Sounds of the Sun
The sounds of the sun are the focus of this two-minute episode of the radio program Pulse of the Planet. The episode is available here in text and audio formats, the latter of which features time-compressed sun sounds. The episode's host and his guest, a solar physicist, explain the dynamics that cause our sun to oscillate and produce sound waves. The sound data was collected by the space-based Solar and Heliospheric Observatory (SOHO). In analyzing the sun's sounds, scientists detected jet stre

The baby's brain : infant vision
In this feature, the user explorers how a baby's sense of sight develops. By dragging a slider bar to each of six different age markers, the user can see how the same image looks for babies as they get older. There is also a paragraph-long explanation of vision at each of the six ages shown: newborn, 1 month, 2 months, 3 months, 6 months, and adult. These explanations reveal what a baby can and cannot see at each age. They also discuss how a baby's brain and eyes mature, providing improved focus

Examine global surface currents
This Earth science animation is designed to help high school students visualize the causal relationship between global winds and the temperature and direction of ocean surface currents. The animation presents a world map that shows the direction of surface currents, which are color-coded to indicate warm and cool temperatures. Moving the cursor over the map superimposes gold arrows that indicate wind direction. The introduction summarizes the relationship and calls students attention to the temp

Water reclamation plant
In this video clip, students see how wastewater is treated at a water reclamation plant. One of the plant's operators gives Bob the Vid Tec (a children's programming host) a tour of the plant, describing along the way what happens at each step in the water treatment process. For example, the operator explains that microorganisms are used to consume human waste in the biological nutrient removal step. Bob also talks with another plant operator about why kids should learn about wastewater treatmen

English Language Learners in the Science Classroom
What can we as teachers do to help English Language Learners (ELLs) learn science when we do not speak their languages or know their cultures? Both pre- and in-service teachers have successfully used the following strategies in teaching in teaching language and cultural minorities. These strategies can be, and often are, used by ESL (English as a Second Language) teachers in pull-out programs.

Tessellate!
This Java applet enables students to create tessellations, which are patterns on a plane that do not overlap. The student selects a hexagon, rectangle, or triangle to distort by dragging edges and the newly formed corners. Users can select colors for the pattern, and a button displays information in a second window. The window lists the coordinates of the vertices, angle measures, side lengths, area, and perimeter for the shape. From the applet page, What, How, and Why buttons open pages that ex

Observe the retreat of ice sheets from North America
In this Earth science animation, middle and high school students observe the retreat of ice sheets in North America for the past 18,000 years. Students are instructed to observe the animation carefully to see how the sea level changes as the ice sheets retreat. The animation presents images in 1,000-year increments from 18,000 years ago to the present. Movie controls allow students to repeat, pause, or step through the animation, which can give students more time to analyze how the shape of the

Scope on Safety : Waste not, want not
Planning chemical use and disposal is critical to a safe laboratory environment. It is irresponsible to simply go out and purchase laboratory chemicals without considering why they are needed and how they will be disposed of when they are no longer needed. An OSHA-based Chemical Hygiene Plan (CHP) should be adopted by the science department as the first step in this vital process. The procedures and operations for the purchase, use, storage, and recycling of hazardous chemicals are addressed in
