We can't dig a hole through the Earth, so how do we know about the layers beneath our feet? Scholars learn about layering through hands-on exploration of common materials. They study the characteristics of each layer and apply their...

Human impacts on the environment can sometimes be difficult to measure, especially under water! An activity centered on ocean acidification gives science scholars the opportunity to examine the effects of carbon dioxide on marine life....

What's life like aboard an ocean exploration vessel? Junior oceanographers examine the important role of communication in ocean research in lesson plan two of a five-part series from NOAA. The materials introduce the class to life on...

How does a change in pH affect the ocean ecosystem? Scholars explore the idea by making an acid-base indicator in part seven of the 10-installment Discover Your Changing World series. First, they explore impacts of carbon dioxide in...

What does it mean when scientists say the earth is warming? The second video in a seven-part series explains how scientists measure the temperature of the entire Earth. It links to factors that affect climate change through discussions...

What is an air current, and what does it have to do with the sun? This is the focus of a video that explains how air currents are driven by the sun's energy to high and low pressure areas.

Earth appears blue and green now, but an interesting video covers a theory about when our planet was purple. We know the sun emits mostly green light, so why do most plants repel green light rather than absorbing it? Did purple microbes...

Ocean lovers hang ten as they watch this film about waves and currents. What causes waves? What is a current? Learn this and more from Sam as he explains why RJ was struggling to surf the gnarly waves. Have your class watch this at home...

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...

Go with the flow! The eighth installment in a 13-part series has earth science students dive in to the world's system of ocean currents. The interactive illustrates the different types and depths of currents, how wind and gravity...
