The return of beavers to the British countryside is boosting biodiversity, reducing storm-induced flooding, and restoring wilderness to an over- manicured landscape.
In this activity, students engage with an example from the Serengeti ecosystem to illustrate the exchange of nutrients between plants, animals, and the environment.
This activity explores images of planarians regenerating missing body parts, which serve as phenomena for learning about cell division and differentiation.
This interactive module allows students and educators to build models that explain how the Earth system works. The Click & Learn can be used to show how Earth is affected by human activities and natural phenomena.
This interactive module consists of a virtual Winogradsky column, which can be used to explore the diversity of microbes, microbial metabolic strategies, and geochemical gradients found in sediments.
This interactive module explores how mutations arise in germline and somatic cells. It also shows how these mutations can lead to genetic conditions, such as cystic fibrosis and cancer.
This interactive module explores the phases, checkpoints, and protein regulators of the cell cycle. The module also shows how mutations in genes that encode cell cycle regulators can lead to the development of cancer.
