The human foot has 26 bones.
The human hand ( including the wrist ) had 54 bones!

Earth Science Facts
One teaspoon of good soil can contain several hundred million bacteria!! Imagine that!
Oceans help spread heat from the Sun around the world.
The world’s largest ocean is the Pacific Ocean.
The Arctic is not a continent, Antarctica is a continent.
The Earth is only almost a sphere! The poles are slightly flattened.
It takes 23 hours, 56 minutes and 4 seconds for the Earth to rotate once on its axis.
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!
The average human body is made of 50 to 65 per cent water
There is more water in the atmosphere than in all of our rivers combined.
Facts about the Sun
The Sun has a diameter of 1.39 million km and is, on average, 149.6 million km from Earth.
If you flew to the Sun from the moon in a normal aeroplane, it would take about 20 years!
1 million Earths could fit inside the Sun! It’s huge!!
The diameter of Jupiter is the same as 11 Earths!
The Sun was formed from a huge cloud of dust and gas called a stellar nursery. The matter left over from the formation of the Sun formed the other planets and bodies in our solar system.
The Sun is a colossal ball of helium and hydrogen gas and is the heaviest body in our Solar System.
The immensely strong gravity of the Sun keeps objects in the solar system orbiting around it.
Some solar systems elsewhere in the universe have more than one Sun! Can you imagine a sky with 2 or 3 suns?
Our Sun is a yellow dwarf star.

The top speed of a raindrop is around 18 mph.
A moonbow is a rare nighttime rainbow!
Snowflakes can take an hour to fall from a cloud to the ground.
You can use a pine cone to predict the weather.
The eye of a storm is the calm centre of a tropical storm.
A black blizzard is dirt and dust mixed with wind.
The Beaufort Scale is a 12-point scale that measures wind. 0 is completely calm, and 12 is a strong hurricane.
The Beaufort Scale was invented by Sir Francis Beaufort.
