India and Greek

 Q: (What is the main difference between india and greek foods?)

A: India uses spice almost every time and in Greece they use herbs for their flavour


Q: (Why would the southern parts of India be noted for making fish dishes?)

A: Because they are closer to the biggest ocean in the world the pacific ocean. Also they are a part of more than 3 of the most other biggest oceans. They are the United States, the United states, Atlantic and indian.


Q: (Why would many herbs grow wild in the greek mountains during spring?)

A: In the mountain it's steep and people don’t walk in that bit so when that bit is not disturbed it and plus the temperature is good for the herbs.


Q: (Why does olive oil hold the flavors together)

A: It would hold and observe the herbs together. 

Q: (Main points and bigger idea why are some breads used for mopping up a meal?)

A: Because it helps you finish your food faster and its even good by itself


Q: (How would you describe the pastry used to make spanakopita?)

A:Its thick crust on the top and bottom but not side and crispy


Q: (Do you prefer foods that are flavoured with spices or those that are flavoured with herbs?)

A:Some people prefer spicy and some prefer herbs


Kelp Forest

 Q.Where do kelp plants live?

A.Shallow cool water


Q.How could the relationship between kelp, sea otters and sea urchins be described?

A.Sea otters feed on sea urchins and sea urchins feed on kelp


Q.Which part of the kelp plant is similar to a tree trunk?

A.Stipe


Q.When the sea otter populations increased, why did the sea urchin populations decrease?

A.Because the otters were protected so then there were more sea otters that feed on sea urchins that's why their population decreased


Q.How could pollution destroy kelp forest?

A.The water would get warmer and the kelp needs cold water, If the water is filled with rubbish and sediment the kelp can’t get the sunlight that it needs to grow.


Q. Look at the photograph on page 6, Why do you think the top layer of kelp is called the canopy?

A.Because its blocking the sunlight from going in the water.


Q.what do you think should be done to help protect kelp forest?

A.Stop littering in the water and stop polluting.

Zebrafish explanation

 Zebrafish text: https://drive.google.com/file/d/1AfZGT3Fw8xj7Mh_A0OxjRzK_qOIYHrko/view


New words: .

  • Anatomy- study of the body.

  • Post-fertilization  - after the boy part and girl part come together to make a baby (when the cells combine)

  • Himalayas - mountain range that separates China and India

  • Embryo - a group of cells that turn into a baby or egg

  • Genetic - relating to your DNA

  • Himalayas - A country that has a lot of Mountains

  • Ganges  - a long river in India

  • Organs - body parts

  • Juvenile - child/teenager

  •   Sections - slices  

  • Stained with dyes - putting different coloured liquids onto it so you can see different parts 

  • Coronal -  cutting in half vertically E.g. separating the front and the back 

  • Transverse -   cutting in half horizontally, E.g. cutting the head off the body

  •  Sagittal - cutting in half  vertically - E.g. cutting the left side away from the right side

Hope -  Zebrafish is transparent and they live in Ganges river in the wild, in India where they have fresh water. Scientists study the zebrafish because they are transparent so the scientists see inside it. Zebrafish is 2.5cm to 4cm long, Embryo is the egg of the zebrafish and has three layers which are single cell,yolk and chorion. After the scientists breed about a hundred or thousands of zebrafish they kill them and look at them under a microscope to study them. It takes 2 to 3 days for an egg to hatch, the zebrafish lifespan is 2 to 7 years.

These are different kinds of cuts.

  • Coronal -  cutting in half vertically E.g. separating the front and the back 

  • Transverse -   cutting in half horizontally, E.g. cutting the head off the body

  •  Sagittal - cutting in half  vertically - E.g. cutting the left side away from the right side.

Scientists kill the zebrafish at different ages(hour/days post fertilization). Scientists take photos of the different stages of how the organs grow. They use different kinds of dye to see different kinds of body parts and they take pictures of it to see the difference between zebrafish. 

                                               

This is a 48 year old coronal, the big round part is going to                This is a 48 transverse and the two big                  Be the body part                                                                                   circles are going to be the eyes

Early human evolution explanation

 The evolution of humans can be easily seen through their Latin translations; Hominins (man), Homo Habilis (able/handy man), Homo erectus (standing man), Homo neanderthalensis and Homo Sapien (wise man). Over millions of years these creatures changed and developed. Charles Darwin’s theory of evolution explains how we got to be the modern humans we are today.Interbreeding Among Early Hominins | IFLScience

Theory of evolution

Charles Darwin’s ‘theory of evolution’ was made famous in 1859 when he published his book called ‘The Origin of Species’. In this book, he talked about the idea that all living things originated from one common ancestor and evolved over millions and millions of years. He also introduced the idea of ‘natural selection’. Natural selection means that animals/organisms with desirable traits (E.g. things about them that helped them to survive, like their size, camouflage, long neck, etc) would survive and pass their traits onto their children. The ones with undesirable traits (e.g. too small, too slow, couldn’t hide, couldn’t fight back) were eaten and their traits were not passed on. His ideas were accepted by scientists around the world as he had been studying different species around the world for decades.

