How Does Remote Sensing Help Us to Observe Human Activities on Earth?

The human activity featured in this investigation is the choice of settlement sites. Beginning with an analysis of the location of their own town, students consider the negative and positive aspects of both natural and human made features.

Technology Teacher: Singin' the Black and Blues

Learners will read about and discuss the colors of the day- and night-time skies. They may sing the Top-down Black and Blues, a song about the sky; or they may write a poem, essay, or song about the bluest sky or blackest night they have ever experienced.

Landcover Mapping

Students will use remotely sensed images and topographic maps to classify land cover types in their watershed. A field trip to specific sites will allow the students to ground truth cover types found on the remotely sensed images and extrapolate that information to other sites not visited.

A Sense of Balance: Activity 2

In this activity, students create a reservoir model using hoses, a bucket, a flat pan, and water, to understand the inputs and outputs of a local watershed or reservoir. The resource is supported by teacher background information, assessment suggestions, and a scoring rubric.

Motion of the Sun and Earth: Using a Classroom Model to Explore Rotation and Revolution

This is an activity about the motion of the Sun and the Earth, specifically rotation and revolution. After identifying what they already know about the Sun, learners will observe and manipulate a styrofoam ball model of the Sun and Earth.

Traditions of the Sun: The Sun-Earth Connection at Chaco Culture National Historic Park

This is a companion book to the Traditions of the Sun web site. Learners can use the book to learn about the Sun's dynamic nature, explore images from NASA's cutting-edge solar missions and understand more fully the human connection we all have to our Sun.


In this data analysis activity, students connect the idea of the tilt and orbit of the earth (changing of seasons) with monthly snow/ice data.

Graphing Temperature Data

In this activity, learners will use Excel to graph temperature data sets and learn to derive observations on possible climate change consequences in a given region.

Soil Characterization: Lab Measurements (38:10 min)

This video provides step-by-step instructions for collecting soil samples in the field, and for analyzing and storing soil samples in the lab. Procedures for determining the bulk density, particle density, particle size distribution, fertility, and pH of a soil are demonstrated.

Dark Matter NASA Conference

Students explore the evidence for dark matter using the measurements made by the ROSAT X-ray satellite for a small group of galaxies.
