Join Ocean Portal Editor-in-Chief Emily Frost and museum educators from the National Museum of Natural History as they guide you through the Ocean Portal website, exploring a multitude of digital assets including vetted scientific information, interactive content, and education resources.

For most of us, the term “marine organism” brings to mind images of fishes, coral reefs, marine mammals, or other animals that are easy to see with the naked eye. Yet, 98% of the biomass in Earth’s ocean and most of its biological activity is provided by marine microbes— organisms that are exceedingly small, less than a few thousandths of a millimeter. Scientists conducted a global survey of marine microbes species in 2014 called Ocean Sampling Day. This lesson plan includes a marine microbe activity and a simulation of the activities conducted in the 2014 survey.

Along the East Coast of the United States, two diseases can cause significant damage to growing oysters and in some cases even kill them. In this lesson plan, students will use data to determine whether water temperature, oyster size, or time of planting determines whether a young oyster becomes ill with disease.  

The veined rapa whelk is an invader in Chesapeake waters. These predatory snails eat ecologically and economically important shellfish that are native to the bay. In this lesson, students will learn about invasive species and predict where the invasive rapa whelk will live within the bay. A discussion of invasive species impacts on native ecosystems will follow. 

Much like rising and setting sun has an impact on life on Earth, the cycle of the moon can change plant and animals behavior. In this lesson plan, students will discuss how the lunar cycle affects living organisms and how this might occur. They will also design experiments that could figure out whether the lunar cycle affects a specific behavior.

This group of lesson plans focuses on primary production in the ocean via photosynthesizers, like plankton and algae. Students will learn what factors limit primary productivity in the ocean and about other ways ocean organisms produce energy (i.e. chemosynthesis). 

Learn how scientists collect field data by being a scientist yourself! By studying a specific ecosystem, students learn how different scientists work together, what kinds of data scientists record, and experience the scientific process through observation and data collection.

How does an ecosystem recover from a major one-time insult such as an oil spill? As you will learn from this Discovery Story, the answer is not simple. It isn't easy to determine whether a particular area of shoreline has recovered from oil during a spill, or how to expect it to look when it has.

Students will be able to list the various adaptations that enable deep-sea fishes to survive; explain how bioluminescence helps deep-sea fish respond to food predator and reproductive pressures in their environments; explore how the structure of an appendage helps determine and utilize its function; describe how deepwater organisms respond to their dark environment.
