The purpose of this lesson is to teach students about blood and its components while instilling an appreciation of its importance for survival. The lesson takes a step-by-step approach to determining the "recipe" for blood while introducing students to important laboratory techniques like centrifugation and microscopy, as well as some diseases of cell types found in blood. It also highlights the importance of donating blood by explaining basic physiological concepts and the blood donation procedure. There are no formal prerequisites, but students should be comfortable with converting weight units. The only materials needed are a calculator and paper, and it would be helpful to print the downloadable color PDF files of blood smear images. During the breaks, students are asked to estimate and then calculate the amount of blood in their body, identify cell types in a blood smear, and discuss the composition of blood with their neighbor. The lesson can be completed within a 50-minute class session.

Despite how ancient blood groups are, scientists are still unclear as to their purpose. The ABO blood group, the most well-known of the blood groups, has enabled scientists to understand a link between blood groups and the immune system; discoveries over the last century suggest a link between blood groups and disease. Even with these findings, scientists are still unclear as to why such blood antigens evolved in the first place.

This tutorial will help you to understand how bone growth is different from the growth of many other organs. Although bone may appear to be rigid and lifeless it is actually living tissue that is capable of growth. Unlike soft tissues, bone cannot simply grow by adding additional cells and removing cells that are no longer necessary. The calcium laid down in bone gives the skeleton the strength and rigidity needed to protect and support the body. This rigidity means that expansion requires addition of cells on the outside and, when necessary, the removal of calcium and other materials on the inside.

This tutorial demonstrates how the structure of a signal molecule determines its function. Signal molecules can interact with either intracellular or extracellular receptors. For a signal molecule to bind with an intracellular receptor it must be able to pass through the cellular membrane. Generally signal molecules that enter the cell are nonpolar and fat soluble. These signal molecules can pass through the lipid bilayer of the cell membrane. Signals that bind with extracellular receptors are proteins or other types of molecules that cannot readily pass through the membrane.

This action reduces the chance that other nearby cells will become infected.

Blood pressure is determined by the force of the blood acting on the walls of the blood vessels. Two factors determine the size of this force. One is the volume of blood being pumped through the vessel. The other is the size of the vessels. Changes in blood pressure can be caused by either a change in the amount of blood being pumped or by a change in the size of the blood vessels. Feedback mechanisms, described in this animation, will alter heart rate and blood vessel dilation to maintain blood pressure at appropriate levels.

This Protein Purification video lesson is intended to give students some insight into the process and tools that scientists and engineers use to explore proteins. It is designed to extend the knowledge of students who are already somewhat sophisticated and who have a good understanding of basic biology. The question that motivates this lesson is, "what makes two cell types different?" and this question is posed in several ways. Such scientific reasoning raises the experimental question: how could you study just a subset of specialized proteins that distinguish one cell type from another? Two techniques useful in this regard are considered in the lesson. This video lesson will easily fit into a 50-minute class period, and prerequisites include a good understanding of cellular components (DNA vs. Protein vs. lipid) and some understanding of the physical features of proteins (charge, size etc). The simple cell model used here can be assembled in any kind of container and with any components of different solubility, density, charge etc. In-class activities during the video breaks include discussions, careful observations, and the use of a "very simple cell" model to explore two techniques of protein purification. Students and teachers can spend additional time discussing and exploring the question of "how we know what we know" since this lesson lends itself to the teaching of the process of science as well.
