Tree Rings tell many Tales
Examining ancient trees helps scientists get an amazing picture of Earth’s life, for trees are a record of their life time.

Preparing for Winter
Autumn was coming to an end. All the insects and animals were working very hard to stock their larders with enough food to last them the winter.

Therefore, everyone was working hard, all except Mr Grasshopper. He loved autumn. Autumn was a time when the leaves changed colour....
