Biology in plain sight
Plants and Life
These topics make biology feel less abstract by anchoring it in colors, growth, and changes you can see without a microscope.
Best Starting Point
Start with Why do leaves change color?
If you want one page that gives the cleanest first pass through plants and life, this is the best place to begin before branching out.
A fall-color lab that lets you change day length, cool nights, sunny afternoons, and stress to watch pigments take over a leaf canopy.
