Today you took your Investigations in Space Science semester B exam which will count as 20% of your 4th quarter grade. Good luck with the rest of your exams. If you have any missing/corrected work, please get it in as soon as possible.
Today’s objective was to review concepts from plate tectonics, earth materials and earth’s history to prepare for the final exam. You spent the first half of the period going through your answers to the study questions 11-12. Then you walked around the room to check your work using study questions 11-12 key. Finally you discussed the 3 BCRs from the Modified IESS B Review June 2012 for your exam tomorrow.
Today’s objective was to compare the temperature and climate changes in the more present past with millions of years ago. We started the lesson going over inclusions and intrusions in page 3 of relative warm up. Then you were given you grade sheets and went through your work for any missing or corrected assignments yo could turn in. We then reviewed geologic timelines and dinosaurs with Tim and Moby (sligoms, brainpop). Then we talked about the periodic cycles of cooling and warming of the Earth with Greatest Discoveries: Periodic Ice Age (danafarrellschneider, student) and Tell me why mass extinction and the possible causes of mass extinction. Finally we worked on identifying the causes and effects of global warming with Intro Global Warming. Remember that your final exam review is due June 5th and your exam is June 6th.
Today you worked on Geologic Time and Mass Extinction using the Earth’s Changing Surfaces textbook.
Today’s objective was to compare how scientists date rocks using relative dating and absolute dating. We started the lesson with page 2 of relative warm up. Then we discussed the formation of inclusions and unconformities using this animation: Observe an animation showing the formation of an unconformity. Then we moved on to researching ways scientists age rocks using the Earth’s Changing Surface textbook and Is it ALL Relative or Absolute .
Today’s objective was to compare the process of radioactive dating to the process of relative dating. We started the lesson with page 1 of the relative warm up. Then we worked on finishing your Fossils Application BCR (page 4). Then you worked on completing the determining Geologic Age: Relative Dating assignment. We then discussed the concept of half-life and how radioactive materials have a half-life and that this rate of decay can be used to determine the age of rock samples. We then looked at 100 Greatest Discoveries: Radioactive Dating. We will investigate this and other methods of absolute dating on Tuesday.
Good afternoon. Today’s objective was to explain laws and principles of relative dating and its use for age determination is explored. We started the lesson going over the multiple choice questions on Fossils Application. You were then told that the Fossil BCR (page 4 of Fossils Application) is due tomorrow. We then went on a fossil hunt to compare the age of fossil found in different layers of rock. We then collected information using Relative Age of Rocks Notes Key. We then used these notes and the Earth’s Changing Surface textbook to complete Determining Geologic Age: Relative Dating.
Good afternoon. Today’s objective was to compare and contrast the 6 main types of fossils and explain how scientists use fossil evidence. We started by going over the IESS B Exam Review June 2012. This exam will cover tectonic activity, earth materials, and earth history. Use this guide along with your unit assessment reviews to help you prepare. You exam will be June 6. Then we took a look at a video of an whale fossil found by masons in Italy from National Geographic and took notes using Fossils Application. Then you used your Earth’s Changing Surfaces textbook to complete the rest of the assignment. your BCR is due on Friday, May 25th.
Today you started the last unit, Earth’s History. You worked on describing fossils using fossils, the reading is attached.
Today’s objective was to describe how the Earth’s surface is constantly changing and reforming. We spent the class taking the county assessment. We will move onto Earth’s History tomorrow.
