This activity is about underwater mapping and its importance in deep-water exploration. Working in groups, learners will use bathymetric survey data to create a two-dimensional topographic map. They will use that map to create a three-dimensional... (View More) cardboard model of landforms, such as an underwater volcano. The students will be able to interpret two- and three-dimensional topographic data and consider how they might plan for future diving missions based on the analysis of this data. Extensions to this activity are available. This is the first of three activities in the "Impact of Climate Change on Hawaiian Monk Seals" section of Climate Change, Wildlife and Wildlands: A Toolkit for Formal and Informal Educators.

Students in grades 7-10 analyze land cover change in order to help them grasp the extent, significance, and consequences of land cover change; and to introduce them to the perspective of space-based observations.
This is an activity about measuring angular size and understanding the solar and lunar proportions that result in solar eclipses. Learners will use triangles and proportions to create a shoebox eclipse simulator. They will then apply what they learn... (View More) about angular size to predict the diameter and distance of one object that can be eclipsed by another. They will also complete three journal assignments to record observations and conceptual understanding. This activity derives from those demonstrated in the NASA CONNECT television series episode, titled Path of Totality. (View Less)
In this activity, learners will analyze a satellite image of the Missouri River to find evidence that a river channel has changed position over time. They will then build a display, such as a poster or model, that identifies and describes the... (View More) features that demonstrate channel movement. A link to the satellite image is provided. This activity is part of the Event-Based Science (EBS): Remote Sensing Activities. (View Less)
