My favorite science experience is climbing the tallest redwoods and using high-tech instruments to understand how these giants of the plant world make a living. A part of what we’ve learned is that gravity interacts with the hydraulic system of the trees to cause increasing water stress in the uppermost parts of the crown as the trees grow taller. So, their height growth slows, but they still gain girth—just like people!
