Dinosaur knowledge

Today we wrote down everything we have learnt about dinosaurs over the past 2 weeks. It was a lot!

4 legs

We learnt that...

 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. 

Dinosaur reading

Next we started reading a really hard text about dinosaurs. Miss Ashley said it was written by adults for adults, so the language is really hard, but she wasn't going to baby us and rewrite it, we just had to learn the hard adult words. 

Here are some of the new words we found from the text.

In the text it talked about BC and AD, so Miss Ashley drew a timeline to explain what it means.

Fossil and dinosaur matching

After the slideshow yesterday, today we used pictures of fossils and dinosaurs and tried to match them up. We had to look at the size and shape to match them. 

Next one person from each group had to describe the dinosaur they were looking at without showing Miss Ashley, and she had to draw it based on their description only. This is some of the drawings.

DMIC maths week 8

Here are our maths DMIC questions for this week 

Group 1

Jasmine is fundraising for her netball trip to Samoa. She has 60 tickets at $4 each. She sold half to her nana, ¼ to her uncle, ⅛ to her sister and ⅛ to her classmates. How many did each get? Who has the greatest chance of winning the prize?

 Group 2

A bakery makes 1/4  strawberry cupcakes, 1/10 vanilla cupcakes and ½ chocolate cupcakes. 

If there are 48 cupcakes altogether, how many would there be of each flavour? How many cupcakes were a different flavour? What is the chance getting a chocolate one?

Learning about fossils

Today we learnt about fossils. We looked at this powerpoint and read through it together as a class. We took notices and wrote down new words we learnt. 

Then we wrote a summary of the information from the slideshow.

Matariki maths question

Today we did an open ended maths question.

This was the question - 

For Matariki the school is going to have a hangi fundraiser. Mrs Kelly has allowed a budget of $1,000 to be spent on the ingredients. If taro is $4 per/kg, chicken is $12/kg, pumpkin is $2/kg, kumara is $5/kg etc etc. What combinations can you buy to prepare the hangi and what will your total be?

Here is what each group did.

We discussed how it was way easier to figure out what the other groups had done if they wrote the units next to the numbers (such as the second picture above this text). 

Miss Ashley showed us how we could rewrite our information but including the units so it made more sense to people.

Matariki art

Today we did a piece of art that had to do with Matariki.

First we made a mountain shape out of scrap paper and covered part of our black paper. Next we created an Aurora Borealis effect using pastels. The third step was to put on the 7 stars of Matariki, and lastly to put other small stars or shooting stars in the sky.

Here are out artworks.

Fraction problems

Today we had two DMIC problems that were about fractions.

Here is the first question - 

A bakery makes ⅛ strawberry cupcakes, ¼ vanilla cupcakes and ½ chocolate cupcakes.

If there are 50 cupcakes altogether, how many would there be of each flavour? What is the chance getting a chocolate one?

These drawings were from Janett's group. They used equal sharing to find out that 1/2 of 50 is 25, 1/4 of 50 made 2 boxes of 12 and 2 boxes of 13 (not equal!), and 1/8 of 60 wasn't equal either. Miss Ashley said to make the boxes equal, even if you have to leave some cupcakes out of it. So they found out that 1/4 of 50 was 48, which had 2 left over. They found out that 1/8 of 50 was 6, with 2 cupcakes left over there as well. 

With help from Fereti's group, we learnt that 50/2=25 was a faster way than equal sharing. Together we figured out what the number sentences/equations would be for the other cupcakes and wrote these. Then Miss Ashley challenged us to flip the divided bys into times tables and write that as well.

Then Miss Ashley changed the numbers and we had to only use times tables to figure it out. Then we had to write it two ways. It was easy now that we knew how to do it.

Here is the second question (a different group)

Jasmine is fundraising for her netball trip to Samoa. She has 60 tickets at $4 each. She sold half to her nana, ¼ to her uncle, ⅛ to her sister and ⅛ to her classmates. How many did each get? Who has the greatest chance of winning the prize?

Welsey's group shared how they solved the first two bits - 1/2 of 60 and 1/4 of 60. Some of us didn't understand why it made sense to divide by 2 when its talking about halves.

Junefia, Maria, Ana and Lily's group shared their drawing of how they tried to find 1/8 of 60, but again this wasn't a simple equation and it wasn't even. Wesley's group came close to figuring out that it was a decimal number, but wasn't sure what number. Miss Ashley helped out a little to help us figure out that it was 7.5 or 7 and a half per box.

Junefia's group wrote this. 

Earlier Lily had identified that 15 was half of 30 and this made sense because 1/4 was half of a 1/2. Miss Ashley helped everyone to realise that 1/8 was half of a 1/4, so they could have just halved 15 and solved it easily instead of drawing.
