Blood Clotting Study
The ability of blood to coagulate prevents excessive bleeding from minor wounds. This process is essential for survival. Using actual samples of students’ blood, students observe the formation of fibrin threads under the microscope, measure clotting times and bleeding times, and observe the effects of calcium on blood clotting.

Kit #1-32Basic Blood TypingStudents test their own blood to determine which of the four major human blood types it is: A, B, AB, or O. (Note: Blood types determined by this activity may not always be accurate.) They learn that different blood types result from the presence or absence of specific molecules in the blood called agglutinins...

Kit #1-SSimulated Blood Typing
This activity allows students to “practice” blood typing while avoiding having to draw blood. Instead they learn the procedures and principles of blood typing based on a realistic model. In this activity, the agglutination of red blood cells by the corresponding antibody is simulated by chemical precipitation. Without spilling a drop of...

Kit #1A-32Rh Blood Typing
The significance of the Rh factor becomes clear as students type their own blood to determine if they are Rh Positive or Rh Negative. In the first part of this activity, students determine their own Rh blood type. This is done by typing their blood and observing tissue incompatibility. Next, they mix a blood...

Kit #1BBlood Smear
This three-step experiment provides students with a clear understanding of lab techniques and an opportunity for self discovery. Students draw samples of their own blood with individualized sterile lancets and prepare smears by applying Wright's stain. Using a microscope, they examine the smears to identify different cell types (erythrocytes, polymorphonuclears, eosinophiles, basophiles, lymphocytes...
