Using Carbon Isotopes in Astrobiology: Origin of Life and beyond part of Teaching Activities
Phoebe Cohen, Williams College
Carbon isotopes are used in many different ways by scientists to reconstruct Earth's past. For example, we can use carbon isotopes to determine when life first evolved on Earth, and to learn more about what ...

Stable Isotopes and M&Ms part of Oceanography:Activities
Roman de Jesus, Fullerton College
Students are often confused by the concepts of stable isotope signatures and conventional notation. This activity is designed to introduce students to the del notation (isotopic signature), fractionation, and end ...

Sediments and the Global Carbon Cycle part of Sedimentary Geology:Activities
Lonnie Leithold, North Carolina State University
This is a series of exercises designed to introduce undergraduate students to the role of sediments and sedimentary rocks in the global carbon cycle and the use of stable carbon isotopes to reconstruct ancient ...

Teaching Stable Isotope Geochemistry in an Undergraduate Petrology or Geochemistry Course part of Petrology:Teaching Examples
Steve Dunn
This assignment includes three reading assignments for students that (1) introduce the basics of stable isotope geochemistry, (2) explain carbon and oxygen isotopic shifts that result from volatilization and/or ...

Isotopes in the Hydrogeologic System part of Hydrogeology:Hydrogeology, Soils, Geochemistry 2013:Activities
Laura Ruhl, University of Arkansas at Little Rock
The students will use activities to understand atomic mass and isotopes and stable isotopic fractionation in the hydrologic system.

Batch and Rayleigh Decarbonation Modeling of d13C part of Petrology:Teaching Examples
Jade Star Lackey, Pomona College
This is an Excel spreadsheet and graph that illustrates standard "batch" and Rayleigh decarbonation models and how they can be used to detect fluid infiltration during metamorphism of carbonates. It makes ...
