This activity leads students through derivations of the equations associated with radiometric dating: the radioactive decay equation, the half-life equation and the age equation. After the equations have been derived, students are asked to apply them to geologic applications. This activity is appropriate for lower division undergraduates. Learning goals, context for use, teaching tips, materials, assessment tips and related resources are provided.
Temperature Profiles in Permafrost
In this STELLA modeling exercise, students create a model of heat flow in the outer kilometer of Earth's crust. Then they perform experiments to change the air temperature variable in an attempt to replicate the findings of Lachenbruch and Marshall (1986) who used inflections in the geothermal gradient of Alaskan permafrost to search for evidence of recent climatic change. Learning goals, context for use, teaching tips, materials, assessment tips and related resources are provided.

Symbols of Power in Clothing Worn by the Plains Indians
Power shirts, often made of tanned animal hides and adorned with objects such as fur, beads, and locks of hair, were highly important in the culture of many Native Americans. These shirts, which were associated very closely with the identity of their wearer, contained various symbols representing success in war, spirituality, special abilities, and outstanding achievements. After studying these shirts, learning to understand their significance to Native Americans, and discussing the symbols they
Tip-enhanced Raman spectroscopy
2D cut of complete 3D simulations of gold tip and gold surface (tip-to-surface distance is 10 nm) excited by a laser pulse at 652 nm. Laser pulse propagates towards the screen and is polarized along tip's longer axis. Intensity is plotted in logarithmic scale and is normalized to it's maximum. Maximum ...
The Open Movement and Libraries
"Openness" which has become a hallmark of the new Web has long been a mission in libraries. The philosophy of free and open access to information and technology has become a critical subject for information and technology leaders and practitioners. This course will explore the role and participation of library science and librarians in this movement. This course will give an overview of open-source technologies (such as content management systems and ILS programs) which are being used by librari
Chemicals, the Environment, and You
provides lessons for learning about the relationship between chemicals in the environment and human health. Topics include the science of toxicology, dose-response relationships, individual susceptibility, risk assessment, and environmental hazards. Students are introduced to the ever-changing nature of our understanding of how chemicals influence the health of living organisms.
NASA KSNN What is gravity?
Gravity is one of the fundamental forces of nature. No one really understands exactly why, but gravity is a force that pulls objects toward each other. The mass of the objects and distance between the objects affects the strength of the force of gravity. Greater masses attract with more force and the force weakens as the objects get further apart.
NASA KSNN Why is it important to estimate?
Learning how to estimate is a valuable skill. Estimating helps you plan ahead and check your work to see if your answers make sense
