Provide your students with a quality review on the history of life on Earth and the origins of life. The key to success in teaching a unit on any topic is to provide the best instruction possible followed by a good review exercise.
This PowerPoint consists of 92 slides of questions and answers and provides an excellent review for the chapter test. I use this review PowerPoint after completing the material in this unit: The History of Life on Earth PowerPoint with Notes for Teacher and Student.
This is NOT a teaching PowerPoint. It is strictly for review purposes. Each slide has one question followed by one answer.
The questions are of varying difficulty levels. Many of the questions are basic and concrete in nature, but many of the questions involve critical thinking and problem solving skills.
This set of questions is perfect for any type of game format. Students can form groups and compete with one another during the review exercise. The review PowerPoint can also be used in a computer lab with each student reviewing independently and silently.
This review PowerPoint is appropriate for any biology or life science class with students in grades 9 - 12.
Topics covered by this lesson:
1. Early Ideas About the Origin of Life: Biogenesis, spontaneous generation, abiogenesis, the experiments of Redi, Spallanzani, and Louis Pasteur.
2. Earth’s History: The age of the Earth, radioactive dating, isotopes, radioactive isotopes, carbon-14 dating, the limits of carbon-14 dating, the dating of older rocks and fossils, the chemical and physical processes that might have occurred that led to the first life forms.
3. The First Organic Compounds on Earth: The Oparin hypothesis, the experimental evidence of Miller and Urey, examination of new evidence about the atmosphere of early Earth.
4. From Molecules to Cell-Like Structures: Microspheres, coacervates, the experiments of Sydney Fox, the life like properties of microspheres and coacervates.
5. The First Life Forms: Key processes of metabolism and replication, protobionts.
6. The Origin of Heredity: RNA as the first genetic material, ribozyme, the ability to self-replicate, the role of natural selection.
7. The Fossil Record: The fossil record shows change over time, why the fossil record is incomplete, types of organisms that do and do not form fossils.
8. The First Single Celled Organisms: The anaerobic conditions on early Earth, first heterotrophic prokaryotes, rise of autotrophs, chemosynthesis, archaebacteria.
9. Photosynthesis and Aerobic Respiration: The production of organic compounds in photosynthesis, the release of oxygen into the atmosphere, the damaging nature of oxygen, the evolution of aerobic respiration, cyanobacteria, production of ozone.
