Geology Unit: Reconstructing Earth's History
The first semester geology unit, titled 'External Geological Phenomena,' focuses on surface-level processes rather than internal events like volcanism or mountain formation. The opening lesson covers paleographic mapping — students travel to sedimentary regions and conduct detailed studies to reconstruct ancient environments. By analyzing fossils, rock types, and deposit patterns, researchers can determine whether an area was once ocean, desert, or forest and what climate and fauna existed there. Morocco's phosphate and coal basins serve as primary case studies. The second lesson introduces stratigraphy, the science of dating rock layers using relative and absolute methods. Relative dating compares layer sequences to establish which rocks are older based on superposition and other principles. Absolute dating assigns specific ages (e.g., 'two million years') to rocks using isotopic analysis. The unit concludes with geological cartography — learning to read geological maps, interpret their color-coding and symbols, and construct cross-sectional geological profiles that reveal underground structures.
Plant Biology: Water and Nutrient Absorption
The first biology lesson explains how plants absorb water and minerals from soil through root structures. Unlike mechanical pumps, root cells employ osmotic principles — water moves passively into the roots along concentration gradients, carrying dissolved minerals essential for plant growth. Students learn the exact anatomical locations where absorption occurs and the physical laws governing the process. The second lesson addresses gas exchange in plants, establishing a crucial distinction from animal respiration. While animals inhale oxygen and exhale carbon dioxide, plants inhale carbon dioxide and exhale oxygen during photosynthesis. However, plants simultaneously respire like animals, consuming oxygen and releasing CO2 as a parallel process. This dual mechanism explains why plants absorb atmospheric CO2 and what happens to that carbon dioxide once inside leaf cells — it enters metabolic pathways that form the basis of organic matter production. Students examine the logic and necessity of this simultaneous photosynthesis-respiration cycle.
Plant Biology: Organic Matter Synthesis and Chlorophyll Function
The third lesson in the biology unit focuses on how plants produce organic matter — the sugars, proteins, and fats found in fruits, vegetables, and grains. Three inputs combine to enable this synthesis: sunlight energy from the sun, water and minerals absorbed through roots from soil, and carbon dioxide inhaled from the atmosphere. These three elements merge in photosynthetic tissues to generate the organic compounds that humans consume for nutrition. The fourth lesson introduces chlorophyll, the green pigment that makes photosynthesis possible. Chlorophyll functions similarly to solar panels installed on modern rooftops — it captures sunlight energy and converts it into chemical energy usable by plant cells. This energy conversion occurs within leaf tissue, specifically in cells containing chlorophyll molecules. Students analogize the process: just as solar technology harnesses sunlight to generate electricity, leaf chlorophyll harnesses light to drive biochemical reactions. The final lesson examines the principal photosynthetic reactions themselves — the specific molecular mechanisms by which plants transform light, water, minerals, and CO2 into sugars and other organic molecules.
Assessment Structure and Course Coefficient
The semester evaluation system comprises four equal components, each weighted at 25 percent. Students take three formal written exams during the semester, with each exam counting as 25 percent of the final grade. The fourth 25 percent derives from a mark assigned by the teacher based on classroom behavior, notebook quality, participation, and engagement — this teacher-assigned component carries the same weight as any formal exam. The coefficient for SVT is 7, matching the coefficient for mathematics and physics, signaling that the subject is weighted equally with core quantitative disciplines. This high coefficient means poor performance in SVT directly threatens overall academic standing. Pr Ayyoub Lamsaf emphasizes that all lectures, practice exercises, sample exams, and supplementary materials are published on his channel with detailed, step-by-step explanations. He commits to updating presentation methods and visual aids annually to avoid repetition and maintain pedagogical quality.
