The Universe Worksheet | KS3 Physics and Astronomy

This engaging and informative worksheet introduces Key Stage 3 students to the structure and scale of the Universe, combining planetary science, gravitational forces, and astronomical concepts in a 45-minute activity. It is ideal for classroom use, homework, or revision and supports calculator use for relevant numerical questions.

The worksheet covers the Solar System, moons, galaxies, and the Milky Way, as well as the difference between rocky and gas planets. Students apply knowledge of gravitational force using the formula F=mg, calculate weight on different planets, and interpret how gravity changes with mass and distance. Additional questions explore the concept of light years, Earth’s orbit, seasons, and key celestial events like solstices and equinoxes.

This resource builds confidence in both conceptual understanding and scientific reasoning. A full answer sheet is included, making it suitable for self-marking, guided correction, or homework review. It aligns well with the KS3 science curriculum and lays foundational knowledge for future GCSE studies in physics and astronomy.

Key learning areas include planetary order and classification, gravitational strength, light year calculations, orbital dynamics, seasonal changes, and basic cosmology.

KS3/4 Physics Worksheet Bundle

This bundle provides printable PDF worksheets for most major topics encountered by students in KS3/early KS4 Physics, covering key topics such as: * Energy * Momentum * Speed, Distance and Time * Units of Measure * Specific Heat Capacity * Magnets and Electromagnets * Basic Series Circuits and Power * The Universe * Density and Volume * Hooke's Law (and Elasticity) * Turning Moments * Optics (Reflection, Refraction, Lenses) * Pressure * Light and Sound Waves * + Free definitions resource The worksheets are all designed to take between 40-55 minutes (though individual sheets vary) and all include a mixture of short and long calculation, short and long answer and exam style problems for in class work, revision, homework or assessment. Answers are provided as an additional sheet at the end of each PDF - shorter, easier questions have bottom line solutions provided however longer, more involved questions have solutions and guidance. The sheets start simple however progress in difficulty throughout, testing all abilities. The sheets are suitable for early KS4 and 'challenge' questions are provided to test those students who need something a bit more involved to keep them busy. Some sheets are listed as KS3 instead of KS3/4 - these sheets may cover a topic at a KS3 level only, and may not be relevant for the complexity added for GCSE, though this is only the case for 2 of the worksheets in the bundle. All of the worksheets provided in this bundle can be bought **individually** in my shop however this bundle gives you access to all of them nearly 30% off!
