### sense in the lessons

In science, the Earth has layers: crust, mantle, outer core (liquid metal) and inner core (solid, hotter than the Sun's surface). In PE, core strength helps balance. At school, core subjects are the main ones — English, maths and science. In everyday life, apple cores go in the compost bin. Phrases: apple core, the Earth's core, core subjects, core values, to the core (completely), core strength.
