The study of physics in 7th grade is an exciting stage, because it is here that students first get acquainted with this basic science. The main feature is that it is an introduction to the world of physical phenomena. Students move from abstract concepts to specific ones, observing the world around them through the prism of physical laws. At this stage, the main thing is the formation of basic ideas about movement, interaction, force, pressure and other basic concepts.

The key element is the practical component: conducting simple experiments, experiments and solving problems that help to consolidate the theory. Instead of complex mathematical formulas, the emphasis is on a qualitative understanding of processes. It is important that the child learns to see physics in everyday life: why an apple falls, how a plane flies or why a ship is floating. Thus, studying physics in 7th grade is not just a memorandumfacts, and the formation of a new way of thinking and understanding the world.
