APL-UW staff volunteer their time and expertise to provide learning opportunities to students and educators from across the Pacific Northwest. Summaries of presentations offered by APL-UW scientists are listed here.
Contact Bob Odom or Ellen Lettvin, Assistant Directors for Education Programs, if you wish to schedule a visit to the Lab or request a scientist to come to you and your students.
| Oceanography: From Sea Life to Global Climate |
An APL-UW oceanographer provides a tour of a small-scale physical oceanography laboratory and a presentation of interesting physical oceanography problems—how they relate to marine life, coastal life, and climate. The presentation includes a slide show of recent field work in oceans around the world.
This presentation is appropriate for students grades 9–12 and can accomodate one classroom (about 25) students.
| Mechanisms of Space Flight |
Description: slide presentations with interactive, Q&A session
An APL-UW engineer gives the presentation at the Laboratory or in a classroom setting to students grades 9–12.
| Mathematics of Image Processing |
Description: slide presentations with interactive, Q&A session
An APL-UW engineer gives the presentation at the Laboratory or in a classroom setting to students grades 9–12.
| Underwater Vehicle Flight |
Description: slide presentations with interactive, Q&A session
An APL-UW engineer gives the presentation at the Laboratory or in a classroom setting to students grades 9–12.
| Technologies Used to Observe the Ocean |
Members of the Laboratory Integrated Observational Platforms Group give hands-on demonstrations of underwater gliders and towed instruments. They explain how they are used to investigate questions of arctic science, biological and physical interactions in the ocean, and mesoscale ocean processes.
The demonstration can be geared to any age group.
Dr. Williams and three graduate students present one lecture per week on environmental acoustics, oceanography, and engineering at APL-UW. The class will give high school physics students an opportunity to interact with college graduate students and to see how physics are applied to real-world problems.
See http://sorfed.apl.washington.edu/class/
The classes will be taught May 22, 2007 – June 9, 2007 (one class period each week for three weeks), and is appropriate for high school junior and senior physics students

| Water, Ice, and the Arctic |
Discuss the ocean, salt, and the Arctic. Pictures of polar bears and other arctic animals shown. Some arctic research equipment and required clothing are shown and tried on. Partially frozen paper cups illustrate how water turns into ice. Experiment: a small toy fish is dropped into one cup per student; salty ice cubes are made overnight. The next day they can be left out to melt, and the toy fish recovered. The salty water can be left to evaporate for several days and salt crystals at the bottom of the cups can be drawn.
The presentation is geared for pre-school–kindergarten age children.
Discuss the Arctic and how it differs from the Antarctic. Discuss properties of sea ice. Microscopic photos illustrate the brine channels that run through sea ice and support some life forms. Liquid nitrogen is used to freeze items such as flowers and water balloons, some of which contain salty water. Food coloring is used to show that the salty ice has brine channels, freshwater ice does not.
The presentation is geared for students grades 1–8.
| Ocean Salinity: From the Arctic to Your Tongue |
Why is the ocean salty? Global hydrologic cycle and the global salt cycle are discussed. The Arctic Ocean is quite fresh; why? Salinity affects ocean currents in the Arctic much more than in other places on the globe for interesting reasons. Salinity Taste Test: each student tastes three tiny samples of water with different salinities, and tries to place them in order. The tongue is a very sensitive salinometer. A CTD instrument, which measures salinity in the ocean electronically, is shown.
The presentation is appropriate for students grades 5–12.
| Climate Change and the Arctic |
PowerPoint lecture with Salinity Taste Test if there is time. Discussed are the Arctic, the greenhouse effect, and global warming. The Arctic is particularly sensitive to global warming. Study global average temperature histories from the past 150 years, 2000 years, 200,000 years, and 600,000,000 years, and the projected changes over the next 100 year, i.e., the "hockey stick" plot. Discuss sea level rise. Photos of field work in the Arctic are presented.
The presentation is geared for students grades 9–college.
