Subject: Science
Description: In this Science Update, from Science NetLinks, you'll hear about a device for measuring light that can withstand the intensity of the Sun's rays. Science Updates are audio interviews with scientists and are accompanied by a set of questions as well as links to related Science NetLinks lessons and other related resources.

Subject: Health, Science
Description: In this Science Update, from Science NetLinks, you'll hear why bright nighttime lights could be bad for women's health. Science Updates are audio interviews with scientists and are accompanied by a set of questions as well as links to related Science NetLinks lessons and other related resources.

Title: Shedding the Light      Add Bookmark
Description: In this four-lesson unit, from Illuminations, students investigate a mathematical model for the decay of light passing through water. The goal of this investigation is a rich exploration of exponential models in context. Students examine the way light changes as water depth increases, conduct experiments, explore related algebraic functions using an interactive Java applet and analyze the data collected.

Title: Make a Conjecture      Add Bookmark
Description: In this lesson, one of a multi-part unit from Illuminations, students explore the development of a mathematical model for the decay of light passing through water, in a rich exploration of exponential models in context. Students view a picture and QuickTime video clip and then make conjectures about the relationship between light intensity and water depth.

Subject: Mathematics,Science
Description: In this lesson, one of a multi-part unit from Illuminations, students examine, reexamine, and compare the results obtained in previous lessons to enrich their mathematical understanding. Possibilities for students include examining the method of data analysis, asking What if questions, connecting the situation with other contexts, and further exploring the method of linearizing data.

Title: Submarines: Underway on Nuclear Power      Add Bookmark
Description: In this lesson, from Xpeditions, students consider the role of nuclear submarines during the Cold War. They explore the uses of nuclear submarines, the dangers faced by their crews, and the effect of the Cold War build-up. They look at incidents involving submarines both during and after the Cold War, including the K-19 disaster. Finally, students assemble their findings into a classroom presentation.
