Young scholars research the evidence for prehistorically formed methane hydrates contributing to global warming. In this climate change lesson, students work in groups to research methane hydrates, global warming, The Cambrian Explosion, and The Paleocene Extinction. They present the results of their research and discuss how the topics are related.
Using meters as years, your class works together to map out the geologic time scale on a football field. Plenty of background information is included in this lesson plan as well as several resource links and a student worksheet. Your earth science class will score a touchdown in understanding geologic history!
Students describe the overall events that occurred during the Paleocene extinction event as well as the processes that are believed to result in global warming after group research. They infer how a global warming event could have contributed to the Paleocene extinction event.
Cartoon children compare the earth's age to timescales that we understand:a calendar year, the thickness of a book, the human lifespan. This smart film clip is definitely worth adding to your geologic timescale lesson! If you subscribe to the free membership on the publisher's website, you will also have access to comprehension and discussion questions, as well as links to other related resources.
Three eras of the current Phanerozoic geological eon are broken down for your pupils. Biological features of the Paleozoic, Mesozoic, and Cenozoic eras are listed, along with the possible causes of mass extinctions. Plenty of diagrams, charts, graphs, photos of fossils, and drawings of prehistoric organisms accompany the text.
Twenty-seven slides will give your students a complete overview of the biological and chemical theories behind the development of life on Earth. There are fabulous real life photos and labelled diagrams to give details about the first eukaryotes, and explosions of diversity in history. Students could use this PowerPoint in an independent study or as a source of information for research.
This sequence of slides presents information about the hypothesis of key events in the Origin of Life. The conditions on early earth are given and the process that would allow for living organisms to develop. The evidence will stimulate discussion in your class and your students may be interested in continuing research on their own. This slideshow stands on its own, so with basic prior knowledge your class could use this in personal study time.
