Ground Penetrating Radar (GPR):
Seeing Below the Surface While Keeping Scientists Safe
Overview
Ground Penetrating Radar (GPR) is a valuable technology that utilizes waves of low frequency electromagnetic radiation to help polar scientists understand what is beneath their feet! Using real field data from the Icelandic glacier Múlajökull, along with a small selection of short videos and web-based resources
In this activity students learn about varves, annual sediment layers found in lakes. Students will analyze authentic varve data from New England in order to correlate data from three different geographic locations .
Objective
Students will analyze authentic varve sediment data and create a graph of varve thickness. Students will use their results to make inferences about
This lesson allows students to use online mapping tools to investigate global snow cover changes. Students develop a problem statement about global snow cover and then use mapping tools to investigate their problem or question.
Objective
Students will become familiar with the data and tools used to analyze snow cover changes in order to answer questions pertaining
This activity is designed to take place near or at the end of a unit on the ocean floor. Students should be familiar with the physical features of the ocean floor including the continental shelf, abyssal plain, seamounts and guyots, seafloor ridges and trenches, and submarine canyons. The students should have also previously learned about sonar methods for mapping the
In this lesson, students learn about what archaeologists do and then practice implementing these skills with "real artifacts".
Objective
Students will:
* be able to define an artifact and an archaeologist.
* use evidence to support their decisions about the origin and use of an unknown item.
The study of rock and sediment layers, or stratigraphy, can be used to introduce students to the fundamental principles of geology and to lead into the idea of geologic time. In this lesson, students are introduced to Nicolas Steno's 3 major laws of stratigraphy: the law of original horizontality, the law of superposition and the law of lateral
