- Science in Our Lives II Course Outline
Science in Our Lives II Course Outline
- Unit: Digestion/Excretion
In this unit, students will review nutrition from last year, the enzyme/substrate complex, the digestive system and how food is broken down mechanically and chemically, and finally how the human body excretes liquid and gaseous waste.
- Unit: Locomotion
In this unit, students explore the musculoskeletal system and how organisms locomote. Students learn about the bones of the body, the three major types of muscles, four main joint types, exo vs. endoskeletons and various disorders with the locomotive system.
- Unit: Respiration
The ultimate goal of respiration is to make ATP! Students will learn about the parts of the respiratory system and what organisms need in order to make energy for themselves. Students also discover the dangers of smoking and what effect pneumonia and emphysema can can have on lung capacity.
- Unit: Transport/Circulation
Students in this unit will learn how materials are transported around the body and how blood works more like a "bus" than an anything else. Students focus on the topics of diffusion and osmosis under the category of passive transport and likewise learn about active transport. The parts of the blood are identified as well as the chambers of the heart through which blood travels. Pulmonary circulation is also highlighted in this unit.
*Midterm for the course follows this unit and concludes Semester one's curriculum.
- Unit: Immunity
Our bodies have an incredible defense system against disease! In this unit, students will highlight the differences among different types of pathogens as well as learn about the progressive measures our bodies take to prevent illness. The antibody/antigen interaction and passive vs. active immunity will be highlighted in this unit, as well as a discussion of vaccines and what is in a vaccine. Within this unit, students will explore a case study on the 1918 Influenza out break, they will research and present on a disease in powerpoint format and students will also watch the movie "Outbreak" (permission slip required) to see a theoretical disease become widespread and to show disease transmission precautions.
- Unit: Regulation
Regulation is how our bodies control and maintain homeostasis, our bodies internal balance. By first studying the nervous system, students will learn how the body uses electrical signals to activate neurons in the body for quick and immediate response to imbalance. The second part of the unit on regulation studies the human endocrine system, a system composed of hormones and glands that use these chemicals to maintain homeostasis but often at a slower rate.
- Unit: Reproduction
In this final unit for the year, students learn about the difference between asexual vs. sexual reproduction and examples of organisms that perform each process. Students review the topics of mitosis and meiosis in order to learn how sex cells from each gender can only contain half the chromosomal numbers of each parent in order to create a viable, living embryo. Types of fertilization and development are discussed and students also learn how to label the male and female reproductive parts.
*The Final Exam follows this unit. It is a cumulative exam that covers the entire year.
