Science Classroom Connection

We will redo an evaluation upon the concepts and ideas that center upon homeostasis and cell transport. In the remaining time, we will synthesize a concept map with context clues that centers upon the several processes of how materials move into and out of the cell.

We will create a concept map on the several concepts and ideas that we have discussed and reinforced as well as review for our Chapter 5 test for next week. Moreover, we will review the vocabulary test. If time permits, we will outline and synthsize the process of homeostasis and cell transport as a further reinforcement.

Students are to review and study all the vocabulary concepts and ideas that center upon the processes of active and passive transport that we have been discussing and reinforcing in class for the past week and a half.

Students are to complete the study guide on active transport that centers upon the processes of endocytosis, exocytosis, and sodium-potassium pump (Na+/K+ pump); the students will explain each process through examples based upon the behavior of the different particles that are involved in each process.

We will discuss and elaborate upon the process of active transport in terms of how cells utilize such a mechanism to move substances through the cell membrane; specifically, the processes of endocytosis, exocytosis, and sodium-potassium pump will be discussed, illustrated, and elaborated upon in class.

Students are to work in groups of two or three to determine the effect of the size of molecules have on their abilities to diffuse through a membrane, simulated by a dialysis tubing/cellophane tape. Furthermore, students will analyze their findings by answering the four discussion questions given based upon their results.
