Learners will use trays of sand and cups of water to recreate surface features seen in images of Mars. This is activity 5 of 9 in Mars and Earth: Science Learning Activities for After School.

This ChemMatters article provides a brief background on smog, then examines the causes of it, efforts to reduce it, and methods used to measure it. ChemMatters is an educational magazine for high school students.

This article describes key aspects of the nature of science by comparing the reactions to a sensational story between scientists and non-scientists. This resource is from PUMAS - Practical Uses of Math and Science - a collection of brief examples created by scientists and engineers showing how math and science topics taught in K-12 classes have real world applications.

How big and how old is the universe? This culminating telescope investigation for high school students has them first taking images of galaxies near and far; then measuring and calculating their distances; then predicting how they might expect galaxies to be moving based on various models of gravity; and then comparing their results with the galaxy velocity measurements in a NASA database. From this data, students explore the concept of an expanding universe and can actually determine an estimate for the age of our universe. This activity is part of a DVD that is a professional development resource for educators. Many new astronomy learners, students and adults alike, are unfamiliar with the universe beyond the solar system. Instructions for obtaining the DVD and registering for the professional development workshop are contained on the website.

Dieter Hartmann, a high-energy physicist, presents a story-based lesson on the science of Gamma-Ray astronomy. The lesson focuses on gamma-ray bursts; examining their sources, types, and links to the origin and evolution of the Universe. The story-based format of the lesson also provides insights into the nature of science. Students answer questions based on the reading guide. A list of supplemental websites is also included.

This poster highlights a variety of Earth science careers, featuring short biographies from 13 NASA Earth explorers, including scientists, engineers, educators and more. The poster also includes information about NASA's unique perspective on the Earth, one educator's story about how he uses NASA Earth science data and materials in his middle school classroom, and a collection of classroom activity suggestions.

This site provides fun activities for children to do and make, while they learn about space and Earth science, and the technology that enables science. The Teachers Corner on the WWW site contains curriculum supplements originally published in the ITEA (International Technology Education Association) Technology Transfer Teacher magazine.

This activity is about the use of remote sensing in planetary exploration. Learners will find out how human curiosity in planetary exploration results in science questions, engineering solutions, and teamwork. This activity demonstrates how planetary features are discovered by the use of remote-sensing techniques. Students will experience the different phases in planetary exploration, including telescope observations, fly by missions, orbiters, landers, rovers, and their own ideas about human exploration. The lesson models scientific inquiry using the 5E instructional model and includes teacher notes, prerequisite concepts and vocabulary.

NASA scientist, Neil Gehrels, serves as your guide to this online lesson on gamma ray tools, which focuses on advances in detector technologies since the 1980s that have enabled us to capture and image high-energy phenomena. Dr. Gehrels explains different methods for detecting and imaging high-energy particles, how they work, and the advantages and disadvantages of each, using examples and imagery from NASA missions.

This is an activity about image analysis. Learners will create a map of the room and discuss the perspectives shown in their drawings and how this relates to satelite images. Participants brainstorm a list of features that might be recognizable in satellite photos, search the Earth Images for these features, and place the images in categories depicting these features. This is activity 2 of 9 in Mars and Earth: Science Learning Activities for After School.
