Create a cairn
Cairns are man-made towers of natural stones, usually built as a landmark or a memorial.
- Gather a range of flat rocks, pebbles, sticks and twigs in different sizes, and stack them in order, with the largest at the bottom and the smallest at the top.
- Can you make changes to the structure of your cairn, such as using a foundation of lots of smaller stones, and see if it still stands?
