Glow With the Flow

Emerging biochemists more fully understand the flow of energy in ecosystems as they explore the laws of thermodynamics and relate them to energy transfer in food chains. They also investigate heat loss from the human body and how...

Soil scientists gain experience with an infiltrometer can to determine the infiltration rates at different locations on campus. If you are using the entire unit, the class has already analyzed water flow and soil types, so they should...

The living environment, from the interior of a cell to the complex relationships among populations, are queried in this final examination. Learners look at air pollution maps, diagrams of cells, population graphs, and drawing of cells....

How does one organism get its energy? What is the main source of energy in an ecosystem? How does the flow of energy affect different types of ecosystems? Answer these questions with a fill-in-the-blank worksheet. 

More than 100,000 commercial flights take off every day, but how do the planes fly? Veritasium presents a video explaining the way wings work. It opens with the common misconception, then introduces two seemingly conflicting...

It's amazing how easy it is to forget that every second of our lives we are being pushed on by an uncountable number air molecules. Explore with your class the concept of air pressure and how it affects our bodies, the earth's...

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...

When you have to flow, you have to flow. The lesson introduces class members to microfluidic devices and their uses in medicine. They watch a short video on how the diameter affects the rate of flow. The worksheet has individuals...

Junior engineers examine aspect ration in airplane wings. Using the length and width of two differetn wings, they calculate the aspect ratios and compare drag rankings. An engineering or space science class would benefit from this...

Too often we think of air as empty space- but compared to a vacuum, air is actually pretty heavy. Dan Quinn describes the fundamentals of air pressure and explains how it affects our bodies, the weather, and the universe at large. [3:19]
