Convection - The straw that stirs the drink.
Whether you're talking atmosphere, oceans, or mantle, one of the most important processes in Earth systems is convection. Here is one of our favorite activities for our freshmen Earth Science students at Helena High. The lab, which has two parts, allows students to see convection as it happens. The part shown in the video below focuses on helping students understand the role convection plays in causing wind. The box of water represents air.
The lab comes in a kit we purchase from WARD'S Natural Science, which includes this 2-part activity plus another activity related to ocean currents. The kit is called "Exploring Convection." To make the blue ice cubes, add 3 drops of food coloring to each empty cube mold in an ice cube tray, add water, and freeze.
I absolutely love these. They work amazing for perfect cubed ice or jello or anything for that matter. U make a lot of Kool-Aid so I like to make one flavor and freeze some and use them as ice cubes in the regular Kool-Aid so there's no more watered down Kool-Aid and the flavor mixes as it melts which I love https://www.amazon.com.
So, having selected the authors, I was ready to proceed to my next challenge, which you can read about in the next installment of the series. "All these worlds are yours:" the Appeal of Science Fiction, Part II best bearded dragon substrate
