This is a comprehensive lesson plan on page 85 for a group cleanup trip to a local beach, lake or stream. Learners keep track of the types and amounts of trash picked up and analyze this information.

In this activity on page 24, learners perform experiments to examine whether or not trash can float, blow around, or wash away.

In this activity on page 27, learners perform an experiment to learn about how different types of marine debris degrade and how weather and sunlight affect the rate of degradation.

This activity provides a hands-on experience with a scale model, a relatively high viscosity fluid, and feeding behaviors.

In this outdoor, beach activity, learners use tennis balls, water balloons and other simple devices to investigate the movement of waves and currents off a sandy beach.

In this activity, groups of learners work together to create edible models of chemicals involved in autotrophic nutrition.

In this 6-7 day investigation, learners begin with an introduction to seamounts that are present in the Gulf of Alaska.

In this activity related to climate change and data analysis, learners examine temperature and precipitation data to determine if climate variations are due to El Niño.

In this activity, learners will investigate the impacts of harmful phytoplankton using NOAA's Coastal Services Center Harmful Algal Bloom Forecasting (HABF) Project data.

In this activity, learners use plastic water bottles, wood, and water to build an inexpensive and portable tool to demonstrate one atmosphere of pressure at sea level.

In this activity, learners explore the factors that tend to resist changes in pH of the ocean and why the ocean is becoming more acidic.
