Life Science Grades 7-8 Print Credit Recovery
Life comes in all shapes, sizes, and colors. Life exists in a simple one-celled- organism such as a bacteria to a highly complex form of life such as a human being. Whatever form it takes, each organism has to face the same challenges: the challenge of getting energy, the challenge of reproducing, and the challenge of maintaining structure. This course looks at these challenges: What is the chemical process that allows each organism to get the necessary energy and why carbon is so important? What is the organization of the cell and its structures? How are mitosis and meiosis different? What are dominant and recessive traits. The lessons includes classification of species, photosynthesis, and cellular reproduction, DNA, RNA and man's relationship to the environment.
This study material is designed to provide students with an understanding of the pattern of life of plants and animals and their interrelationships with the environment.
After reading the required text and completing the exercises found in the Study Guide, you will be able to:
· describe how plants build food from water, air and sun;
· describe how animals use plants for food;
· specify the importance of the elements in air to animals and plants;
· discuss how life continues via survival of the fittest;
· list ways to alleviate the problems of imbalances in nature by practicing conservation;
· demonstrate an appreciation for nature and an understanding of nature's importance to maintaining our quality of life.
