What do camels eat?

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.

How strong is stomach acid?

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.

What is coffee and where is it grown?

Coffee is a drink made from the roasted seeds of the coffee plant. The coffee plant originally grew in Africa, but is now grown around the world, usually in areas near the equator.

Coffee is grown in over 70 countries around the world. The top three producing countries are Brazil, Vietnam and Colombia. Coffee is grown near the equator because it needs certain weather conditions to grow well(plenty of warmth and rain).

The seeds are roasted and then ground according to the type of coffee you are making. It is then mixed with hot water to brew, although you can also soak it in cold water to make a different tasting drink.

Coffee is not recommended for children as it contains caffeine. This is something that helps adults feel more awake when they drink it!

What is a diamond?

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.

Why do bees make honey?

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.

Grandpa beekeeper passes his experience little grandson.

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!

What is a hurricane?

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.

What do giraffes eat for breakfast?

Animals usually eat the same type of food all through the day. They don’t have different meals like we do.

How do you make metal?

Metals are chemical elements which means they are part of the basic building blocks of our universe and cannot be broken down into anything simpler.

When we talk about metals we usually mean things like iron, tin or lead. These are found in rocks which are called an ore.

To make the metal you have to break down the ore to separate the metal from the rock. There are a few ways to do this, you can use heat, electricity or other chemicals, depending on the type of ore.

Once the metal is separated it can be formed into moulds, sheets, wires etc.

How do clouds form?

Clouds are formed when the water vapour in air cools down and forms droplets of water or ice. When lots of these droplets come together they form a cloud.

What is the difference between a crocodile and an alligator?

Crocodiles and alligators are two separate species of reptile, although they are closely related and look quite similar.

There are a few differences between them but the easiest way to tell the difference is by looking at their snout. A crocodile’s snout is much narrower than an alligator’s.
