Biology: Structure and Function of Cells

• Cell Theory: All living organisms are made up of one or more cells, the basic unit of life.
• Types of cells: Prokaryotic (simple, no nucleus) and Eukaryotic (complex, with a nucleus)
• Organelles: Specialized structures within cells that perform specific functions (e.g., nucleus, mitochondria, chloroplast).

Biology: Human Body Systems

• Circulatory system: Transports blood, oxygen, and nutrients throughout the body.
• Respiratory system: Facilitates gas exchange (oxygen in, carbon dioxide out).
• Digestive system: Breaks down food into smaller molecules for absorption.
• Excretory system: Removes metabolic waste from the body.

Biology: Plant Structure and Functions

• Photosynthesis: Process by which plants convert light energy into chemical energy (glucose).
• Transpiration: Loss of water vapor from plants through leaves.

Physics: Fundamentals of Forces

• Forces: Pushes or pulls that can change an object's motion.
• Types of forces: Gravity, friction, magnetic force, etc.
• Newton's Laws of Motion: Describe the relationship between force, mass, and motion.

Physics: Energy and Power

• Energy: The ability to do work.
• Types of energy: Kinetic (motion), potential (stored), heat (thermal), etc.
• Conservation of energy: Energy cannot be created or destroyed, only transformed from one form to another.

Physics: Waves

• Waves: Disturbances that transfer energy without transferring matter.
• Types of waves: Mechanical (need a medium), electromagnetic (travel through a vacuum).
• Applications of waves: Sound, light, radio waves, etc.

Chemistry: Basic Concepts of Matter

• Elements: Pure substances that cannot be broken down into simpler substances (e.g., gold, oxygen).
• Compounds: Substances formed by the chemical combination of two or more elements (e.g., water, salt).
• Mixtures: Combinations of substances that are not chemically combined (e.g., sand and water).

Chemistry: Chemical Reactions

• Chemical reactions: Processes involving the rearrangement of atoms and molecules.
• Types of reactions: Synthesis, decomposition, combustion, neutralization, etc.
• Balancing equations: Ensuring that the number of atoms of each element is the same on both sides of the equation.

Chemistry: Acids, Bases, and Salts

• Acids: Substances that release hydrogen ions (H+) in solution (e.g., hydrochloric acid).
• Bases: Substances that release hydroxide ions (OH-) in solution (e.g., sodium hydroxide).
• Salts: Compounds formed by the reaction of an acid with a base (e.g., sodium chloride).
• pH scale: Measures the acidity or alkalinity of a solution (0-14).

Earth Science: Structure of the Earth

• Layers of the Earth: Crust, mantle, outer core, inner core.
• Tectonic plates: Large pieces of the Earth's crust that move slowly.

Earth Science: Weather and Climate

• Atmospheric layers: Troposphere, stratosphere, mesosphere, thermosphere, exosphere.
• Climate zones: Tropical, temperate, polar, etc.

Earth Science: Natural Resources

• Renewable resources: Resources that can be replenished naturally (e.g., solar energy, wind energy).
• Non-renewable resources: Resources that cannot be replenished at a rate comparable to their consumption (e.g., fossil fuels, minerals).

Practical Skills

• Laboratory safety: Proper use of equipment, handling chemicals, wearing protective gear.
• Conducting experiments: Formulating hypotheses, designing experiments, collecting data.
• Analyzing results: Creating graphs, interpreting data, drawing conclusions.

Scientific Skills

• Scientific method: A systematic approach for investigating phenomena.
• Critical thinking: Evaluating information and evidence, identifying biases.
• Collaboration and communication: Working effectively in groups, presenting findings.

Environmental Awareness

• Biodiversity: The variety of life on Earth.
• Conservation: Protecting and managing natural resources.
• Human impact on the environment: Pollution, deforestation, climate change.
• Sustainable practices: Using resources responsibly to meet present needs without compromising future generations.
• Renewable energy sources: Energy sources that are naturally replenished (e.g., solar, wind, hydro).

Assessment Structure

• Formative assessments: Continuous assessments that provide feedback for improvement (e.g., quizzes, class participation).
• Summative assessments: Assessments that measure overall learning (e.g., mid-term exams, final exams, projects).
• Practical work: Hands-on activities to develop practical skills (e.g., laboratory assessments, report writing).

Study Tips

• Understanding: Focus on comprehending key concepts rather than memorizing isolated facts.
• Visualization: Use diagrams, flow charts, and other visual aids to simplify complex ideas.
• Practice: Work through past year exam questions to familiarize yourself with the format and difficulty level.
• Collaboration: Form study groups to discuss concepts and learn from each other.
