Because blood behaves according to certain scientific principles, trained bloodstain pattern analysts can examine the blood evidence left behind and draw conclusions as to how the blood may have been shed. From what may appear to be a random distribution of bloodstains at a crime scene, analysts can categorize the stains by gathering information from spatter patterns, transfers, voids and other marks that assist investigators in recreating the sequence of events that occurred after bloodshed. This form of physical evidence requires the analyst to recognize and interpret patterns to determine how those patterns were created.

Students are introduced to the circulatory system, the heart, and blood flow in the human body. Through guided pre-reading, during-reading and post-reading activities, students learn about the circulatory system's parts, functions and disorders, as well as engineering medical solutions. By cultivating literacy practices as presented in this lesson, students can improve their scientific and technological literacy.

Students are introduced to the challenge question, which revolves around proving that a cabinet x-ray system can produce bone mineral density images. Students work independently to generate ideas from the questions provided, then share with partners and then with the class as part of the Multiple Perspectives phase of this unit. Then, as part of the associated activity, students explore multiple websites to gather information about bone mineral density and answer worksheet questions, followed by a quiz on the material covered in the articles.

Students examine an image produced by a cabinet x-ray system to determine if it is a quality bone mineral density image. They write in their journals about what they need to know to be able to make this judgment. Students learn about what bone mineral density is, how a BMD image can be obtained, and how it is related to the x-ray field. Students examine the process used to obtain a BMD image and how this process is related to mathematics, primarily through logarithmic functions. They study the relationship between logarithms and exponents, the properties of logarithms, common and natural logarithms, solving exponential equations and Beer's law.

There are basically two types of evidence: material and physical. Material evidence is generally considered anything that can be manufactured: paint, fibers, or glass, etc. These bits of evidence can be visible or invisible. In many cases, evidence must be examined with the use of microscopes or other scientific instruments to detect and collect valuable data or information. Material evidence is also commonly known as trace evidence.

Developed for second grade. The purpose of this activity is to bring the food pyramid to life. Hang the caterpillar up in a place that is visible to all students and pass out the hand out. Break the class into six groups and assign each group a food category. Ask them to go through the magazines and find foods that fall in their assigned category and cut out the pictures. After about 10 minutes call the class back together. Each child is to pick one of the pictures that they choose to share with the class. Go around the circle and give each child a chance to explain why they cut out the picture they choose and then have them place it into the caterpillar's mouth.Biology In Elementary Schools is a Saint Michael's College student project. The teaching ideas on this page have been found, refined, and developed by students in a college-level course on the teaching of biology at the elementary level. Unless otherwise noted, the lesson plans have been tried at least once by students from our partner schools. This wiki has been established to share ideas about teaching biology in elementary schools. The motivation behind the creation of this page is twofold: 1. to provide an outlet for the teaching ideas of a group of college educators participating in a workshop-style course; 2. to provide a space where anyone else interested in this topic can place their ideas.

We take a look at the basic composition of blood. Blood is composed of liquids and solids. The solids are called the formed elements while the liquid portion is called plasma. The solids of the blood consists of red blood cells, white blood cells and platelets . The plasma is mostly water, but it does contain some plasma proteins, dissolved gases, nutrients and electrolytes.

In this video take a look at hematopoiesis (haematopoiesis), or the creation of blood. While we are still embryos the formation of blood can occur in multiple sites. After birth production primary takes place in red bone marrow.
All blood cells that are circulating derive from pluripotential hematopoietic cells also known as hematopoietic stem cells (HSCs). These stem cells can form any of the blood cells or other stem cells. Hematopoietic Growth Factor will help determine what the stem cell grows into.
There are three families that blood cells can grow up to become: 1) Erythroid cells, 2) Lymphocytes, and 3) Myelocytes.

Red Blood Cells also known as red blood cells (RBCs) or erythrocytes …
Red Blood Cells also known as red blood cells (RBCs) or erythrocytes are around 7.5μm in diameter. The average number (red blood cell count) is typically: *5,200,000 per cubic millimeter ± 300,000 men *4,700,000 per cubic millimeter ± 300,000 women
Red blood cells are made of hemoglobin. When the hemoglobin combines with oxygen it is called oxyhemoglobin, when oxygen has been released it is known as deoxyhemoglobin. The RBC initially have a nuclei during the early stages of development, they then remove the nuclei to help make room for hemoglobin.
