Camels are herbivores, which means they eat plants or vegetation.
Camels are specially adapted to live in the desert, where vegetation is scarce. What does grow in the desert can be prickly and tough due to the lack of water. Camels have leathery mouths which allow them to eat thorny twigs, as well as leaves, stems, shoots and fruit.
Their mouths aren’t the only part that is especially adapted to desert living.

Stomach (or gastric) acid is a mixture of hydrochloric acid, potassium chloride and sodium chloride. An acid’s strength is measured on the pH scale. The range of acid strength goes from 0(strongest) to 6(weakest). Stomach acid measures between 1 and 3 on this scale, making it quite a strong acid.
The reason the acid doesn’t burn our insides is because the stomach produces mucus to line itself and protect it from the acid. We need acid in our stomachs as this starts the process of breaking our food down(digestion), so it can be absorbed by our bodies.
After the food leaves the stomach and enters the next part of your digestive system, the pancreas releases a bicarbonate which helps to neutralise, or weaken, the acid so it doesn’t damage your insides.
Fireworks were invented in 7th century China. The Chinese people believed they would ward off evil spirits and bring happiness and good luck.
Nowadays fireworks are used all around the world to celebrate various events. In the United Kingdom they are traditionally used on Bonfire Night, the 5th of November, to celebrate the failed Gunpowder Plot of 1605.
The first animal to orbit the Earth was a dog called Laika. She was launched into space aboard Sputnik 2 in 1957. She was a stray dog from the streets of Moscow in Russia. In the early days of space flight animals were used to test the safety of the technology, before humans tried it.
A diamond is a precious stone and is the hardest naturally occurring material known. It is made from carbon which can come in different forms depending on how its atoms are arranged. A diamond has a lattice structure in which the atoms are bonded together very strongly.
Diamonds are formed deep underground in the earth’s mantle, around a 100 miles down. They are formed under high pressure and temperatures and can take 1 to 3 billion years to form. They are brought closer to the surface by deep volcanic eruptions and are then mined by people.
Bees make honey as a way of storing food for themselves. They need to do this for when their usual food sources are in short supply. Flowering plants are more abundant in spring and summer, so bees make honey during this time to see them through the winter, when there are much fewer flowers.
Honey is an ideal way to store their food supply, as it doesn’t go bad. This is because it has a high sugar content, which also means it provides a lot of energy for the busy bees!
A hurricane is a large storm characterised by very strong winds. If a tropical cyclone has winds over 74mph(119km/h) and it forms in the Atlantic Ocean, it is known as a hurricane. There are 5 categories of hurricane numbered 1 to 5. The most severe category 5 hurricanes can have winds up to 200mph(320km/h). The hurricane develops around an area of low pressure(the eye) and the winds rotate in an anti clockwise direction around this point. This is what they look like from space.
A hurricane is specific to the area around the USA. A tropical storm formed in the Indian Ocean is called a cyclone, and one formed in the Western Pacific Ocean is called a typhoon.

The science of weather prediction or forecasting is called meteorology. A person who predicts the weather is a meteorologist.
A meteorologist will collect data from a range of sources to show what the current weather conditions are. They then predict what will happen based on what has happened in the past, when the conditions were the same or similar.
Among the type of data collected is air pressure, temperature, wind speed and direction. This data is collected by weather stations which are dotted around the country.
