Join us for an engaging and hands-on exploration of the natural world in our class, **Education At Your Fingertips**. Designed for inquisitive minds, this course combines the fascinating realms of Biology, Natural Science, and Geography. Students will embark on a journey to uncover the interconnectedness of life and the environments that sustain it. #### Course Topics Include: **1. The Wonders of Biology:** - **Cell Biology:** Understand the fundamental unit of life. Explore cell structure and function, and the significance of cellular processes such as photosynthesis and cellular respiration. - **Genetics:** Dive into the world of heredity. Learn about DNA, genes, genetic variation, and the principles of inheritance, including basic Mendelian genetics. - **Ecology:** Study the relationships between organisms and their environments. Topics will include ecosystems, food webs, biodiversity, and the impact of human activity on nature. **2. Exploring Natural Sciences:** - **Physical Science Basics:** An overview of the physical sciences, including an introduction to matter, energy, and the fundamental laws of physics. - **Earth Sciences:** Investigate geological processes, the rock cycle, weather patterns, and the structure of the Earth's atmosphere. Understand how these processes shape our planet. - **Environmental Science:** Explore pressing environmental issues such as climate change, pollution, and conservation efforts. Discuss sustainable practices and how we can protect our natural resources. **3. Geography:** - **Physical Geography:** Examine the Earth's physical features, including landforms, climate, ecosystems, and biomes. Understand how these elements interact to shape environments. - **Human Geography:** Study the relationship between people and their environments. Explore topics like urbanization, cultural landscapes, and the impact of human activities on natural resources. - **Map Skills and Geography Tools:** Learn how to read and create maps, use GPS technology, and interpret geographical data. Develop skills to analyze spatial relationships and patterns in the environment. Throughout **Science in Your Fingertips**, students will engage in hands-on experiments, collaborative projects, and field investigations designed to foster scientific inquiry and critical thinking. We will utilize a variety of resources, including interactive simulations, documentaries, and field trips, to enhance our learning experience. By the end of this course, students will have a richer understanding of the biological, physical, and geographical principles that shape our world and will be empowered to think critically about the challenges facing our environment today. Join us as we make science tangible, relevant, and fun! **Note:** Course materials will be provided, but students are encouraged to bring their curiosity and enthusiasm for discovery.

Cell Biology is a fundamental topic in both the IGCSE and CIE AS/A Level Biology curricula. It focuses on the structure, function, and processesof cells, the basic units of life. Here's a breakdown of the content at each level: --- IGCSE Biology (0610/0970) At the IGCSE level, cell biology introduces foundational concepts about cells, their structures, and processes: 1. Cell Structure and Organization -The Cell as the Basic Unit of Life: - Differences between plant and animal cells. - Identification and functions of cell structures (organelles): - Cell membrane: Controls the movement of substances. - Cytoplasm: Site of metabolic reactions. - Nucleus: Contains DNA and controls cell activities. - Mitochondria: Site of aerobic respiration. - Chloroplasts (plant cells): Site of photosynthesis. - Vacuole: Contains cell sap (large in plants). - Cell wall(plant cells): Provides structure and support. - Use of a light microscope to observe cells. 2. Specialization of Cells. - Specialized cells and their adaptations: - Red blood cells, nerve cells, root hair cells, ciliated cells, sperm cells, etc. - Understanding tissues, organs, and organ systems. 3. Movement of Substances - Processes for the movement of substances across membranes: - Diffusion: Movement of particles from high to low concentration. - Osmosis: Movement of water through a selectively permeable membrane. - Active transport: Movement of substances against a concentration gradient using energy. 4. Enzymes - Enzymes as biological catalysts and their role in cell processes. - Factors affecting enzyme activity: temperature, pH, substrate concentration. CIE AS and A Level Biology (9700) At the AS/A Level, cell biology expands significantly, focusing on advanced concepts, cellular processes, and microscopy: 1. Cell Structure - Prokaryotic vs. Eukaryotic Cells: - Prokaryotes (bacteria) lack a nucleus and membrane-bound organelles. - Eukaryotes (plants, animals, fungi, and protists) have a nucleus and organelles. - Structure and Function of Organelles: - Nucleus: Contains chromatin and nucleolus. - Mitochondria: Site of ATP production (aerobic respiration). - Ribosomes: Site of protein synthesis. - Endoplasmic Reticulum (ER): - Rough ER: Protein transport and modification. - Smooth ER: Lipid synthesis. - Golgi Apparatus: Modification, packaging, and transport of proteins. - Lysosomes: Contain enzymes for digestion. - Chloroplasts (plants): Site of photosynthesis. - Cell membrane: Phospholipid bilayer and fluid mosaic model. - Cell wall: Found in plants, fungi, and prokaryotes. - Microscopy: - Light microscopes and electron microscopes (TEM and SEM). - Calculations: magnification and actual size 2. Cell Membranes and Transport - Structure of the phospholipid bilayer (fluid mosaic model). - Functions of proteins in the membrane: carriers, channels, and receptors. - Transport mechanisms: - Diffusion, facilitated diffusion, osmosis, and active transport. - Endocytosis and exocytosis (bulk transport). 3. Cell Division - Mitosis: - Stages of mitosis: prophase, metaphase, anaphase, and telophase. - Importance of mitosis for growth, repair, and asexual reproduction. - Meiosis: -Production of gametes. - Significance in genetic variation through crossing over and independent assortment. 4. Cell Communication and Enzymes - Role of enzymes in metabolism (anabolic and catabolic reactions). - Cell signaling: How cells communicate via hormones and receptors. 5. Viruses - Virus structure and replication as non-cellular entities (e.g., HIV and influenza). - Summary - At the IGCSE level, cell biology focuses on basic cell structures, specialized cells, diffusion, osmosis, and enzyme functions. - At the AS/A Level, it covers advanced topics such as organelle structure, cell division, membrane transport, microscopy, and the differences between prokaryotic and eukaryotic cells.

Cambridge International GCSE: Biology / Chemistry / Physics / Mathematics (Tokyo)
Benson
After my first lesson with Benson, i have felt more confidence in my skills with chemistry than i have in many years. Where I previously felt very subconscious and unable to answer questions, i have now been able to answer difficult IB exams questions with ease. Benson provided me a safe and comfortable environment which has left me excited for my next class at school to show what i have learned with a fresh confidence! I highly recommend this tutor to anyone who struggles with confidence in both themselves and their subjects.

Raef
Superb experience with Raef. I asked for his help to prepare a math assessment test with an enormous lack of basis but he accepted the challenge. I found out a nice teacher who is not afraid of explaining and repeating if necessary. I did enjoy his method with the whiteboard, it feels like you are in the same place and can interact on the same exercise. Either in English or french he will certainly be able to help you. He is super kind and flexible, I definitively recommend his services.

Singing technique and repertoire for all ages and abilities. (Lansdowne)
Kyra
Kyra is a fantastic teacher! She is incredibly knowledgeable and kind, and made me feel comfortable from the first lesson. I have been singing for 8 years and have never felt better (vocally) since my lessons with Kyra. Looking forward to many more lessons in the future!
