Hurumanu 3 essay

Hey guys so in our Hurumanu 3 we have been making persuasive writing. We had an option to choose from and I chose Why cats are better than Dogs.

Here is my writing hope you like it!! :)

Why Cats are better than Dogs

Do you want to lose half of your money? Certainly not,we all love Cats and Dogs but I’m here to tell you why Cats are better than Dogs. Dogs rely on you to provide them  regular grooming. Cats don’t take up much room in your house. Dogs bark really loud and disturb your neighbours.

Dogs rely on you to provide them regular grooming. Dogs need you to groom them and they rely on you to groom them. It takes about 2 to 3 hours to be groomed. For Cats, they keep themselves clean and you don’t need to always groom them for the same amount of time as Dogs. You also have to pay money to go to a personal groomer for your Dog. On the other hand you also have to buy a Dog house. The cost of a cat house is about $80 but the cost of a dog house starts at $300. 

Average Dogs are about 11 to 24 kilograms and they can take up plenty of space in your house,especially when you have a house that barely has room. Dogs are pets that love to walk around your house and you need to be able to provide enough space for them to walk around. While cats don’t take up much room in your house and they hardly ever knock anything over like dogs do. Most of the time Cats are out of the house. They are much more tidier.

Dogs bark really loud and can disturb the neighbours at night. A Dog's bark can be heard from a distance of 1.8km. Dogs can be really loud, if a neighbour is walking past Dogs can scare them away. Dogs bark can scare young kids,you might even get a complaint. Cats meow are really low and silent. They don’t make loud noises like Dogs.

If  you don’t want to get complaints from your neighbours you should get a Cat. If you want your house to be clean and have more space you should get a Cat. You don’t have to take your Cat out for grooming all the time as Dogs. Now I know you will agree with me that Cats are better than Dogs.

Finding Dory (Hurumanu 2 music)

 Hey guys today I'm gonna be showing you what we did in our Hurumanu 2. In our Hurumanu 2 we have been making our own music and mixing any kind of sounds together. We had a scene from Finding Dory and we had to make sound that was different from the original. Mr Tisch shared the Finding Dory. After that we had to put the sound with the Finding Dory scene.

I want to find out what happens to Gummy Bears when they are put into different solutions.

Prediction: I predict that they will dissolve into the solutions. 

Method: get your equipment and put on your safety glasses, using the marker pen.write the name of the condition on the petri dish.DRY, WATER, SALTWATER, SUGAR WATER.weigh gummy bear and write the weigh on the the petri dish measure 40ml of the solution and pour it into the petri dish. 

equipment:

1. 4x gummy bears

2. 2x petri dishes

3. paper towels

4. marker pen

5. water

6. sugar water

7. salt water

8. electronic balance

9. beaker

10. measuring cylinder 

step 1. get your equipment.

step 2. put on your safety glasses

step 3. using the marker pen.write the name of the condition on the petri dish.DRY, WATER, SALTWATER, SUGAR WATER

step 4. weigh gummy bear and write the weigh on the the petri dish.

step 5. measure 40ml of the solution and pour it into the petri dish. 

	Dry	Water	saltwater	Sugar water
Initial weight of gummy bear	5.81g	5.36g	5.73g	5.45g
Final weight	5.70g	6.52g	6.22g	6.05g
Weight difference	Lost 0.11g	Gain 1.6g	Gain 1.16g	Gain 0.60g
Initial volume		40ml	40ml	40ml
Final volume		0ml	10ml	7ml

Volume Difference

Lost 40ml

Lost 30ml

Lost 33ml

Discussion

1.The normal water was transferred into the gummy bear the most.

2.The dry gummy bear lost 0.11 grams over a week.

3.The sugar water diffused faster than the salt water

Diffusion is the movement of a substance from an area of high concentration to an area of low concentration.Diffusion happens in liquid and gases because their particles move randomly from place to place.Diffusion is an important process for living things.

HEROES

Hello guys in our Nga tangata Hurumanu 1 we studied the lives of some local, national and international heroes. A hero is a male or a female or group of people who aren’t measured by the size of their strength, but the strength of their heart. I also made slides of 6 sport heroes and they were, Sir Richard Hadlee, Chelsea Bremner, Jo Aleh, Sir Peter Blake, Lebron James and Serena Williams. After that I made some slides about a local hero who achieved in his community. Bill Sutton was a portrait and landscape artist, who also taught some of the famous Canterbury artists in Christchurch. Then we also read about a musical group called Crowded House. They were said to be heroes for one day when they performed in Christchurch recently. We talked about the meaning of hero worship.The hero I worship is Jeon Jungkook. The earthquake heroes I searched about were George Piper, st.john Ambulance, Amo pertini, Andrea robinson, Andrea cummings, Ashley M Vicker, Blair Corkran and Charlie hobbs.I also wrote about myself as a superhero,my alias was Ichika. Here is my stroy. Hi guys my name is Ichika and I’m 17 years old. I’m also a superhero. I live in Japan. Everyday is exciting for me,I’m in the hashira (demon killing corp) I always go to the forest and hunt down demons, even though I’m short but that doesn't matter to me as long as I have my sword with me. After I have done that I go into my favorite Ramen restaurant that I always go to,after I have eaten my ramen I love to get myself some dumplings that you get for free.

Hope you like it :)
