Expansion, Contraction & Design: How Materials Respond to Temperature Changes
Materials expand when heated and contract when cooled, a phenomenon that has important implications for engineering, construction, and everyday life. Understanding expansion and contraction helps Grade 9 students in Alberta explore how temperature affects materials and how designers accommodate these changes in structures and products. Thermal Expansion occurs when particles in a substance gain energy and move more rapidly as temperature increases. This causes the material to take up more spac
