Subject: Mathematics,Science Title: Do You Hear What I Hear?
Add Bookmark
Description: In this lesson, from Illuminations, students explore the dynamics of a sound wave. Students use an interactive Java applet to view the effects of changing the initial string displacement and the initial tension. Thinkfinity Partner: Illuminations Grade Span: 9,10,11,12
Subject: Mathematics,Science Title: Shedding the Light
Add Bookmark
Description: In this fourlesson 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.

Subject: Mathematics,Science Title: Make a Conjecture
Add Bookmark
Description: In this lesson, one of a multipart 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. Thinkfinity Partner: Illuminations Grade Span: 9,10,11,12
Subject: Mathematics,Science Title: Gather Data
Add Bookmark
Description: In this lesson, one of a multipart 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. They conduct three experiments including a simulated ocean dive, using tinted Plexiglas to simulate water depth, and measuring light intensity within a column of water.

Subject: Mathematics,Science Title: Reflect on Your Work
Add Bookmark
Description: In this lesson, one of a multipart 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.

Subject: Science  Ecology  Social Studies  Geography  Social Studies  World History 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 buildup. They look at incidents involving submarines both during and after the Cold War, including the K19 disaster. Finally, students assemble their findings into a classroom presentation.

Subject: Science  Earth science  Science  Oceanography  Social Studies  Geography Title: Wave Properties
Add Bookmark
Description: In this lesson, from Xpeditions, students learn the components of a wave then discuss the effects of wave height, wavelength, and wave period in determining the overall size of a wave. They use the National Geographic Wave Simulator to experiment with creating different kinds of waves. Discussion then focuses on the effects of geography on wave size as well as additional forces on boats trying to navigate waves.
