مراجعة ليلة الامتحان في مادة العلوم المتكاملة - حل اهم الاسئلة | اولي ثانوي ترم تاني بكالوريا 2026

Hello to all the first-year secondary school champions (the Flood Batch)! This is the final review for the integrated science curriculum for the second semester of 2026. With you is Dr. Mohamed El-Tohamy. In this video, we'll continue working through our question booklet (starting with question 101) and summarize the most important concepts from the curriculum so you can enter the exam confidently and achieve top marks, God willing. This review is specifically designed to be your comprehensive and practical guide for the night before the exam. We'll apply practical exercises to questions covering all branches of the subject (geology, chemistry, biology, environment, and technology), with a simple and detailed explanation of why each answer was chosen and the others were excluded. Lecture notes link: https://drive.google.com/drive/folder... Review topics covered in this video: Geology and Earth Sciences: Differentiating between source and reservoir rocks (petroleum traps), petroleum distillation (bitumen), mineral properties (hardness, specific gravity of galena, and cleavage), tectonic movements and the San Andreas Fault, the Earth's internal temperature gradient, the outer core, and the magnetic field. Chemistry and Materials Properties: Classification of nanomaterials (one-dimensional, two-dimensional, and three-dimensional), endothermic and exothermic reactions and how to calculate them, uranium nuclear fission, and the radius of the hydrogen atom. Biology (Human and Plant Body): The mechanism of nerve impulse transmission and synaptic regions, the function of blood vessels (capillaries, aorta), kidney functions, filtration, and urine formation, the role of the liver and bile in fat digestion, phloem structure in plants, and water transport forces (cohesion, adhesion, and tension). Environment and Biosystems: Analysis of food webs (desert and aquatic), energy transfer and loss in the energy pyramid, the role of bacteria in nutrient recycling, and vital processes such as cellular respiration, ATP synthesis, and photosynthesis. Technological and Environmental Applications: Ultrasound-assisted perineural nerve ablation for treating high blood pressure, the difference between natural and artificial kidneys, geothermal energy generation, and the purpose of the high-speed electric train project in Egypt. Get ready! Have your paper, pen, and our booklet ready, focus on each question, and always remember the secret we agreed on: "Mastery." Let's master the integrated sciences and not be afraid of any question! Your support matters to us: Subscribe to the channel and turn on notifications to receive the rest of the exam review sessions. If you liked the explanation, please give it a thumbs up and share the video with your friends so everyone can benefit. Leave a kind comment or ask any questions you have in the comments, and I'll answer them. Wishing you all the best of luck!
