SC.912.L.15.8

Students will develop a scientific explanation for the origin of life on Earth and present the information that they find to the class through song, rap, story-telling, play-acting, or another creative method approved by the instructor.

Type: Lesson Plan

In this lesson, students will analyze an informational text that addresses a new method of producing polypeptides from only amino and hydroxy acids, with no biological catalysts necessary. Researchers at Georgia Tech have been able to produce polypeptides by subjecting amino and hydroxy acids through a wet and dry cycle. This allows for prebiotic molecules to be formed on land, without large amounts of water or extreme boiling temperatures. This method also allows for the breakdown and reassembly of organic materials to form random sequences that could lead to the variation needed for life. This lesson plan is intended to support reading in the content area; it includes a note-taking guide, text-dependent questions, a writing prompt, answer keys, and a writing rubric. 

Type: Lesson Plan

This toolkit supports the development of an instructional unit on diversity and evolution and aligns with academic standards for science, English language arts, and mathematics for students in grades 9-12. The elements of this toolkit were assembled based upon their suitability for constructing a multi-day instructional unit on hominid evolution that corresponds with the 5E Learning Cycle of engage, explore, explain, elaborate, and evaluate. Your task as a lesson study team is to analyze the materials that are included in this toolkit and evaluate how they can be incorporated in a 5-E instructional unit plan that complies with the academic standards for science, English language arts, and mathematics. As you study these resources it is important to make note of any deficiencies or gaps that will need to be addressed and make modifications in the lesson resources and activities where needed.

Type: Lesson Study Resource Kit

This lesson study resource kit is designed to support lesson study teams in developing a unit of instruction for students in grades 9-12 on the topic of diversity and evolution.

Type: Lesson Study Resource Kit

Learn how to identify and describe the leading scientific explanations of the origin of life on Earth.

Type: Original Student Tutorial

This text resource is designed to support reading in the content area. The article describes how researchers at Georgia Tech have discovered that polypeptides, which are the main component of proteins, can be formed by mixing amino and hydroxyl acids, and then simply putting them through wet and dry cycles. This would be a more plausible way for early prebiotic molecules to form. Previously, the only way to produce polypeptides involved boiling temperatures, which are not conducive to life.

Type: Text Resource

This informational text resource is intended to support reading in the content area. Scientists have formulated and tested another theory to explain how life began on Earth: meteorites crashing into the surface of the ancient planet brought with them the elements of life's building blocks. The results of the scientists' simulations are promising.

The theory of endosymbiosis suggests that mitochondria and chloroplasts were once free-living, small prokaryotes that were taken up by larger prokaryotes. It also describes how a large host cell and ingested bacteria could easily become dependent on one another for survival, resulting in a permanent relationship. This tutorial will help the learners to understand the process of endosymbiosis.
