Coral Bleaching: Making Our Oceans Whiter

Around 93 percent of the reefs on Australia's Great Barrier Reef have been bleached, and almost one quarter of them are now dead. Scholars research the sea temperatures, especially around the areas with coral reefs, to make connections...

A toolkit is something that has what you need to fix or make something. You just clicked on a teacher's toolkit for introducing the concept of coral bleaching in relation to climate change and changing sea temperatures. In it, you will...

Many have debated which came first, the chicken or the egg, but this lesson debates which came first, the hydrocarbons or the carbonate reef. After a discussion on deep-sea corals, scholars receive a set of questions to research and...

Global warming isn't just an issue on land; deep ocean waters are also showing troubling signs. Young scientists learn more about deep water corals and the many recent discoveries researchers have made. Then they examine data related to...

After demonstrating the use of cabbage juice as a pH indicator, have your class experiment with their own breath, exhaling into the indicator, to show that carbon dioxide is acidic. As learners work, they also watch a video about coral...

Can your breath change the acidity in a liquid? A lesson begins with a demonstration that proves it can. Then scholars perform an experiment to determine if other gases can change the pH of liquids. Finally, they research how this...

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...

Students learn what coral reefs are and about the different types of reefs, the ecology surrounding these biological playgrounds, and the human impact on them.

What drives the ocean's motion? Get your class moving toward understanding by using this video. Viewers find that thermohaline circulation is caused by the concentration gradients of temperature and salinity. Using adorable animation in...

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...
