8Th Grade SCIENCE: First half of BIOLOGY UNIT OBJECTIVES I Can Students will understand and the characteristics that all living things share. Students will recognize and appropriately use terms relating to biology – these terms are listed under the vocab link under “Bio Unit Resources” Students will understand the 7 level system of classification and be able to order them from broadest to most specific; they will recognize the components of an organism’s scientific name Students will be understood the process of photosynthesis and the process of cellular respiration and they will understand how the balance of these two processes keeps levels of oxygen and carbon dioxide in our atmosphere at acceptable levels. Students will understand the basic structure of a plant and an animla cell including the function of each of the following organelles: nucleus, cell membrane, ribosomes, mitochondria, cytoplasm, cell wall, chloroplasts Students will be label the organelles listed above in a diagram of the Students will be able to successfully use the microscope, calculate the overall magnification, and identify the following specimens: amoeba, paramecium, hydra, red blood cells, animal cells, plant cells and red blood cells Students will understand the relationship between structure and function and be able to explain this relationship in regard to a red blood cell. Students will understand the processes of osmosis and diffusion and will make accurate predictions about the direction in which molecules will move across the membrane if given sufficient information. Students will recognize that the cell membrane is semi-permeable and that this is one mechanism which helps the cell maintain homeostasis. I think I Can I’m not sure Can Students will understand how each of the four major blood types (A, B, AB, and O) differs from each other, and identify the possible genotype for each blood type. Students will correctly predict the success or failure of a given transfusion, using their knowledge that the body can recognize familiar proteins and accept them, while destroying unfamiliar proteins. Students will be able to prepare a slide of their own cheek cells and recognize major features of the cell under the microscope (nucleus, cytoplasm, and cell membrane) Students will understand compare and contrast bacteria and viruses, understanding that both can enter your cells and disrupt homeostasis. Students will understand how a feedback loop works and will be able to appropriately classify examples of positive vs. negative feedback; recognizing that both mechanisms are aimed at maintaining homeostasis Students will compare and contrast the processes of mitosis and meiosis and name cells formed through each process Students will recognize asexual vs. sexual reproduction and list the pros and cons of each Students will recognize karyotypes and extract information from them about the individual whose chromosomes are pictured. Students will utilize Punnet squares to successfully predict the potential genotypes and phenotypes of the offspring of a given couple. Students will understand the following patterns of inheritance: dominant, recessive and co-dominant.
