Naturalist Charles Darwin made observations, conducted experiments, and kept detailed notebooks of his findings throughout his life. He was regularly transfixed by his observations of the natural world, whether in his early collecting days, during his legendary voyage on the Beagle, or on his daily walks in later life through the British countryside. This article offers two scientific investigations to deepen students’ understandings of not only how science operates, but how Darwin in particular, approached analysis of the natural world.
