Facts about the Rainforests
The Amazon rainforest covers 7 million square kilometres ( 5% of the Earth’s total land area ).
In the rainforest, there are only 2 seasons, the rainy season and the dry season. Even in the dry season, it rains almost every day.
Around one-quarter of the ingredients in modern medicines come from rainforest plants.
There are 4 major layers of the rainforest. Each differs and has unique characteristics because they receive different amounts of air, light and water.
Trees in the rainforest can grow up to 60 metres tall.
Water Science Facts
Did you know water is the only natural substance to exist in three physical states at temperatures naturally occurring on Earth?
Water freezes faster when it’s warm, not cold!
