The course is structured into two modules: Module 1 covered the first three chapters that taken in first course , while Module 2 includes the remaining topics
Welcome to Module 2!
This module offers a basic overview of Grade 12 Biology. It covers three chapters: the Evolution, Human body system and climate change. Although online learning follows many of the same principles as traditional methods, it’s important to recognize the unique aspects of teaching and learning in an online setting.
In online courses, the interactions between instructors, course content, and students are shaped by factors like physical and social distances, different teaching technologies, and various cognitive, emotional, and motivational challenges and opportunities.
As you progress through this module, you will be prompted to consider the following key questions:
- Do my activities and assessments help students develop the key skills and competencies outlined in the course objectives?
- Have I designed the course activities and assessments to promote academic integrity?
- Are my assessments realistic, addressing real-world problems and challenges relevant to the discipline?
- Do all activities and assessments adhere to the principles of universal design for learning?
- Do the activities, including lab work, provide opportunities to engage students and build a sense of community in the course?

- Unite 4: EvolutionEvolution is the genetic change in populations over generations, driven by mechanisms like natural selection, mutation, and genetic drift, which can lead to new species. Theories about life's origin include Special Creationism, Spontaneous Generation (disproven), Eternity of Life, Cosmozoan Theory (extraterrestrial origins), and Biochemical Origin (early chemical processes). Evolutionary theories include Lamarckism (inheritance of acquired traits), Darwinism (natural selection), and Neo-Darwinism (genetics and selection).24

- Unit 5: Human body systemBody coordination in animals involves two main systems: the nervous system and the endocrine system. Nervous System Function: Uses nerve cells to transmit electrical impulses and secrete neurotransmitters to stimulate target cells. Divisions: Central Nervous System (CNS): Comprises the brain and spinal cord. Peripheral Nervous System (PNS): Consists of nerves outside the CNS. Key Functions: Sensory Input: Receives signals from sensory receptors. Information Processing: Integrates and processes sensory input. Motor Output: Sends signals to muscles, glands, and organs. Endocrine System Function: Produces hormones transported via blood plasma to target cells. Mechanism: Target cells have specific receptors that respond to hormone concentration changes. Neurons and Their Functions Neurons: Basic units of the nervous system, specialized for responding to stimuli, conducting impulses, and releasing chemical regulators. Supporting Cells (Glial Cells): Provide support and protection for neurons. This coordination ensures that the body can respond appropriately to internal and external stimuli, maintaining overall function and balance24

- Unit 6: Climate changeClimate change refers to significant alterations in global temperatures and weather patterns over extended periods, primarily driven by human activities such as fossil fuel combustion, deforestation, and livestock farming, which increase greenhouse gas (GHG) concentrations in the atmosphere. The burning of fossil fuels, deforestation, and agriculture significantly contribute to atmospheric CO2 and other GHGs, enhancing the greenhouse effect and global warming. Greenhouse gases like CO2, methane, and nitrous oxide trap heat in the atmosphere, preventing it from escaping into space, thus raising Earth’s average temperature. The direct consequences of climate change include rising temperatures, increasing sea levels, and more frequent extreme weather events. Indirectly, it leads to increased hunger, health risks, economic crises, loss of biodiversity, and ocean acidification. Climate change disrupts habitats, threatening species and reducing agricultural productivity, which ultimately impacts food security. To mitigate these effects, various international agreements, such as the Paris Agreement, aim to limit temperature rise and promote sustainable development. Ethiopia has also taken significant steps in response to climate change, exemplified by the Green Legacy Initiative and the Grand Ethiopian Renaissance Dam, both of which illustrate the country's commitment to building a climate-resilient economy and addressing the challenges posed by climate change.18
