During the Covid lockdown, the society has been presenting virtual excursions to Scottish geological localities. These presentations have been recorded and are available to view on YouTube. The following presentations are currently available. The stromatolites of the Bonahaven Dolomite Formation exposed on the north coast of Islay are some of the best examples of these ancient relics of Precambrian life in the world. This virtual field trip allows you to see them and other fantastic geology in this remote and hard-to-get-to location. In addition, there are some old lead mines dating back to the 14th century and evidence of possibly the earliest human habitation in Scotland some 11, years ago. Webster, R. Skelton Ringwood Publishing, David Webster has also presented virtual excursions to Jura and Colonsay as part of the Geowalks Lockdown Lectures series, and a virtual excursion to Islay to the Royal Philosophical Society of Glasgow. He has also presented a more technical excursion to the southern Rhinns of islay to the Open University Geological Society.
Radioactive Dating Game
This activity consists of 2 parts created by different entities. The simulation has instructions on the left side of the screen with a bar that can be scrolled forward as you proceed. The icons are interactive at the bottom of the page: a nail with a tag and a magnifying glass, the computer, a chisel and a specimen collection box.
The dig site number is displayed at the top so students can keep track of which site they are using. The worksheet provides the background, procedure and data tables from each dig site organized in a way that the data can be easily transferred and analyzed.
A series of interactive modules that explore the history of life on Earth, while focusing on the processes of science. Target Grade Levels. Getting Into the Fossil Record helps students gain a basic understanding of what a fossil is and how a fossil forms. Stories From the Fossil Record provides students with a basic understanding of how fossils can be used to interpret the past. There are four different pathways to explore: biodiversity, geologic time, paleoecology and past lives.
What Did T. Adventures at Dry Creek virtually engages students in scientific research. The Evolution of Flight examines evidence from the fossil record, behavior, biomechanics and cladistic analysis to interpret the sequence of events that led to flight in the dinosaur lineage. Students gather, organize and analyze data and then propose hypotheses about the evolution of flight in birds.

World map showing cratons. Source: American Museum of Natural History. Let’s get back to Africa! Where has Africa been for the past 4. It hasn’t looked the same as it does today; because of plate tectonics, it has moved around the globe and changed in size and shape. These maps are our best reconstructions of where the continental masses were located at various times in Earth’s past.

Geological time scale — 4. Geological maps. Absolute age dating deals with assigning actual dates in years before the present to geological events. Contrast this with relative age dating, which instead is concerned with determining the orders of events in Earth’s past. Scholars and naturalists, understandably, have long been interested in knowing the absolute age of the Earth, as well as other important geological events.
In the ‘s, practitioners of the young science of geology applied the uniformitarian views of Hutton and Lyell see the introduction to this chapter to try to determine the age of the Earth. For example, some geologists observed how long it took for a given amount of sediment say, a centimeter of sand to accumulate in a modern habitat, then applied this rate to the total known thickness of sedimentary rocks. When they did this, they estimated that the Earth is many millions of years old.
Geologists were beginning to accept the views of Hutton that the Earth is unimaginably ancient. The answer is radioactivity. Hypotheses of absolute ages of rocks as well as the events that they represent are determined from rates of radioactive decay of some isotopes of elements that occur naturally in rocks.
Virtual Dating Geology Lab – Finding Lab Activities Online
As many us work on developing online courses we have to ask ourselves how to implement lab activities. Listed below are some example lab activities that you might find useful as examples of others have used or even as lab activities to have your students do. Please make sure when using these activities to acknowledge the authors of the page. If you know of other sources of activities that you find useful for online courses, we encourage you to fill out an activity submission form or share them with the community.
There is also a growing collection of online lab activities identified within the Teach the Earth collections. Your Account.
What key discovery, then, allowed geologists to begin assigning absolute age dates to rocks and ultimately discover the age of the Earth? The answer is.
Relative dating is used to arrange geological events, and the rocks they leave behind, in a sequence. The method of reading the order is called stratigraphy layers of rock are called strata. Relative dating does not provide actual numerical dates for the rocks. Next time you find a cliff or road cutting with lots of rock strata, try working out the age order using some simple principles:. Fossils are important for working out the relative ages of sedimentary rocks.
Throughout the history of life, different organisms have appeared, flourished and become extinct. Many of these organisms have left their remains as fossils in sedimentary rocks. Geologists have studied the order in which fossils appeared and disappeared through time and rocks. This study is called biostratigraphy.
