Students will report their findings to the class. In the Field – pH and Alkalinity Students will read the article on page 172. Students will research water quality and testing issues for the Gulf Coast in the wake of hurricanes Katrina and Rita. Students will prepare a report that explains the water-quality problems caused by the hurricanes and what solutions were developed by the crisis management team. Health Science Students will list foods that contain high amounts of protein, such as meats, fish, dairy products, and beans. Students are to determine why is important to have an adequate amount of protein for a healthy diet and why one group of compounds have so many different functions Polymer Students will write a paragraph that includes the following: (a) brief explanation of a polymer, (b) a description of the four major classes of organic compounds found in living things, (c) a description of how theses organic compounds are used by the human body. Creative Writing

For example, one student can play the nucleus, directing the other students who are playing organelles to do specific tasks. Encourage students dramatize what might happen if the nucleus became damaged or removed. Isotonic vs Hypotonic Students will write a poem about a cell that is first in an isotonic solution and then in a hypotonic solutions. The cell may be either a plant or animal cell. Sports Drinks Students will research the benefits of sports electrolyte solutions that athletes drink during or after exercise instead of water. Students will write an argument to answer the following question – Is there any danger in consuming sports drinks even when you have not exercised? of Solutions Students will construct a graphic organizer that defines and illustrates the three types of solutions: Hypotonic Hypertonic Isotonic New Discoveries Students will research a new discovery relating to the cell or its structures. Students should include the name of the scientist(s) responsible for the
TOOLBOX Unit 2.1 Principles of Evolution and Classification Plans They’re More Evolved That Way Examining How the Latest Theories on Human Evolution Might Impact Historical Understanding Evolution: To collect, analyze, and interpret information about objects in order to classify them into a cladogram. Unit 2.1 Principles of Evolution and Classification Background for Teachers An Introduction to Evolution-- Biological evolution, simply put, is descent with modification. Genetic variation is the raw material of evolution. Without genetic variation, a population cannot evolve in response to changing environmental variables and, as a result, may face an increased risk of extinction.
