The Orca/killer whale
The killer whale or Orca is a huge sea mammal that is at the top of the marine food chain. Their scientific name is Orcinus orca. Despite its name the killer whale is actually a dolphin. Like all wild animals the killer whale has a special diet and behaviours that make them unique.
Like many animals, the Orca eats a wide variety of foods that are contained in its diet. Being a carnivore means this animal only eats meat. Some of the Orcas food in its diet are seals, dugongs, fish and sea birds. This diet is very much the same as the great white shark which is a very strong sea mammal but not strong enough to kill a killer whale.
The Orca is top of the food chain so that means that there is nothing in the ocean to kill a killer whale. There are a few things that will try to kill one though. These animals are probably the bravest sea animals and they are the great white shark and the leopard seal. So overall the killer whale has very few try hard predators.
The female Orca can usually breed until the age of forty. Male killer whales in the wild may not fully reproduce until they are much older, stronger and able to compete with other males. Females can only have one live young every five years. Surprisingly the killer whale is not on the list of endangered species even though they only have one baby every five years.
The killer whales appearance is a black and white layer of skin which they use to camouflage like military planes. The largest killer whale ever recorded was nine point eight meters in length and weighed ten thousand kilos. The male are also bigger than the female in length. The killer whale also have pectoral flippers, dorsal fins, tail flukes and girth.
Overall the killer whale or Orca is the king of the sea. Did you know that killer whales gets it whale name because it can tackle large animals? They can also not smell. I hope this information can get put to good use and I hope you learned something.

The wind was howling like wolf in a full moon. The humongous rocks make it look like a human is an ant. The grass sways like a dancing wacky man. The water changing colour makes it look like a collage art. The waves devour everything on the beach.

Why the sky is blue
How old were you when you asked your parents “ why the sky is blue?” Most people could say that the sky isn't really blue but can’t explain why. Here at Halsey Drive I am going to tell you the scientific explanation of why the sky is blue.
Firstly to know that the sky is really blue is that sunlight looks white but it is actually made up of all the colours of the rainbow. Just like sound light also travels in waves. The blue waves are short and bumpy and red is long and not as bumpy, however blue light is scattered every where because blue has shorter waves than the other colours. The other colours- red, orange and yellow- also bounce off the molecules but blue scatters the most and that is why the sky is blue.
On the sunlights way to Earth the waves travel in straight lines unless something gets in its way to reflect bend or scatter when it is coming down passing through the atmosphere. It then passes through lots of little tiny oxygen and nitrogen molecules that are made up in the atmosphere and float around in the sky. When it gets closer to the horizon the sky fades to a very light blue or even a white, this is because the light has traveled very far.
Overall the sky is blue because all the molecules in the air have spread the sun’s light when it travels down to earth. As light travels down to earth in blue waves which are shorter and that means it gets distributed a lot more and this is what makes the sky blue.
