Introduction to Rocks - Lesson Plan

The "Introduction to Rocks" lesson plan is part of the Year 3 Chemistry curriculum and is designed to impart foundational knowledge about rocks to primary school pupils. This lesson is a scientific exploration into the classification and characteristics of different rock types, adhering to the National Curriculum guidelines. Pupils will delve into the study of geology, learning to compare and group various rocks based on their appearance and simple physical properties. Preceding lessons on everyday materials from Year 1 and Year 2 set the stage for this more detailed investigation. The lesson aims to enable pupils to describe the features of different rocks and classify them accordingly, using skills such as observing over time, pattern seeking, and identifying, classifying, and grouping, with a focus on ensuring fair testing and research using secondary resources.

During the lesson, pupils will handle real rock samples, including sedimentary, metamorphic, and igneous rocks, and use hand lenses to closely examine their characteristics. They will be encouraged to discuss and write down their observations, working collaboratively in groups. The activities are designed to help pupils identify the three main rock categories—sedimentary, metamorphic, and igneous—and understand the processes by which they are formed, such as the cooling and solidification of molten rock for igneous rocks, or the compression of broken-down rock pieces to form sedimentary rocks. Health and safety considerations are highlighted, with reminders to handle sharp rock samples carefully and wash hands after the activity. The lesson concludes with a plenary session where pupils assess their understanding of rock types and their characteristics, reinforcing the key concepts introduced in the lesson.
