Yesterday 3 people from the Blake Organisation came to Tangaroa and presented a talk about ocean life and how humans have slowly polluted the ocean life.
In maths, I have been learning about angles and analogue clocks for hero maths, We have to do area and perimeter and I’ll give you an example, so the area of a square that has 10 length and 10 width would be 100 because you’re just timesing the 10 and 10. And the perimeter of a square that is 10 by 10 would be 40 since there’s 4 sides of a 2d square. The shape above is a shape split up into 3 sections, I calculated that area a would be 18cm² because 6 x 3 = 18, I thought area b was 12 because 4 x 3 = 12 and I thought area c was 10 because 2 x 5 = 10 and if I add all those numbers together I get my answer, so 18 + 12 = 30 + 10 = 40 so 40cm² would be my answer.
Say if shape a had 8 cm by 1 cm and shape b has 4 cm and 3 cm and shape c had 5 cm and 2 cm it would be 30cm² because shape a would be 8 because 8 x 1 = 8 and shape b is 12 because 4 x 3 = 12 and shape c would be 10 since 5 x 2 = 10, add those all together and it equals 30cm² and that’s how you work out the area of a shape.
Last week we had to make a Harakeke Ecosystem Project, we had to do like a life cycle of Harakeke, I made a simple idea on how it works So the water and nutrients from the soil, carbon dioxide (co²,) from the air, and warmth and get light from the sun. Thank you for reading this.
Kelly from Project Jonah came to talk with us about whales and dolphins, normally if you saw a dolphin in the south island (Where we are right now) it would most likely be a Common Dolphin We learnt that a fully grown Blue Whale can grow up to 30 metres (80 to 90 feet) Humpback whales are 15 metres (49 feet) the Pilot whale is 4 – 6 metres (13 – 20 feet) and the Common Dolphin (Hectors Dolphin) is 2.2 to 2.7 metres (7.2 – 8.9 feet.)
There’s these two stories she told us and one of them was when a humpback whale saved a marine biologist diver that fell in the water not knowing that a Tiger Shark was circling around her and the Humpback Whale pushed her up on the surface to try and save her. The other story I couldn’t get a video of it because it was copyright but it was a seal stuck on a small piece of ice unable to swim to the bigger ice because there were killer whales (Orcas) surrounding the ice about to eat the poor seal but the Humpback whale flipped over so you could see the white part on his belly, let the seal climb onto the Humpback’s belly, and he escorted that seal to the other ice where the Killer Whale’s (Orcas) couldn’t get him. That reminds me of mass stranding, so mass stranding is like when a Humpback whale since they’re so nice when they get stranded on the beach, they call for their friends to help him/her and they all come to help but then all of them get stuck and 650 whales washed up on the beach, they only could save around half of them.
The Stranding happened in 1918.
This is the story when a little girl was coming back from school and saw a lump on the beach, she asked her mum if they could go to the beach, and they found this massive whale stranded on the beach, they remembered the phone number and that phone number was 0800 4 WHALE. They knew the rules about how to treat a stranded whale, Number 1: put a light clear blanket like white and don’t put it over it’s blow hole or its face so you don’t attract the heat with a black cover, Number 2. put water into a bucket and pour it on the whale, Number 3: Avoid fins and back tail because they can severely injure you, because they have the strongest muscle in the animal kingdom inside their back tail.
If you want to know if it’s safe to go in the water you can tell if it’s a shark, a dolphin or a whale the way to do that is, watch its tail and if it moves up and down it’s a dolphin or a whale and if it goes side to side it means it’s a shark or a fish.
2 days ago (Tuesday) we had to do some metaphors here are some of my metaphors I created in sentences from a list:
I had to do this task in Literacy, it was quite fun and I think I might try some of these in some of my stories. The list of metaphors weren’t at all that hard but there was some hard ones.
Telling the time of an Analogue Clock
On Monday, I had to do some more hero maths for school and we had to do analogue clocks again but instead of doing just telling the time normally, we had to do quarter to and quarter past, it’s very easy when you think about it because a quarter of 60 is 15 and half is 30 so half past 5 would be 5:30, quarter to 2 would be 1:45 and quarter past 2 would be 2:15.
Here is quarter to 12, Here is quarter past 1 and Here is quarter to 9
For Hero maths we had to learn how to read analogue clocks, we also had to convert a digital time and transfer that time to an analogue clock. Here’s the link to my work. I also used this app to find the time, I turned off the digital clock that’s on the app so it’s even harder to find the analogue clock time. You can also try challenge yourself to see how good you are at reading analogue clocks.
There’s a trick to reading analogue clocks and that trick is to count all the numbers as 5 for 1 – 12. The Long hand (The Longest arrow) of the clock is the minutes and the small hand (The smallest arrow) is the hour. So if this clock said this that means it would say 7:55 on a digital clock.
Today for maths we did work about credit, we worked in groups of 3-4 but me and my group worked in a 5, My group was: Angus, Elliot, Jed, Josaiah and Me. Here is the link for the work about credit score with our answers.
