Moon Rock
Around 2,000 samples of moon rock, weighing almost 400kg (880 Ib), have been brought back to Earth. By studying these rocks, scientists have built up a picture of the composition and history of the Moon. Some rocks, for example, were formed from molten lava.

Ancient Pines
The North American bristlecone pines (Pinus longaeva) are the world's oldest living trees. Some surviving example took root more than 6,000 years ago! Scientists study the width of growth rings in their wood to see how the world's climate has changed.

Birds without Wings
The brown kiwi (Apteryx australis) from New Zealand is one of the several birds that have lost the ability to fly. Its wings are tiny, and its feathers are hair like. Unusually for a bird, the kiwi has a good sense of smell, which it uses to find food.
