Using cabbage juice as a pH indicator, future scientists explore the effect of increasing carbon dioxide on the pH of the ocean and relate it to the health of coral reefs. Ideal for an earth or environmental sciences course, this lesson...

The fascinating video "Changing Planet: Fresh Water in the Arctic," introduces your oceanographers to the world's gyres. They learn that melting sea ice is making the gyres larger, and that the changes could, in turn, contribute even...

As an anticipatory set, young environmental technicians watch a video about how ocean temperatures seem to be changing along with the global climate. They perform a laboratory demonstration with the purpose of observing what happens to...

Science learners simulate what happens when ice breaks up and floats on water and how increased pressure on ice causes it to melt faster. They view a clip from the movie, The Day After Tomorrow, and relate their lab activities to what...

Students study how the ocean stabilizes our planet's climates and how global warming is becoming a threat to this fine balance.  In this climate change activity, students identify that fossil fuel emissions are responsible for...

A video and laboratory investigation are highlights to this instructional activity on acidification of ocean water due to increased atmospheric carbon dioxide. Using bromothymol blue (BTB) as an indicator, pupils analyze the amount of...

Students explore the carbon cycle. In this carbon cycle lesson, students discuss the four main reservoirs where carbon is stored and then discover the process through which each reservoir absorbs and releases CO2. This lesson includes a...

Are our oceans really suffering due to the choices humans make? The sixth and final installment in the volume of activities challenges research groups to tackle one of six major topics that impact ocean health. After getting to the...

Temperature rises and land disappears! Through a lab exploration, learners understand the effect of temperature increase on water similar to the effect of global warming on our oceans. As they heat the water in a flask, they measure the...

When we think of ocean exploration, many of us have visions of sunken pirate ships full of treasure or mysterious creatures of the deep. What really motivates deep-sea investigation? The first in a series of diverse six-part lessons...

Save the oceans! The 22nd installment of a 23-part NOAA Enrichment in Marine sciences and Oceanography (NEMO) program focuses on laws and marine policy. Pupils take part in an activity investigating fisheries stock data.

Students examine the impact of a major climate change in the Arctic Ocean on the rest of the world. They use the Internet to research the Arctic region and the wildlife that lives there.

How does carbon dioxide affect the world's oceans? The final installment in a series of six lessons has pupils research ocean acidification, then conduct an experiment to witness the delicate balance that exists in our seas. Materials...

Examine the benefits of chemical defense mechanisms. Organisms in oceans use chemicals to ward off predators. Duplicate this adaptation using a hands-on experiment in which you ward off your predators (your pupils) with some...

Can you imagine Washington DC and London as close neighbors occupying the same continent? Learners will be fascinated as they step back in time and discover the evolution of the earth's continents and oceans from 4.5 billion...

Students investigate the role of temperature and salinity in determining seawater density. They use a Temperature-Salinity Diagram to examine the effects of mixing on density.

Students identify and experiment with dendrochronology (the study of tree rings to answer ecological questions about the recent past) and come up with conclusions as to what possible climatic conditions might affect tree growth in their...

Students use their prior knowledge to being their examination of the water cycle. In groups, they complete an experiment in which they can see water evaporating and coming back to the ground. They discover the ocean's water evaporates...

Students read information about global warming and make their own greenhouse. For this global warming lesson, students read several pages of global warming and climate information. Students then make their own greenhouse and answer...

Learners practice analyzing images, maps and graphs from Internet-based educational resources. They explore the correlation between sea surface temperature and coral bleaching. Students comprehend that coral reefs are collections of tiny...

Students observe temperature differences of water and air in sunlight and darkness. They determine that the sun warms the Earth's surface, which controls global currents and climate, keeping the earth habitable. They discover water and...

High schoolers will identify the factors that contribute to erosion and weathering. They will start by differentiating between chemical and mechanical weathering. They then apply what they learned by playing the online jeopardy game. Key...

How is sea coral like a thermometer? Part three of a six-part series from NOAA describes how oceanographers can use coral growth to estimate water temperature over time. Life science pupils manipulate data to determine the age of corals...

Students sample goodies from an unseen ocean floor and try to accurately describe their composition. This simulation helps students explain the limitations of sampling and the problem of obtaining representative samples of sea floor...
