The Dam Quiz
Workers whose job was to climb down canyon walls on ropes to remove loose and weakened rocks along the canyon walls where the dam walls would join.
ABSTRACT: ANNALS OF SCIENCE about climate change and the ocean… Writer describes the work of Victoria Fabry, an oceanographer who studies tiny marine organisms called pterapods. As part of her research, she noted that increased carbon dioxide (CO2) in the water caused the pterapod shells to dissolve… Writer describes the large quantities of carbon dioxide that have been added to the atmosphere since the start of the industrial revolution by the burning of fossil fuels. Gasses from the atmosphere are absorbed by the ocean. Nearly half of all the carbon dioxide that humans have emitted since the start of the nineteenth century has been absorbed by the sea.

Back to previous page No, don't take us literally! Humans cannot drink saline water. But, saline water can be made into freshwater, which everyone needs everyday.
Desalination: Drink a cup of seawater? - US Geological Survey
In this activity students will review the major topics associated with abrupt climate change. Each student will then choose one of the concepts that they feel is important to understand, research the topic and then become an expert and teach others in the class on this topic.

Coral Reefs Coral reefs are among the most diverse ecosystems on the planet, with species estimates ranging into the millions and new creatures discovered each year [1].
For this activity students will use maps to estimate how the human population may be affected by the decline of corals reefs worldwide due to climate change.

The three Working Groups full reports and the Synthesis Report, the final part of the AR4, are available online (see here below). Hardcopies of the Summaries for Policymakers + Technical Summaries are available for free in the 6 UN official languages upon request to the IPCC Secretariat. Hardcopies of the full reports can be purchased from Cambridge University Press .
IPCC - Intergovernmental Panel on Climate Change
Students will raise Artemia (Brine shrimp) in the classroom in a variety of pH levels. As the ocean's acidity increases it is thought that plankton that form shells will not be able to do so.

Corals don't only occur in warm, sun-drenched, tropical seas; some species are found at depths of three miles or more in cold, dark waters throughout the world's oceans. Some cold-water coral reefs are home to more than 1,300 species of animals, a diversity rivaling some better known tropical coral reefs. Until now, scientists believed bottom trawling – a commercial fishing method in which vessels drag large, heavily weighted nets across the bottom – to be the greatest threat to cold-water corals.In this activity students will evaluate their understanding of the carbon cycle in the oceans while reading different articles.

Ocean Acidification Carbon has a complex life cycle: its released by living organisms as part of respiration, converted into sugar by plants and algae, and absorbed by the oceans where it is used in the marine food web – only to be given off in respiration again! Unfortunately, human activities during the past two centuries have begun to tip natural carbon balances between the atmosphere and the marine environment.

IPCC who? On February 2, 2007 a major report from the Intergovernmental Panel on Climate Change (IPCC) stated that climate change observed over the last several decades is “very likely” due to human impacts on the environment [1].
