Earth's Layers
Know that Earth has layers — a thin outer crust, a thick hot mantle, and a core at the centre — and that the inside of the Earth is extremely hot
Lesson
Set out your lesson
“Earth's Layers means naming Earth’s main layers from outside to inside. We will practise once together, then check a fresh example.”
Bring to the table
- Earth layers diagram or paper circles (crust, mantle, core)
- Labels for crust, mantle, outer core, inner core if used
Extra for the adult
Worked example. The crust is the thin outer layer we live on. The mantle is beneath it. The core is toward the centre of Earth.
Optional challenge. For Earth's Layers, add mantle and core in order.
What to notice. Keep one parent note: layers named outside-in; support used. This session samples Earth structure, not mastery of geology.

Check understanding
- Name Earth's three main layers: crust, mantle, and core
- Explain that the crust is thin compared to the other layers
- State that Earth's interior is extremely hot — hot enough to melt rock
“If your child cracks open a hard-boiled egg, can they compare it to Earth and name the three layers — crust on the outside, mantle in the middle, and core at the centre?”
