Video: The Discovery of Cells – A View of the Cell

How in the world did we get to where we are today, in terms of our knowledge of cells? Well go ahead and watch this video, and you’ll see. In it, I talk about the History of the cell theory, starting all the way from the invention of the Microscope by the dutch scientist Anton van Leeuwenhoek. See how knowledge increased from that basic discovery to all the things we know today about the structure and function of the organelles inside the cell.

Video: Atoms and Their Interactions – The Chemistry of Life

An element is a substance that cannot be broken down into smaller particles. Join me as I take you on a journey through the atom, looking at the protons, neutrons and Electrons. This journey then goes into topics like Chemical Reactions, Covalent and Ionic Bonds and the pH of different substances. By looking at the pH, we are able to determine if a substance is an acid or a base.

Video: Human Population Growth

Video: Human Population Growth

This video is from Chapter 4 in the Book “Biology: The Dynamics of Life”. It talks about population growth as it relates to Human Populations. It’s a basic introduction to the field of demographics (human population growth), and shows the 3 factors that demographers are concerned with: Growth Rate, Age Structure and Geographic distribution. Growth Rate is determined by Birth and Death rate. Age structure has to do with the proportions of a population at the different age levels, and geographic distribution deals with the topics of immigration and emigration.
