This monument, established in December 1907, was among the first sites protected under the Antiquities Act of 1906.
The aim of this lesson is to enable students to be aware of how to manage their approach to studying to reduce stress. It is the fifth lesson in the study skills series and is intended to support adult learners who are embarking on a course of study and need to acquire skills which will help them to be successful. The lessons are designed as a package with key skills reinforced in each subsequent lesson so that a study culture is developed over time. They can be delivered sequentially or used in

Then they learn about the magnetic Earth and the use of compasses and angles. Students also learn about the difference between relative and absolute locations. Throughout this activity, students practice using a variety of math skills.
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.
