Introductory spreadsheeting, graphical display, and modeling through simulation of scarp evolution
In this spreadsheet modeling exercise, students use a simple arithmetic model to simulate the evolution of an escarpment across time. Although the output closely resembles an evolving scarp, no real variables are included in the model. Students will develop basic spreadsheet and graphical display skills. Learning goals, context for use, teaching tips, materials, assessment tips and related resources are provided.
How mentors can serve as role models, helpers, and colleagues.
The Hindu epic The Ramayana is retold through the mural, painting, and dance of Southeast Asia.
This activity leads students through derivations of the equations associated with radiometric dating: the radioactive decay equation, the half-life equation and the age equation. After the equations have been derived, students are asked to apply them to geologic applications. This activity is appropriate for lower division undergraduates. Learning goals, context for use, teaching tips, materials, assessment tips and related resources are provided.
GEOLogic: Museums and their Dinosaur Displays
GEOLogic questions are puzzles that were developed to support students understanding of geoscience concepts while challenging them to develop better logic and problem solving skills. In this exercise, students are asked to match five top museums with two fossils that they have on display based on clues presented from various points of view. This activity is appropriate for a high school science class or an introductory level undergraduate geoscience course, and can be given as an in-class assign
GEOLogic: How Much of the State is Wet
GEOLogic questions are puzzles that were developed to support students understanding of geoscience concepts while challenging them to develop better logic and problem solving skills. In this exercise, students are asked to match up students with their home state, and their states with the area and percentage of area of surface water that they contain, as well as where each of the states rank nationally in terms of water area. Students are given clues from various perspectives to help them deduce
GEOLogic: Continental Drift and Plate Tectonics
GEOLogic questions are puzzles that were developed to support students understanding of geoscience concepts while challenging them to develop better logic and problem solving skills. In this exercise, students are asked to match up lecturers with what day and time they teach, and how many students they have in each class based on clues given from several different perspectives. In the second part of the activity, students are asked to learn more about the historic figures mentioned by doing read
Earth's history in 4.56 meters: constructing a timeline with calculator tape
In this short activity, students make a timeline of Earth's history using calculator tape. The tape is 4.56 meters long, so that one billion years is equal to one meter.
