How does blood clot? Students examine their own blood to better understand the clotting process. Students discover their own clotting times studying coagulation rates and bleeding times. They observe the formation of fibrin threads in clotting, and study the effects of calcium on blood clotting. Individualized worksheets and sterile components make this a highly motivational lab activity. MICROSCOPES ARE NEEDED.
