Concept Questions on Gases

Open this lesson by demonstrating the production of acidic carbon dioxide gas by activated yeast. Emerging ecologists then experiment with seashells to discover the effect of ocean acidification on shelled marine organisms. They measure...

Here is the first of four poignant lessons on how humans and oceans interact, even if people live far from the coast. This particular lesson also examines studies that are taking place in Antarctica of how climate change is affecting the...

Groups explore illumination with NASA's Lighting Environment Test Facility (LETF) as a context. Using the TI-Nspire app, groups determine the lux equation that models their simulation. They then use the lux equation to solve problems...

What effects do temperature and carbon dioxide levels have on the zooplankton of Antarctica? This concluding lesson in a short unit on climate change and the ocean helps environmental scientists answer these questions. After learning...

A well-written lesson plan, second in a series of four, gets high schoolers exploring how the Antarctic food web is impacted by climate change and the associated melting of polar ice sheets. It begins with a PowerPoint presentation about...

Exactly what causes the the pain you feel when diving to the deep end of a pool? Find out with this short video that explores the physical laws governing the behavior of gases and the ways they affect marine life and scuba divers that...

How can something we can't see be so powerful? Gas molecules make an impact! This video explains their properties: 1. Gas particles always move in a straight line. 2. They are too small to occupy any volume individually. 3. When gas...

Raising the global temperature by two degrees may not seem like much, but the impact this would have on the planet is amazing. Follow along with this short video as it examines how even a small change to a system can turn its regular,...

It's easy to take for granted the the importance of electricity in modern society, and even easier to overlook the environmental cost that is paid for all that energy. Watch as this video explores the detrimental impact burning coal has...

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...
