Lesson Plans
  • What's Your Type? # In this lesson, students will analyze an informational text intended to support reading in the content area.The article explains the advancements that scientists have made in understanding blood types. By reading and synthesizing the text, students will explore a real-world example of how scientific knowledge becomes more robust and durable through investigations. This lesson includes a note-taking guide, text-dependent questions, a writing prompt, answer keys, and a writing rubric.
  • Blood: The Stuff of Life # 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.

  • The Mystery of Human Blood Types # This informational text resource is intended to support reading in the content area. Blood types such as the ABO group have been inherited for at least 20 million years. 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.
  • Blood Does a Body Good # This informational text resource is intended to support reading in the content area. This article describes the components of blood (red blood cells, white blood cells, platelets, and plasma) including their functions and origins, along with a novel medical application for the rare blood-producing stem cells.

  • Hypersensitivity Type 2 and Blood Types #
    Hypersensitivity refers to excessive, undesirable reactions produced by the normal immune system. Type 2 hypersensitivity is also known as cytotoxic hypersensitivity and may affect a variety of organs and tissues. This animation relates hypersensitivity and blood types together.

  • The Blood Typing Game # This educational game is about blood types, blood typing, and blood transfusions. Your challenge is to save patients in urgent need of blood transfusions. Your job is to decide what blood type these patients belong to in order to administer safe blood transfusions. At the end you will be evaluated: if you make no mistakes at all you will get all five blood drops.
