Grade: 10th Science SCI.III.2.5 Strand III: Using Scientific Knowledge in Life Science Standard 2: Organization of Living Things - All students will use classification systems to describe groups of living things, investigate and explain how living things obtain and use energy; and analyze how parts of living things are adapted to carry out specific functions. Benchmark 5: Describe technology used in the prevention, diagnosis, and treatment of diseases and explain its function in terms of human body processes. Constructing and Reflecting: SCI.I.1.4 – Gather and synthesize information from books and other sources of information SCI.I.1.5 – Discuss topics in groups by making clear presentations, restating or summarizing what others have said, asking for clarification or elaboration, taking alternative perspectives, and defending a position. SCI.II.1.3 – Show how common themes of science, mathematics and technology apply in real world contexts. SCI.II.1.5 – Explain the social and economic advantages and risks of new technology.

Based on this information the students will develop health maintenance and disease prevention activities which use technology. The students will explain how these activities and technologies can be used in their daily lives. Corresponds to standard I.1.4 ¾ e.g. exercise program- heart monitor, exercise equipment ¾ controlled diets – cholesterol screening, food supplements ¾ good life choices – sun screen, genetically Altered food ¾ medical evaluations – blood pressure screening, glucose monitor Students will present their findings to the class. As a class, students will rank/order these activities from the most important to the least important. Each student will write a plan to maintain a healthy lifestyle that includes activities and technologies that he or she will use. • Disease Detectives lessons from Science Olympiad Assessment Optional Assessment • You are a physician’s assistant. Identify the condition of a patient who needs to change an unhealthy lifestyle. Make a list of at least 3 healthy behaviors and their benefits to be given to the patient. Also, include any technology used by the patient or practitioner. Criteria Apprent. Basic Meets Exceeds Completeness of list Identifies condition and zero to one healthy behaviors with appropriate technology. Identifies condition and two healthy behaviors with appropriate technology. Identifies condition and three healthy behaviors with appropriate technology. Identifies condition and four or more healthy behaviors with appropriate technology. Completeness of dialogue Conversation is incomplete and/or not believable. Conversation has main ideas but no details. It is not quite believable. Conversation has main ideas and some details. It is believable. Conversation has main ideas, many details, and is very believable. Teacher Notes: Focus Question: What activities and technologies support a healthy lifestyle? Investigate and explain how living things obtain and use energy. The relationship between life and energy is complex. While the generalization that living things need energy to survive is satisfactory at one level of understanding, it fails to convey the crucial role energy plays in all aspects of life, from the molecular to the population level. At the elementary level students can compare and contrast food, energy and environmental needs of selected organisms, such as beans, corn or aquarium life. In the middle and high school, the focus is more specific on the concept that plants make and store food. Scientists speak of the flow of energy through the environment. Almost all life on the earth is sustained by energy from the sun. This energy is transformed and moved from location to location, but doesn't disappear. Plants capture the sun's energy and use it to produce energy rich organic molecules that we call food. The food molecules then serve as energy sources for plants and ultimately animals. In animals, organic food molecules are chemically broken down and carried through the circulatory system to cells, cytoplasm, and eventually to mitochondria. This is, most often the site of final energy release through the process known as cellular respiration. The chemical process of photosynthesis occurs at the cellular level and is capable of converting light energy into molecular energy. Animals are dependent on plants for this first important step in the flow of energy. In plants, light energy is captured by chloroplasts or chlorophyll and is converted to chemical energy through the making of organic food molecules when water and carbon dioxide are chemically combined to make sugar and oxygen. These sugars (organic compounds) formed in photosynthesis are used for the plant's metabolic processes and maybe ultimately be used as food for animals. The chemical process of respiration is also cellular. Cellular respiration releases stored molecular energy so the energy can be used for other life processes. Both plants and animals respire. The acquisition and use of energy by living things is a very abstract idea for students at all levels. Students tend to develop a vague and very broad definition of energy that is inconsistent with the scientific definition. This imprecise definition interferes with the acquisitions of the biological understanding of energy and its importance in a living system.
