Project Lead the Way is a national, not-for-profit educational program that assists high-school students in developing strong backgrounds in science and engineering. The following is the link to Project Lead the Way online: http://www.pltw.org/Biomedical/biomedical.cfm Teachers are required to train for the courses Project Lead the Way offers. I have spent a total of 8 weeks at IUPUI training to teach Principles of Biomedical Science (PBS), Human Body Systems (HBS), Medical Interventions (MI) and Biomedical Innovations (BI). During my training, I completed the labs, projects and activities that my students will be doing in class this year. This class will be rigorous and, challenging, fascinating and fun. The curriculum motivates most students to work hard, learn to work well with others, improve higher-level thinking skills and it ultimately results in a deep understanding of how the human body works, how to properly perform lab techniques, what biomed careers are available and how medical interventions can help.

Activity 4.4.2 Mind Over Muscle-LAB 1. Logger Pro Problem 4.4.4 Train a Champion-PROJECT 1. An athlete training for an intense physical event needs to consider diet, exercise, hydration, and injury prevention as well as track his or her progress and modify the plan to meet the demands of exercise. 15 Lesson 5.1: The Skin-6% Activity 5.1.1 Under Your Skin-PROJECT 1. The skin is a dynamic organ that functions in protection, temperature regulation, sensation, excretion, and absorption in the human body. Activity 5.1.2 Burn Unit 1. Burn damage to skin can impact numerous body functions and body systems. Activity 5.1.3 Hurts So Good 1. Both the body’s ability to sense pain and to suppress pain help protect the human body from injury and death. calculate an ankle brachial index (ABI). Interpret the ankle brachial index (ABI) to determine possible blockages in blood vessels. Key term quiz Recognize that the body uses high energy molecules such as creatine phosphate, glycogen, and glucose to supply ATP to working muscle. Recognize that muscle fatigue occurs with prolonged or repetitive use of a muscle group. Describe ways in which an athlete can prepare his or her body for the stress of an athletic event. Illustrate the body’s response to the stages of exercise. Design an experiment to test the effect of feedback, coaching, or competition on muscle fatigue. Interpret EMG and grip strength data to assess muscle fatigue. Apply knowledge of power and movement in the body to design a comprehensive training plan for an athlete. Test Describe the structure and function of the two main layers and the accessory organs of the skin. Explain how different degrees of burns damage layers of the skin.
