Updated Ideas for IB Physics IA in 2025, and Enhancing Your IA with RevisionDojo
The International Baccalaureate (IB) Physics Internal Assessment (IA) is a significant part of the Diploma Programme, accounting for 20% of the final grade. For students embarking on this crucial component of their IB journey, RevisionDojo offers a wealth of support to help them excel.
RevisionDojo provides a range of tools designed to help students navigate the IA process smoothly, from refining research questions to polishing final drafts. The platform offers guidance on structuring investigations according to IB criteria, analysing data with guided examples, and avoiding common pitfalls to improve clarity. Whether you're stuck choosing a topic or need help with the final stages of your project, RevisionDojo offers reliable, student-friendly support that aligns with the 2025 IB Physics syllabus.
One of the standout features of RevisionDojo is its expert guidance and coaching. Offering personalised IA coaching, students can receive help in choosing, designing, and refining their IA topics and experiments, which is crucial for succeeding in the IA component. The platform also utilises AI tools like Jojo AI to provide smart, tailored feedback on IA drafts, helping students improve their research, analysis, and writing quality.
In addition to these features, RevisionDojo provides structured study plans and exam preparation resources that integrate IA work with broader IB assessments. This ensures students maintain progress across subjects. The platform also offers practical advice and frameworks to reduce burnout and keep students motivated throughout their IA and overall IB journey.
The IB Physics IA tests a student's ability to design and conduct experiments, analyse data, evaluate methods and results critically, and communicate work effectively. With this in mind, choosing a clear, focused, and feasible topic is the first step towards a top-scoring Physics IA. Some potential IB Physics IA topics for 2025 include:
1. Resonance in Air Columns: Measuring the resonance frequencies of air columns of varying lengths to study standing waves and sound properties. 2. Drag Force on Different Shapes: Investigating how drag force changes with the shape or surface area of objects using a fan or water flow, and analysing the relationship between drag and velocity. 3. Thermal Conductivity of Metals: Comparing how quickly heat travels through rods of different metals using temperature sensors to measure heat flow and calculate conductivity. 4. Friction on Inclined Planes: Studying how the coefficient of friction varies with surface material and angle. 5. Measuring Refractive Index Using Snell's Law: Calculating the refractive indices of various liquids by using lasers, protractors, and measuring angles of incidence and refraction. 6. Solar Panel Efficiency at Different Angles: Identifying the optimal angle for maximum energy output by measuring a solar panel's output at various tilt angles or distances from a light source. 7. Buoyancy in Various Liquids: Studying the buoyant force for an object in liquids of different densities and relating it to Archimedes' principle. 8. Pendulum Length and Oscillation Period: Focusing on the relationship between pendulum length and period, and extending the study to include effects of amplitude or air resistance. 9. Resistance of a Wire vs. Temperature: Measuring how the resistance of a metal wire changes with temperature, applying concepts of resistivity and temperature coefficient. 10. V-I Characteristics of Non-Ohmic Devices: Investigating the voltage-current relationship for non-ohmic devices like diodes or filament bulbs.
Choosing a manageable and feasible experiment that fits your school's lab resources is essential. By combining a clear, focused topic with consistent effort, critical analysis, and support from tools like RevisionDojo, students can set themselves up for success in their IB Physics IA.
Engaging in online education through platforms like RevisionDojo can significantly enhance a student's learning experience when it comes to self-development and education, particularly for the IB Physics Internal Assessment. RevisionDojo provides valuable tools and coaching for manifesting success in the IA, including expert guidance on experiment design, personalised feedback, and the opportunity to hone research and writing skills.
