Cambridge Progression Test Stage 3 Science 2025 Paper 2

1. Life Cycles and Living Things: Chicken life cycle (egg → hatchling → chick → adult); features of birds (feathers, lay eggs); sorting living, once alive, and never lived objects; life processes like growth and reproduction.
2. Properties of Materials: Liquids flow and take container shape; magnetic testing uses magnets—materials like iron and steel are magnetic; mixtures separated by sieving, filtration, or magnets.
3. Earth, Moon, and Gravity: Moon is spherical, orbits Earth in 28 days; phases include full, crescent, half; gravity pulls objects toward Earth; standard units ensure fair comparison of force.
4. Light and Shadows: Shadows get bigger as the object moves closer to the screen; ruler used for measuring; shape and distance affect shadow size; size can also be changed by altering the light source.
5. Plants and Water Transport: Water travels up the stem to leaves; more leaves → greater water travel; investigation shows consistent upward pattern; mass of water + sugar = total mass increases.
6. Scientific Enquiry and Tools: Identifying enquiry types (e.g. research, fair test); ruler measures distance, tweezers and magnets used in separation; using data to make predictions and spot patterns.
