In this activity guide, students use various mathematical skills in the context of examining an ISS EarthKAM image (ISS 004.ESC1.03221557) of farmland in Texas and New Mexico. They randomly select a sample region of the image, count the number of fields in that region, and estimate how many fields are in the entire image. They check how reasonable their estimate is, compare estimates, discuss differences ... Full description.

This book of 19 essays, written by Earth scientists, provides insight into the dynamic processes that shape the Earth. The essays are supported by case studies describing a range of research projects (including Looking for Life in Antarctica-and Mars, Mapping Mt. Rainer, and Mapping Hot Springs on the Deep Ocean Floor) and profiles of historically significant Earth scientists (Including Inge Lehmann, ... Full description.

This collection of images shows geologic features in many of the country's national parks. The collection is searchable by park name, state, year, or by the name of the photograph. Each photo is accompanied by a brief caption that provides the photographer's name, the date, and a description of the photo. Full description.

In this lesson, students will understand that local rocks are different and are used in various ways. Following a directed reading and discussion, the students engage in an activity in which they 'dig up' rocks from a sand-filled bucket and state what type of rock they think it is and why. Full description.

In this lesson, students will learn that continental plates drift and this affects the layers of the earth. Following a directed reading and discussion, they will perform an experiment in which they use chocolate frosting and graham crackers to simulate tectonic plates sliding about on the mantle.

In this activity, students will learn to identify the distinguishing characteristics of a stone wall. They will first draw a picture of a stone wall from memory, then go outside to view and sketch a real wall. Following the field activity, they will construct models of walls using modeling clay. A recipe for the clay ('model magic') is provided. Full description.

In this two-day lesson, students will discuss the formation of rocks in earth history, hear about earth history, discuss the importance of respect and stewardship of past and present, and consider height, width, texture and shape when making rock representations. Following a review of previous explorations of stone walls, they will read and discuss geological concepts, particularly what a rock looks ... Full description.

This demonstration will help students identify and describe the process of erosion and transfer this knowledge from class exercises to real world examples. The teacher will explain the demonstration and how it depicts the process of erosion; students will make predictions about what will happen when hot chocolate is poured over ice cream, and record their predictions as well as their observations ... Full description.

In this lesson, students will learn to identify and describe the Earth process of erosion, transfer their knowledge from class exercises to real world examples, and analyze the process to better understand the way in which the land is shaped by earth processes. They will locate some prominent caves in a world atlas, construct their own map showing the locations, and construct a model that simulates ... Full description.

This document describes two teacher's kits that were developed to facilitate hands-on experiences and outdoor instruction and broaden the experience of using 'Stone Wall Secrets' in the classroom. Each one contains rock samples similar to those encountered by the protagonist in the book, as well as equipment (magnifying glass, compass, etc.) that will aid students in their outdoor investigations of ...
