Classifying Organisms

New words from reading
 Tuesday 23rd July 2019


Big idea: within each kingdom there are more different groups that classify animals. 


  • Prokaryotes - a name of a kingdom 
  • Etc means etcetera
  • Interbreed - when two different animals have babies together


Mnemonics help us remember hard things, for example NEVER EAT SOGGY WEETBIX helps us remember North East South West. 


This is the mnemonic i learnt to help me remember the order:
Keep ponds clean or fish get sick.


Kingdom
Phylum
Class
Order 
Family
Genus

Room 7 Dinosaur knowledge Prior Knowledge

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 Cretasous 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. Room 7 Dinosaur knowledge Prior Knowledge In 2 weeks, we learnt that...
