Many abandoned quarries are found in the park that mostly exploited chert and basalt rock for aggregate building materials. Some links are provided below. In addition to the San Andreas, there are many smaller subsidiary faults in the area including the dangerous Hayward Fault to the east of the park. In this activity, you will learn more about an ancient environment through your Web research. You will create a journal entry of a specific geologic time period for planet Earth. Discuss the implications of the environmental crisis as it exists in the context of Earth history.
Day 2-3: Students will have computers with internet access to research an organism of their choice and trace it back through the geologic time to its most basic relative. Ask students questions about how old the earth is and when did life first appear on Earth? No metaphor is too silly, as long as your math is correct and your choice has meaning to you. Students will be able to explain and diagram the divisions of time in the history of life on Earth. It's older than your parents, or your grandparents, or even you great grandparents! Younger rocks in the park are linked to sea level rise and fall during past glacial periods. Students may bring up the Flintstones or the Jurassic Park, Ice Age, or the Land Before Time. This active tectonism is responsible for the rugged terrain around the Bay and in Golden Gate.
How old are you today? Students should have prior experience with thinking maps, specifically brace maps. Ask students to take a few minutes to review the chart before asking questions. Since we are using a distance metaphor as an example here, a football field with a length of 100 yards will do just fine. Concepts covered in this lesson, including geologic history, age dating, plate tectonics, timelines, and fossils are prerequisite concepts for understanding the theory of evolution, which is another topic taught at this grade level. Thousands of teachers win these grants every year. Students use paleogeographic maps to discuss both historic and prehistoric changes to the landscape.
The teacher may provide links to the websites to save time and to ensure quality research. I then give out 16 clothes pins and ask various students to put a cloths pin on the 'time line' at various 'geologic events'. A pie chart is used to compare the different parts that make up a whole amount. Geology classes frequently visit chert outcrops to study their dramatically contorted beds, which are evidence of extreme tectonic pressures developed in a subduction zone. Highest mountain, deepest lake, biggest tsunami and more.
Earth Science is all around you How old are the rocks in your state? This lesson introduces the geologic time scale and the concept of time segments being divided by major events in Earth's history. Articles about geysers, maars, deltas, rifts, salt domes, water, and much more! Using careful analogies and written historical records, the authors help students understand the development of the geologic time scale, including how this depended on gathering evidence and making comparisons. It is even older than the hills, valleys, and rivers around where you live. Students will likely have been introduced to the geologic time scale in earlier grades, so this lesson is structured loosely to enable you to adapt the content to match the levels and needs of your particular students. Say, did you ever wonder about all of the things that have ever happened on Earth and how old it really is? Determining the location of the other important dates in the history of the Earth is up to you. Other students may be able to estimate the size of each section on the pie chart without using the protractor. Example: The method used to determine a metaphor value true-to-scale will be similar for all metaphors.
Eras are the next largest categories represented here. On day 2, students research an organism of their choice and trace it back to their most basic relative. Each hour represents approximately 375 million years. Geoscientists Invite a paleontologist to discuss our geologic history. Students will be provided with a rubric that will guide them while they work on the final product.
These rocks belong to the Franciscan Complex and were greatly deformed and partly metamorphosed as the ocean floor was thrust under the western edge of the North American Plate, resulting in a landscape of easily eroded, sheared and crushed sandstone and shale, with occasional blocks of more resistant rocks like chert that form prominent outcrops. If you need help, see below for an example. Do you want to know and how geologic time periods were determined? Periods are relatively shorter in time length. All necessary materials are technically correct but additional materials are necessary to make this activity engaging and effective for non-expert teacher use. How old is that, really? Some of the worksheets displayed are Work the geological time scale, Geological timeline activity, Geologic time scale, Paleontology lesson its a matter of time, From the texas memorial museum, Dawn wagner, The geological time scale, Geological timeline. Remember, the use of time, volume, or mass in your metaphor would be just dandy.
A wide diversity of marine and terrestrial , including plants and animals, can be found locally in the park and some are preserved in university collections. It gives students an opportunity to place various fossils into appropriate periods, observe the change in the complexity of fossils and draw conclusions regarding the change. It is nearly impossible for the human mind to comprehend the amount of time that it has taken for the Earth to develop to its present state, yet we try to imagine each stage of its unfolding and the time that passed during each phase of development. Kate Ruhl, Massachusetts Institute of Technology Landscape evolution provides a convenient framework for understanding geologic time and rates because students can observe how processes like erosion and deposition shape their surroundings. An organization providing resources, professional development, education conferences, and much more! Students will demonstrate that the geologic time scale does not divide the age of Earth into equal parts as our clock or calendar does.
Note: At present, information about individual epochs can be found within their respective periods. Randall Richardson, The University of Arizona After having talked about the geologic time scale, I ask for two volunteers from the class to hold a rope that is 50 feet long. Images, code, and content on this website are property of Geology. Geologic Time Scale Activities Showing top 8 worksheets in the category - Geologic Time Scale Activities. As a reference tool, you can easily note the sequence of the various divisions and the length of each unit of time relative to each other. Animals have changed over time as evidenced by the fossil record.