First land organisms

The first organisms to venture onto land (apart from plants) was around 30 million years Ago. A fish called coelacanth was one of the first to venture onto land - into a shallow marine environment. Scientists think it was either looking for food, avoiding predators or laying eggs in the shallow waters. It had to develop a stronger rib cage in order to support its body weight out of water (as in water all things are more buoyant). Over time, they also evolved lungs so they could breathe, and their fins became more boney and became strong legs which helped them move.  Years after the first amphibian-like animals came along the first one had fins and years after it had half fins and legs after a lot more years it has all legs.

HomininsA hominid skull fossil reveals the face of Lucy's possible ...

Hominins are the earliest version of a human that we know of. For about 6 to 5 million years ago hominids/ancestors have been known to live on planet earth located in Africa. They were around 130cm tall and weighed about 35kg. Hominins used to draw things in caves.  They eat hard items or food such as seeds and nuts. Hominins are closely related to humans or homosapin. And the first hominins that step foot on Africa or New Zealand 3 million years ago. And the olds hominins live for 5.8 million year. They were bipedal. They had grasp too. And they have family. Hominins evolved and turned into a human. What's in a Name? Hominid Versus Hominin | Science | Smithsonian ...

Homo Habilis

Homo Habilis lived 2 million years ago. The person the first discovered homo habilis was Mark Leakly. Homo Habilis were flexible and versatile. They were also to eat tough food like leaves and woody plants and they also eat meat by scavenging from animal carcasses. Homo Habilis were the first kind of human to make/use tools. Their family is Hominidae and live in small groups. Homo Habilis inhabited parts of Sub Saharan Africa from roughly 2.4 to 1.5 million years ago. They also have several teeth in the lower jaw and have bipedal with no grasping feet; limiting them to a life on the ground. They are the most ancient representative of the human genus and their brain ranged in size from 550 cm cubed to 687 cm cubed. The tools made by Homo Habilis were made from volcanic rock cobbles.

Homo erectus

Homo erectus had Larger brains then the homohabilis. They were the first to leave Africa around 1.5 million years ago, then the homo erectus went into Europe/Asia. Their hands used to look like a foot but then it changed into a hand, then they had Dexterous Fingers which means they can use them. Homo erectus is a Bipedal which means they stand on two long legs. By 800,000 years ago, they used fire to cook food. Homo erectus ate meat and crisp root vegetables, they ate small animals and ate animals many times larger than their own body size, such as elephants, rhinos, buffalo, and giraffes, whereas chimpanzees. Homo erectus is an extinct species of archaic humans from the pleistocene. Homo erectus Height is 1.4 to 1.8m. Their brain size is 550-1,250 cm. They weigh about 41 kg to 65 kg. The homo erectus fossils are found in Africa, Asia and perhaps Europe. Their appearance is human-like body proportions and upright stance, a protruding brow ridge, large face and no chin.

Homo neanderthalensis

Homo neanderthalensis lived in southern Europe and Asia. They are commonly called Neanderthals, named after a region in Germany where fossils were found. They existed around 1,000,000 years ago and are often depicted hunting ice age animals such as mammoths. Their height was around 1.7m.  Neanderthals lived alongside early modern humans for at least part of their existence. They had large front teeth; scientists think they used these like a third hand when preparing food and other materials. They lived peacefully and had children with other types of humans. Homo neanderthalensis looked after their sick and buried their dead. They were mammals. Neanderthals could make their own spears and flint handaxes. They used their tools to kill large mammals and eat them. Their skulls were like the same size as homo sapiens; they had a large nose, strong brow bridge. Scientists think that their stocky bodies and wide open nostrils helped them survive colder climates.

Homo sapiens 

Homo sapiens is the scientific name for modern humans. It is the only extant homo species (not extinct). Homo sapiens first migrated from Africa 70-50,000 years ago and lived in Southern Asia and Europe. Males were around 1.7m tall and females around 1.6m tall. They ate meat gathered by killing animals, plants and fungi. They lived at the same time as some Neanderthals, and lived peacefully alongside them, even interbreeding with them. Some modern humans have upto 2% Neanderthal DNA in them.

Over time, humans grew bigger and taller, travelled across continents, learnt to make and use tools/weapons, learnt to cook food, and grew bigger brains.
