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 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.
This interactive module examines Earth’s past and present climate, highlighting the effects of two important factors: solar radiation and the composition of the atmosphere.
This interactive, modular lab explores how stickleback fish and fossil specimens are used to study evolutionary processes, with an emphasis on data collection and analysis.
This tutorial describes how bacteria communicate by a process known as quorum sensing, as shown through a series of experiments involving genetically engineered bioluminescent bacteria.
