This is the homepage of the National Oceanic and Atmospheric Administration/Pacific Marine environmental Laboratory (NOAA/PMEL) North Pole web cams. The web cams operate during the Summer warmth and daylight (April - October) and are redeployed each Spring. The images from the cameras track the North Pole snow cover, weather conditions and the status of PMEL's North Pole instrumentation, which includes ... Full description.

This interactive timeline provides information on every mission that has gone to the moon, including both manned and unmanned missions originating from different countries. The student can move a pointer to any relevant date or mission name and receive statistical information about each flight as well as a complete description of methods and accomplishments.

In this lesson students investigate bathymetric mapping of deep-sea habitats to see how deep-sea areas of the northwestern Hawaiian Islands can be mapped to facilitate their exploration with a manned submersible. Students will create a two-dimensional topographic map from bathymetric survey data, a three-dimensional model of landforms from a two-dimensional topographic map, and will interpret two- ...

In this video lecture, Helen Sharman, the first British astronaut, gives an account of her personal experiences on the space station Mir. Using models and film to illustrate key scientific concepts, she discusses the way the Third Law of Newton and convection apply to rockets, space flight, weightlessness and survival. Sharman explains how breathing, eating, using the toilet, and recycling were accomplished ... Full description.

This downloadable educator's guide provides lessons about space suitable for younger students which are designed to stimulate an active curiousity about the Sun-Earth connection. The thirteen lessons are divided into three groups. The first group of lessons illustrates how scientists work with technology to gather data and extend their senses. The second group helps to explain how scientists investigate ... Full description.

In this activity, students will learn how a satellite communicates information to the earth. They will discover that satellites use a transmitter and reciever system to send information and that the information must be transmitted correctly, recieved, and understood for effective communication. They should also understand that satellites transmit information as a stream of numbers, and gain experience ... Full description.

In this activity students investigate the role of the Radio Plasma Imager (RPI) on the Image for Magnetopause-to-Auroral Global Exploration (IMAGE) satellite. They will discover that the RPI is capable of remotely sensing and determining the density, distance, and velocity of electrically charged clouds. The activity explores how radar works and how the data is collected and organized to form images. ... Full description.

In this activity, students work in groups to research Galileo Galilei, Johannes Kepler, Hans Lippershey, or James Metius, scientists who all made advances related to the telescope. Each group will share results by making a presentation to the class. Then the class will decide who, if anyone, they think should be given credit for inventing the telescope, and why. They will then summarize their findings ... Full description.

In this activity students use simple materials to make model sailboats which must stay upright and sail straight in a testing tank. The activity introduces the terms sail, stability, leeway, resistance, floating, displacement, propulsion, steering, and keel. Sailboat hulls are designed to pursue a straight-ahead course with as little disturbance of the water as possible. At the same time the boat ... Full description.

In this activity, the process of finding the epicenter of an earthquake with a travel time graph is simulated. During the course of this activity students will model how earthquake waves travel through the Earth at different speeds, construct and utilize a graph to characterize the relationship between distance and time of travel of seismic waves (a travel time-curve), and use the constructed time-travel ...
