Teaching Tips | Science | Pedagogy |
- Video could be watched as a stand-alone or in association with the two other videos on the Sea Change website ( Part 1: In the Field, and Part 3: Interpreting the Results)
- Particularly strong for chemistry classes.
About the Science
- Video follows the research of Dr. Raymo and other scientists' use of fossil shell samples from Australia to study how Earth responded to higher air temperatures in the Pliocene era.
- Scientist Jeremy Inglis demonstrates and explains how relative proportions of isotopes of strontium can be used to date the fossil shells in which they are found.
- Comments from expert scientist: The video is very well done, well-paced and makes use of very good graphics and animations.
About the Pedagogy
- Familiarity with high-school level chemistry will help students understand the mechanism and power of tools such as thermo isotope mass spectrometers (TIMS) to date geologic samples.
Technical Details/Ease of Use
- Video can also be viewed on the Sea Change website: http://sealevelstudy.org
- Can be viewed in HD.
- Closed-captioning provided; however, when captions are turned on the words are inaccurately transcribed and inserted incorrectly, which may be distracting to viewer and students.

Disciplinary Core Ideas: 5
HS-ESS2.D1:The foundation for Earth’s global climate systems is the electromagnetic radiation from the sun, as well as its reflection, absorption, storage, and redistribution among the atmosphere, ocean, and land systems, and this energy’s re-radiation into space.
HS-ESS2.D2:Gradual atmospheric changes were due to plants and other organisms that captured carbon dioxide and released oxygen.
HS-ESS2.D3:Changes in the atmosphere due to human activity have increased carbon dioxide concentrations and thus affect climate.
HS-ESS2.D4:Current models predict that, although future regional climate changes will be complex and varied, average global temperatures will continue to rise. The outcomes predicted by global climate models strongly depend on the amounts of human-generated greenhouse gases added to the atmosphere each year and by the ways in which these gases are absorbed by the ocean and biosphere.
HS-PS1.B2:In many situations, a dynamic and condition-dependent balance between a reaction and the reverse reaction determines the numbers of all types of molecules present.
