the geological time scale
The document summarizes the geological time scale from the Pre-Cambrian era to the present. It divides geological history into eons, eras, periods, and epochs. The Pre-Cambrian era spanned from 4600 million years ago to the start of the Cambrian period 540 million years ago. Major periods described include the Cambrian when life exploded, the Devonian which was the age of fish, and the Cretaceous when flowering plants first appeared. The Mesozoic era was the age of reptiles including dinosaurs. The Cenozoic era is the age of mammals, including the first horses and modern humans.
The geological time scale
Arthur Holmes was a British geologist who made two major contributions to geology. He pioneered the use of radioactive dating of minerals, which allowed scientists to accurately date geological formations. He also grasped the implications of mantle convection and plate tectonics. The geological time scale is a system that relates the layers of rock in the Earth's crust to periods of time in Earth's history. It is based on events that occurred during each period, geological evidence like mountain building and erosion, and fossil evidence found within the different rock layers.
Stratigraphy and history of earth
This document discusses stratigraphy and related geological concepts. It begins by outlining the contents of stratigraphy, including principles of sequence stratigraphy, sedimentary basins, models in sedimentary geology, and applied sedimentary geology. It then discusses key stratigraphic concepts like lithostratigraphy, chronostratigraphy, and biostratigraphy. Finally, it covers principles of correlation, criteria for stratigraphic classification, and elements of correlation like time units, rock units, and correlation methods involving lithological, biostratigraphic, and radioactive dating controls.
The geological time scale
The geological time scale records 4.6 billion years of Earth's history divided into eras, periods, and epochs based on studying rock layers and fossils. It begins with the Precambrian era which covers 88% of Earth's history. The timescale includes the Paleozoic era of ancient life dominated by invertebrates like trilobites; the Mesozoic era of middle life dominated by dinosaurs and the breakup of Pangaea; and the ongoing Cenozoic era of recent life dominated by mammals including the evolution of humans.

The Southern Central Divide Blended Learning Project aimed to integrate new technologies to empower learning and transform leadership across 30 secondary and area schools with over 11,000 learners. The project provided professional development to one teacher from each school on using tools like Moodle, Educo, and ePortfolios to enhance student-centered learning. Teachers discussed using technologies like virtual field trips, email, Skype, and online research to support student-led units and increase computer skills, with goals of expanding use of these tools school-wide.

Introduction to Karitane
Karitane is a unique 2-4 km beach located 50km north of Dunedin that has many coastal landforms formed by geological and coastal processes. The peninsula contains volcanic and sedimentary rocks and features such as mother-child rock stacks formed from collapsed sea caves, blowholes formed from collapsed sea caves below the waterline, and a sand spit formed by longshore drift. The sedimentary cliffs show layered deposits that were uplifted over time.

Karitane is a unique 2-4 km beach located 50km north of Dunedin that has many coastal landforms formed by geological and coastal processes. The peninsula contains volcanic and sedimentary rocks and features such as mother-child rock stacks formed from collapsed sea caves, arches formed from eroded blowholes, and a sand spit formed by longshore drift. Observation of these landforms and features helps explain the coastal geological processes that created each one.

The document compares disparities between rural and urban areas in Tanzania. In rural areas, only 1% of roads are paved, most people lack access to safe water and electricity, and primary education is the highest level achieved for most. In contrast, urban areas have 45% paved roads, over 60% access to electricity, and 17% attain secondary education or higher. Overall, the urban standard of living is significantly higher than in rural villages with fewer opportunities and resources.

There are many disparities between men and women in Tanzania. Traditionally, boys are valued more in society and perceived as able to earn income, while girls are expected to take on domestic duties and care for the family. As a result, boys are more likely to receive an education, with male secondary school attendance at 8% compared to 3% for females. Fewer women also attend university. While the situation is improving with more girls attending primary school, significant disparities remain in many areas of Tanzanian society such as health, employment opportunities, marriage practices, and land ownership.

The document discusses HIV and AIDS, providing information on:
1. What HIV and AIDS are and how they are transmitted between people.
2. The global and local impact of the HIV/AIDS pandemic, including statistics on infection rates and numbers of deaths.
3. The effects of HIV/AIDS on communities, including impacts on healthcare systems, education, orphaned children and food security.
4. Strategies for preventing the spread of HIV, caring for infected individuals, and supporting children and families affected by the disease.
Pd session 1_group_a_and_b_23_march_2011
The document outlines the topics and activities to be covered in a series of fortnightly professional development sessions for teachers. The first session will introduce GEALI and comprehension strategies used by good readers. Teachers will learn about activating prior knowledge through a DVD and anticipatory guide strategy. They will also explore vocabulary teaching approaches and be given resources on teaching as inquiry. Handouts on structured vocabulary organizers and prior knowledge strategies from books by Sheena Cameron will be provided to use before the next session.
