9.0 As a result of the coordinated structures and functions of organ systems, the internal environment of the human body remains relatively stable (homeostatic) despite changes in the outside environment. As a basis for understanding this concept: a. Students know how the complementary activity of major body systems provides cells with oxygen and nutrients and removes toxic waste products such as carbon dioxide. b. Students know how the nervous system mediates communication between different parts of the body and the body's interactions with the environment. c. Students know how feedback loops in the nervous and endocrine systems regulate conditions in the body. d. Students know the functions of the nervous system and the role of neurons in transmitting electrochemical impulses. e. Students know the roles of sensory neurons, interneurons, and motor neurons in sensation, thought, and response. f. * Students know the individual functions and sites of secretion of digestive enzymes (amylases, proteases, nucleases, lipases), stomach acid, and bile salts. g. * Students know the homeostatic role of the kidneys in the removal of nitrogenous wastes and the role of the liver in blood detoxification and glucose balance. h. * Students know the cellular and molecular basis of muscle contraction, including the roles of actin, myosin, Ca+2 , and ATP. i. * Students know how hormones (including digestive, reproductive, osmoregulatory) provide internal feedback mechanisms for homeostasis at the cellular level and in whole organisms.
 
BRIEF DESCRIPTION
This lesson is designed to strengthen the student’s abilities in taking data measurements and interpreting such measurements. This activity involves an endurance test with heart rate, breath, and “effort” measurements made for a test student. Students will make inferences using the measurements they made and the information provided in the lesson.

PROCEDURES
 
Goal(s):
This lesson is designed to strengthen the student’s abilities in taking data measurements and interpreting such measurements. This activity involves an endurance test with heart rate, breath, and “effort” measurements made for a test student. Students will make inferences using the measurements they made and the information provided in the lesson.
 
Specific Objectives:
Students will be able to:
  1. Ask scientific questions.
  2. Explore the training of cross-country skiers.
  3. Investigate heart rate, breath, and effort by taking measurements and interpreting the measurements while exercising.
  4. Prepare questions to interview a cross-country skier.
 
Required Materials:
 
Anticipatory Set (Lead-in):
Ask students to raise their hand if they thought they could run for one minute without stopping. Tell students that they are going to do exactly that. Tell them that when you say go they should start running in place, after a minute say stop. After you do this activity, ask students how many of them could run for one hour without stopping. Probably fewer hands will be raised! Tell students that they are going to learn about a special group of athletes who train up to 8 hours a day doing one of the most difficult things there is, cross country skiing. Ask students to imagine what it would be like if during the entire time they were at school (all day) they would be expected to be running and working their arms at the same time. How do these athletes do it? Tell students that they will find out more by watching a short video. View The NBC Learn Video: THE INTERNAL ATHLETE: CROSS COUNTRY SKIING
 
Lesson Plan Procedure:
See student activity sheet for the procedure.
 
Closure (Reflect Anticipatory Set):
Ask students to think about what they learned in the activity about heart rate, blood flow, breathing, oxygen flow, and the process of athletic training. Tell students that athletic training isn’t just for professionals or for Olympic champions. Athletic training techniques can be used by anyone, however, it is best if it done under the guidance of an expert, with the knowledge and approval from a physician. Tell students that if they are interested in forming an athletic training club, they might discuss the idea with the physical education teacher or coach at school. If they do start a club, tell them to keep a record of their progress so that they can share it in class.
 
Assessments & notes
 
Plan for Independent Practice:
Based on the information presented in the video and in the activity, ask students to think about what it would be like to be a cross-country skier. The athlete must prepare to have an incredible amount of endurance. Arrange for an interview (either in person, online, or through email) with a cross-country skier. A source might be found through the following site: http://www.xcski.org. Ask students to work in groups of four to think of ten meaningful questions they could ask during their interview. When they complete this activity, have the groups share their questions with the class so that the questions could be narrowed down to 10-20 questions for the entire class to ask. Ask students to prioritize their questions so that even if they only have a short amount of time they can ask what is most important to them.
 
Assessment Based on Objectives:
See part two of student activity sheet for assessment questions.
 
Possible Connections to Other Subjects:
Social Studies/History: Have students research the history of cross-country skiing. They should include important statistics about distance and time of the athletes over the years. They can prepare a PowerPoint presentation showing the history of cross-country skiing and include photos of well-known athletes.

Health/Physical Education: Students may work with a coach and/or a doctor to create a personal plan for athletic training. Students can share their plan with the class and provide regular updates as to how they are doing with the plan.
