easy to identify when compared with other habitats and...

Arctic sea ice and climate change

This resource from the European Space Agency climate change resource pack provides background information on the role of Arctic sea ice upon the Earth’s climate system. All activities are set in the context of the Northwest Passage. Changes in the amount of sea ice can disrupt normal ocean circulation, leading to...

Debate kit - stem cells

This kit encourages students to consider the ethical issues that stem cell treatments raise and to develop students’ debating and discussion skills. Role play gives students a chance to explore the different sides of the issue and compare others’ points of view, as well as considering social, ethical, political and...

Hope Beyond Hype

It is long journey from basic stem cell research to a reliable stem cell therapy. This comic book explores the role of stem cell researchers and the process they undertake as they try to move stem cell research on towards clinical trials and therapies. A selection of card games is provided which can be used to...

Model Cells

The cell is the smallest unit of life and for many millennia single celled organisms were the only form of life on Earth. It’s this type of life that astrobiologists are looking for elsewhere in the solar system. In this activity, wallpaper paste is used to build model cells Curriculum areas covered: • Cell biology...

Tackling Tropisms: Gravitropism and Phototropism

This set of demonstrations into the effects of tropisms on seedlings is both simple and extendable. Seeds sown on damp cotton wool in Petri dishes are grown either flat, or stuck vertically to a wall, showing the different effects of gravitropism. After a week, students...

Algal Balls - Photosynthesis Using Algae Wrapped in Jelly Balls

This reliable practical allows students to use algae to look at the rate of photosynthesis with quantifiable and replicable results. In this protocol, the green alga Scenedesmus quadricauda is immobilised in alginate beads. Changes in the colour of hydrogen carbonate indicator solution (also called...
