Understanding Geologic Time introduces students to geologic time, the evidence for events in Earth’s history, relative and absolute dating techniques, and the significance of the geologic time scale.

Stories From the Fossil Record provides students with a basic understanding of how fossils can be used to interpret the past. provides an introduction to cladistics (a way of organizing living things by common ancestry and evolutionary relationships) and involves students in posing hypotheses about past life based upon evolutionary history.

Scientists use radiometric dating to determine the relative age of a new fossil. Scientists use relative dating to determine the absolute age of a new fossil. Scientists use radioactive isotopes to determine the absolute age of a new fossil. Scientists use index fossils to determine the specific years of age of a new fossil.

Former creationist Glenn Morton examines several famous young-earth creationist arguments and provides data to illustrate their flaws. The I found it odd that nowhere in the book was it indicated where Woodmorappe earned his degrees or his current professional affiliation (Where does he teach science? I believe that it's reasonable, when evaluating what purports to be a scientific paper, to inquire as to the author's expertise to write about the subject -- especially when the relevant information given is so vague. degree in geology from a secular university with which he's still affiliated and has published a couple of papers in mainstream geologic journals under his real name.

Now select the mean life time of the nuclei with the slider, press the START button, and watch them decay away as a function of time (displayed in the upper right corner).

Shown also is a histogram (in green) of the number of nuclei remaining at a given time.

The Arthropod Story takes students on an interactive tour through the amazing evolutionary history of arthropods, introducing them to taxonomy, paleontology, natural history and principles of evolution.

The Evolution of Flight examines evidence from the fossil record, behavior, biomechanics and cladistic analysis to interpret the sequence of events that led to flight in the dinosaur lineage.Students gather, organize and analyze data and then propose hypotheses about the evolution of flight in birds.A series of interactive modules that explore the history of life on Earth, while focusing on the processes of science.Each module contains suggested lesson plans and an extensive teacher’s guide.There are four different pathways to explore: biodiversity, geologic time, paleoecology and past lives. Adventures at Dry Creek virtually engages students in scientific research.

Students join “science mentors” to gather data and interpret direct and indirect evidence to propose multiple hypotheses of what life was like in Montana 60–70 million years ago.
