This activity is designed to be used as a jigsaw. Although each component could be individually used as desired. The activity is meant to be conducted in a three-phase approach.

Phase 1 involves small groups of "experts" focusing on one of our narrow topics related to ocean acidification. Students work together, using the Internet as necessary, to complete a short 10-15 minute activity while the instructor roams the room to clarify issues that arise.

Phase 2 involves small groups made up of one "expert" from each of the expert groups. This interdisciplinary group will work through a short 10-15 minute activity that encompasses the knowledge from each of the "experts" while the instructor roams the room to clarify issues that arise.

Phase 3 involves the entire class as a whole and to discuss and reflect upon the findings from each interdisciplinary group. The instructor leads this discussion.

This is a short NASA video on the water cycle. The video shows the importance of the water cycle to nearly every natural process on Earth and illustrates how tightly coupled the water cycle is to climate.

This demonstration shows that an increase in temperature will speed up the water cycle. One outcome will be an increase in rainfall. A second outcome will be the increase in total evaporation of water and subsequent drought. Materials required include two aquariums, plastic wrap, 2 clamp lamps with 60 watt light bulbs, pebbles and rocks, modeling clay, blue food coloring, and water. Student worksheets, background information for teachers, and a scoring rubric are included. This is Activity 2 in Too Many Blankets, a module in the lesson series, Potential Consequences of Climate Variability and Change.

Where the tropical ocean meets the sea, a peculiar kind of plant thrives in shallow, salty water. These mangrove plants are incredibly important for shoreline protection and baby fish habitats. In this video, Jonathan investigates life in mangroves by visiting both Caribbean and Pacific mangroves. Please see the accompanying study guide for educational objectives and discussion points.

Using a computer interactive tool, students investigate the changes in coastline that would result from a change in sea level, and suggest what factors could cause a rise in sea level. The activity asks students to reflect on outcomes of their investigations completed during the Ice Ages and Night Life activities, all of which are part of Space Update, a collection of resources and activities provided to teach about Earth and space. Summary background information, data and images supporting the activity are available on the Earth Update data site. To complete the activity, students will need to access the Space Update multimedia collection, which is available for download and purchase for use in the classroom.

This six-day unit provides an in-depth look at the dynamic forces at work on the sea floor. Throughout the unit, students collect their findings in a portfolio. The comprehensive curriculum materials include teacher tools such as individually downloadable readings and detailed daily breakdowns of tasks, a hands-on experiment, three activities about how scientists find deep sea vents and two activities about the thriving ecosystems found in deep sea vents.

SYNOPSIS: In this lesson, students explore different methods of desalination.

SCIENTIST NOTES: This lesson teaches students about potable water scarcity and then explores desalination as a possible solution in water-stressed areas. Desalination technologies are introduced, and energy and environmental costs of desalination are discussed. A video resource explores a novel desalination technology, the Solar Dome, being built in Saudi Arabia. Students are tasked with designing and building their own solar still, and opportunity is given for design optimization. This lesson is recommended for teaching.

POSITIVES:
-This lesson can be multidisciplinary and can be completed in engineering, computer science, digital art, English or science classes.
-Students and teachers are given voice and multiple areas of choice in this lesson.
-Students become agents of change in their own communities, identifying problems and solutions.
-Students and teachers can make this conceptual, practical, or hands-on.
-This lesson can be spread out over several days and be considered a mini-unit.

ADDITIONAL PREREQUISITES:
-Students should be familiar with the basics of climate change.
-Students should be familiar with the basic scientific concepts of osmosis.
-Students should be familiar with basic engineering concepts like scaling and design.

DIFFERENTIATION:
-Students can work independently or in a group with adjusted requirements.
-Teachers can use subject and grade level vocabulary already being worked on or learned in class. Teachers can add vocabulary words in the glossary slide of the Teacher Slideshow.
-To further develop practical science or engineering skills, students can work together to create and implement a workable desalination solution at the school, home, or community level. Students can lead a workshop for family, an environmental club, or the community.
-Some students may wish to communicate their advocacy via social media. Make sure to follow all school rules and monitor students’ progress if you allow this in the classroom.

The Great Pacific Garbage Patch (GPGP) is an intriguing and publicized environmental problem. This swirling soup of trash up to 10 meters deep and just below the water surface is composed mainly of non-degradable plastics. These plastic materials trap aquatic life and poison them by physical blockage or as carriers of toxic pollutants. The problem relates to materials science and the advent of plastics in modern life, an example of the unintended consequences of technology. Through exploring this complex issue, students gain insight into aspects of chemistry, oceanography, fluids, environmental science, life science and even international policy. As part of the GIS unit, the topic is a source of content for students to create interesting maps communicating something that they will likely begin to care about as they learn more.

In this activity, students will use hot and cold water to see how fluids at different temperatures move around in convection currents.

This is a hands-on lab activity about the chemical composition and conductivity of water. Working in groups, learners will: conduct an experiment involving the process of electrolysis, prepare an experiment to better understand the process of ion exchange, discuss and research the "softness" and "hardness" of water, and use the periodic table to identify elements and learn their characteristics. Background information, a glossary and more is included. Materials needed for each student group include a 9-volt battery, two electrodes (e.g. copper strips, or two #2 pencils sharpened at both ends), electrical wire and glass beakers or ceramic saucers. This activity is part of the Aquarius Hands-on Laboratory Activities.

In this activity, students learn about ocean currents and the difference between salt and fresh water. They use colored ice cubes to see how cold and warm water mix and how this mixing causes currents. Also, students learn how surface currents occur due to wind streams. Lastly, they learn how fresh water floats on top of salt water, the difference between water in the ocean and fresh water throughout the planet, and how engineers are involved in the design of ocean water systems for human use.

Do shark feeding frenzies really exist? Will sharks turn into a bunch of cannibals if they start competing for food? In this video, Jonathan wants to find out, and travels to Micronesia for an experiment. You won‰ŰŞt believe the fantastic result! Please see the accompanying study guide for educational objectives and discussion points.

This lesson examines the effects of surface energy transfer and storage on ocean temperatures. Included are activities that introduce the use of scientific models. Students then use an energy flow computer model to track energy changes by manipulating four variables: solar energy, heat transfer, water transparency, and seasons of the year. Note that this is lesson four of five on the Ocean Motion website. Each lesson investigates ocean surface circulation using satellite and model data and can be done independently. See Related URL's for links to the Ocean Motion Website that provide science background information, data resources, teacher material, student guides and a lesson matrix.

In this activity, students are presented with a satellite image of ocean temperature, and examine the map to determine whether ocean temperature is influenced by latitude. Students graph each temperature value as a function of latitude and write a linear equation that best fits the points on their graph. A student worksheet is provided. Summary background information, data and images supporting the activity are available on the Earth Update data site. To complete the activity, students will need to access the Space Update multimedia collection, which is available for download and purchase for use in the classroom.

In this exercise students work with light, temperature, and phytoplankton biomass proxy (chlorophyll a concentration) data to;
