Students identify producers and consumers from marine ecosystems and describe the balance among them in the environments. After constructing a food chain from a marine ecosystem, they examine human activities that can upset the balance...

Two blooms of phytoplankton, instead of just one, now occur in the Arctic due to declining sea ice, which will have widespread effects on the marine life and climate. In small groups, participants build an Arctic food web with given...

A pool of brine in the deep sea can be up to four times as salty as the surrounding sea water. The deep sea ecosystem relies on chemosynthesis and the organisms that live there are often strange to us. The lesson focuses on researching...

Marine invertebrates offer us many new options for developing pharmaceutical drugs, such as w-conotoxin MVIIA, which is extracted from the cone snail and is a potent painkiller. The lesson encourages scholars to research various types of...

Students examine how food webs illustrate the ways in which organisms depend on each other for energy and nutrients, and make food webs showing the feeding relationships among organisms encountered in the Gal??pagos coastal waters.

How is a movie theater like a desert biome? Compare systems to ecosystems with a set of activities that focuses on accessing multiple intelligences and building upon knowledge. As learners discuss the ways elements of an ecosystem depend...

Students explore the nesting behavior used by sea turtles and explain how these behaviors are beneficial in the survival of a species. They discuss the advantages and disadvantages that sea turtles have be mass nesting. They identify...

You never know what you will find next in the deep sea ecosystem. So far, scientists have found items that work as anti-tumor agents, anti-inflammatory agents, agents that stop uncontrolled cell division, and much more. The lesson begins...

Students carry out an experiment to monitor diurnal fluctuations in dissolved oxygen, carbon dioxide, pH, and water temperature. They determine the CO2 and pH of the samples (and optionally, dissolved oxygen). Students complete their...

Pupils comprehend the four parameters of water quality. They perform tests for salinity, dissolved oxygen, pH and clarity or turbidity. Students comprehend why scientists and environmental managers monitor water uality and aquatic...
