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.
