What is being observed is the rate of photosynthesis determined by how much oxygen is being produced. When enough oxygen has been produced in…

But even more amazing is scientific literacy and why these demonstrations work the way that they do. It’s essential to match those concepts with clear, accurate concrete examples. Dying the leaves of celery or carnations is…
An Introduction to Genetics through Botany
Our Botany Block offered the perfect opportunity for an introduction to genetics with the work of Friar Gregor Mendel. Mendel is the person that bred several generations of pea plants to discover the basic understanding of genetics. In this book Gregor Mendel: The Friar Who Grew Peas, the story of Gregor Mendel is told and…
