The Earth Observatory Glossary defines words from space science, ecology and Earth science. It is part of the NASA Earth Observatory site, which provides new satellite imagery and scientific information about Earth with a focus on climate and environmental change. The new glossary mode allows users to browse the Earth Observatory site with special terms highlighted that, when selected, will take you to the appropriate entry in the glossary.

In this demonstration, evidence of the Earth's rotation is observed. A tripod, swiveling desk chair, fishing line and pendulum bob (e.g., fishing weight or plumb bob) are required for the demonstration. 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.

This magnetism teacher‰Ûªs guide is one of four activity guides‰ÛÓplus a background guide for teachers‰ÛÓthat provide students with the opportunity to build on science concepts related to Earth‰Ûªs magnetism and its changes, as detected by THEMIS magnetometers located in schools across the U.S. The four activity guides have been used in different types of classes, from physical science and physics classes, to geology classes and astronomy classes. The excitement of actually participating in the THEMIS project helps motivate the students to learn challenging physical science concepts.
The background guide for teachers, the THEMIS GEONS Users Guide describes the important role that terrestrial magnetism plays in shaping a number of important Earth systems. It also explains the basic operating principles behind magnetometers‰ÛÓparticularly the system you are now in the process of using to investigate magnetic storms at your school.
Earth‰Ûªs Magnetic Personality is the fourth and final guide, which was developed with the goal that students can work directly with the THEMIS magnetometer data. The guide covers vectors, the x-y-z magnetometer plots, creating a prediction for aurora using the magnetometer data, calculating the total magnetic field strength and observing it over months, and the waves in Earth‰Ûªs magnetic field excited by large magnetic storms.

This lesson will help students understand the cultural nature of scientific research. Students explore famous scientists, their theories, places of origin, and their culture. They document scientific viewpoints of famous scientists throughout history and discuss geographical region, culture, gender, and other factors effecting scientific theories and discoveries. This activity helps students understand the cultural nature of scientific research and how people interpret science in different ways based on their social environments. This activity is one of several in the Swift: Eyes through Time collection available on the Teachers' Domain website.

To gain an understanding of mixtures and the concept of separation of mixtures, students use strong magnets to find the element of iron in iron-fortified breakfast cereal flakes. Through this activity, they see how the iron component of this heterogeneous mixture (cereal) retains its properties and can thus be separated by physical means.

This is a children's science story about gravity (title translated: The World of Copocuqu: Queen Gravity and King Mass). Learners will read about the force of gravity and how it relates to the mass of a body. The story takes place in an asteroid in which all its inhabitants talk in the form of questions or the world of Copoqucu. The story ends with a magic secret (or learning capsule), which reflects in synopsis the science message that the child would take with him or her.

This is an activity about magnetic induction. Learners will induce a flow of electricity in a wire using a moving bar magnet and measure this flow using a galvanometer, or Am meter. Through discussion, this activity can then be related to magnetic fields in nature. This activity requires use of a galvanometer, bar or cow magnet, and wire. This is the fifth lesson in the second session of the Exploring Magnetism teacher guide.

Play hockey with electric charges. Place charges on the ice, then hit start to try to get the puck in the goal. View the electric field. Trace the puck's motion. Make the game harder by placing walls in front of the goal. This is a clone of the popular simulation of the same name marketed by Physics Academic Software and written by Prof. Ruth Chabay of the Dept of Physics at North Carolina State University.

This is an activity about electromagnetism and the Sun. First, learners will do a KWL activity using six vocabulary words. Next, they will build an electromagnet and investigate how it works. Finally, learners will relate the workings of their electromagnet to a Solar Dynamics Observatory magnetogram image of the Sun. Per group of learners, this activity requires materials such as a length of insulated wire, alligator clips, a 2-D-battery holder, two D-batteries, and a nail.

This is a hands-on lab activity about the chemical composition and conductivity of water. Working in groups, learners will: conduct an experiment involving the process of electrolysis, prepare an experiment to better understand the process of ion exchange, discuss and research the "softness" and "hardness" of water, and use the periodic table to identify elements and learn their characteristics. Background information, a glossary and more is included. Materials needed for each student group include a 9-volt battery, two electrodes (e.g. copper strips, or two #2 pencils sharpened at both ends), electrical wire and glass beakers or ceramic saucers. This activity is part of the Aquarius Hands-on Laboratory Activities.
