A poster from the 2012 Holiday Lectures on Science, Changing Planet: Past, Present, Future. It details the importance of foraminifera, known as "forams" for short, in discovering significant changes in Earth's past.
A poster from the 2012 Holiday Lectures on Science, Changing Planet: Past, Present, Future. It shows the different organisms and metabolic diversity that results in a miniature model called a Winogradsky column.
The poster from the 2011 Holiday Lectures on Science, Bones, Stones and Genes: The Origin of Modern Humans. It provides a unique look at the classic "tree of life" and features a timeline of various hominid fossils and their stone tool usage.
The poster from the 2010 Holiday Lectures, Viral Outbreak: The Science of Emerging Disease, illustrating the size, geometry, and different classifications of viruses.
This activity supports the film The Origin of Species: Lizards in an Evolutionary Tree. Students are guided to sort the lizard species by appearance, then generate a phylogenetic tree using the lizards’ DNA sequences to evaluate whether species that appear similar are closely related...
This classroom experiment supports the film The Origin of Species: The Beak of the Finch. Students collect and analyze data to learn why even slight variations in beak size can make the difference between life and death.
Discover the environmental factors that caused the five big mass extinctions in Earth’s history and which species they impacted.
