Syllabus tag: Kenya CBC | Grade 8 Integrated Science | Strand 3.0 Force and Energy | Sub-Strand 3.2 Pressure (16 lessons)

Lesson objectives

By the end of this sub-strand, you should be able to:

• Demonstrate pressure in solids and liquids
• Identify applications of pressure in solids and liquids
• Describe the relationship between pressure, area of contact, and weight
• Appreciate the applications of pressure in solids and liquids

Summary

Pressure is how a force is spread over a surface — the same force, spread over a smaller area, produces greater pressure. This single idea explains why a knife cuts, why high heels press harder into the ground than flat shoes, and why so many everyday tools are shaped the way they are.
