Animal kingdom

New words from animal kingdom reading
Monday’s reading

Organism - a living thing
Vertebrate - has a spine
Invertebrate - has no spine
Taxonomy - a way to group things
Diverse - a big range
Amphibians -
Heterotrophic - means they must find and eat food
Primates (apes, monkeys)
Rodents (rats, squirrels)
Cetaceans (dolphins, whales)
Marsupials (kangaroos, koalas)
Monotremes (egg laying mammals like the platypus)
Autotrophic - make their own food by photosynthesis
Photosynthesis - how plants make their own food
Vascular - uses roots to absorb water
Nonvascular - uses the whole plant to absorb water
Decompose, decomposition - to break down
Non-flowering - no flowers
Thermophiles - (root word is thermo which is about temperature)

Big ideas from the reading
All living things are called organisms.
They are organised into 6 groups called kingdoms. Each group has certain characteristics that each organism must have.
Animals
Can move on their own
Are heterotrophic (can’t make their own food)
Must eat to survive
Vertebrates and invertebrates
Plants
They are Autotrophic (they make their own food)
Some are vascular and nonvascular.
If a plant has seeds or fruit, it is a flowering plant.
Eubacteria
Are made up of just one cell. They are everywhere. Some bacteria are good and some are bad.
Bacteria called decomposers break down dead plants and anacteria.
Archaebacteria
Can survive where no other organism can live.
Thermophiles, methanogens and halophiles
Fungi
Say it fun guy
Mushrooms are a fungi
They are heterotrophic (can’a make their own food)
Use enzymes to break down food

Protista
Are related to either plants, animals or fungi (one of them, not related to all of them at the same time)

Room 7
Dinosaur knowledge
Prior Knowledge
In 2 weeks, we learnt that...
  • Animal
  • Predator
  • Dino is the root word
  • ‘Saurs’ means something
  • Species 
  • Extinct 
  • Huge
  • Large bones
  • Long necks
  • Eggs 
  • Sharp teeth
  • Long tails
  • Eat people
  • Different kinds
  • Spikes
  • Horns
  • Mammals
  • 4 legs
  • Bipedal means 2 feet and quadruped means 4 feet. Some dinosaurs are bipedal and some are quadrupeds. Some can change between the two stances. They are sturdy.
  • Theropod is a 3 clawed dinosaurs
  • Dinosaurs are warm-blooded, which means their blood temperature is always the same
  • Carnivore means a meat eater
  • Herbivore means a plant eater
  • Omnivore means it can eat plants and meat
  • Some dinosaurs are huge and some are small. Typically, huge dinosaurs were sluggish (slow). 
  • Dinosaurs died out 66 million years ago. They started existed 230 million years. 
  • They died because of an extinction event, most people think this was because a meteor hit the Earth. 
  • Dinosaurs legs go out the bottom of their hip bones, whereas reptiles bones go to the side of their hips. Reptiles do not have an extra hole in their skull, but dinosaurs do. 
  • Mary Anning found lots of fossils on a cliffside in England in the 19th century. She was born in 1799 and died in 1847. She survived a lightning strike as a baby. In 1824 she found the first fossil.

  • Non-avian dinosaurs are dinosaurs that are not birds. Avian means birds.
  • Metabolism means how fast or slow your body converts food into energy
  • Diverse means a big range
  • Modifications means changes. Dinosaurs have modifications such as spikes, armour, horns or crests. 
  • Clade means family.
  • Lineage means ancestors/descendants 
  • Paleontologists are scientists that study ancient things including dinosaurs
  • There are 4 main groups of dinosaurs; theropods, sauropods, ankylosaurus and pterosaurs.
  • Titanoboa was top of the food chain after the dinosaurs died. It killed people by constricting people. It spent most of its time in the water because it was super heavy. It was 13m long, as big as a bus. 
  • Hominins existed when 7-6 million years ago, the first humans to walk on 2 feet. 
  • People did not exist when dinosaurs existed.


  • Adaptation is something that changes over time. 
  • Ecology - how animals relate to each other
  • Fossils are made when dinosaurs die and their bones get trapped in rock or mud. The bones break down over time but leave a mould, which is filled with rock. This becomes the fossil. 
  • Dinosaurs sometimes eat each other. 
  • There were 3 periods of time that have dinosaurs. This is called the ‘age of dinosaurs’ also known as the ‘Mesozoic Era’; Triassic period, Jurassic period, and Cretaceous period. 
  • Then there were 3 more periods in time, “Age of mammals”, also known as ‘Cenozoic Era’; Paleogene Period, Neogene period and  Quaternary period.
  • Dinosaur fossils have been found on every continent, including Antarctica.
  • Joan Wiffen found the first dinosaur fossil (a theropods tailbone) in NZ in 1975, in Hawkes Bay. She died in 2009. 
  • Dinosaurs laid eggs and they lived in family groups.
