Indicators

Indicators

Last week in Science we did a project using Indicator's. 

What is an acid?

There are many acids that there are to use, the acid we used for the project Hydrochloride acid and Hydroxide acid.

----------------------

What is an alkali?

An alkali is a base that is soapy like many cleaning products.

-----------------------

What is an indicator?

An indicator is a small tube that changes colour when you put it in an acid.

-----------------------

We poured our substance into the Indicators and mixed it with all the other mixtures we had. The colours in the Indicators changed colours from it mixing into the substance.

Thanks for reading!

Sports Heroes

 For the past few day in Hurumanu 3 we have been working on a slide about sports heroes. It is about people that play famous sports and are heroes of achieving it and some making it to the Olympics. We had to write 2 slides for a type of hero that plays a sport. But for local hero I only did one which was my brother.

Here is my slide!

Invention Story

For the past few days we have been learning about wheels and inventions. Then we all made an invention story adding a person making an invention. We first did a draft in our book and then copied it onto a google doc. My story is about 3 pages long. This is my story that I did.

One Morning a 16 year old boy named Simon Cycle woke up in the morning for a school day. He got breakfast and combed his hair, just it was a normal school day.

Simon turned on the tv and it was on the News channel. News reporter David, he had his own show for training wild animals. It was quite big on tv.

Suddenly on the screen David started to say the daily news. “Welcome to channel 4 news. This morning we have breaking news, a blackout sale has started at about 7:30 AM. There have been 2 car crashes early this morning because of all the clutter of people trying to get into the mall.

Then Simon turned off the tv and thought of an idea. He planned a vehicle that could get him to school faster than ever. The invention he was planning on doing was a ‘Gliding Bus!’ The bus had shiny yellow paint and crystal clear windows on each side of it.

The best part about the bus was the engine that made everything come to life!

A few minutes later Simon started up the bus and the garage opened. He drove up to the street and pulled a lever that made the bus fly.

So the flying bus flew over the traffic. He thought “Wow that could’ve been me in one of those cars stuck in that big traffic jam. It took about 5 minutes to get to his school but if he would be in a car it would’ve been 20-25 minutes!

As he got to his school Simon landed, and parked it.

Simon walked inside the school and noticed that there weren’t many people at school there because of how early it was. He probably thought that the reason why nobody was there was because of all the traffic on the road.

Next Simon did everything he wanted. He grabbed all the food from the cafeteria and ate all the food. 

 

Jelly Baby Osmosis

 Jelly Baby Osmosis

What we did was we first got 8 jelly babies in 2 colours ( pink and yellow ) each of us got 2 per each person. We then got our petri dish and filled it up with either sugar/salt and water.

We took our jelly babies and placed to in each dish. There were 3 petri dishes in total for (Maddison, Ayla, and Me). Maddison used Water, Ayla used Salt, and I used Sugar.

Hypothesis : What will happen to the jelly babies in each solution?

Ayla : I think they will all expand but the water one will have the least growth

and the salt will have the most.

Erin : I think the jelly babies all with grow but the water one won't grow as much as the salt and sugar one,I also think the salt one will grow the biggest.

Maddison : I think they will grow but salt will be the smallest and sugar would be the

biggest and they would dissolve in the bath if salt,sugar,water ,i feel like the the jelly babies that

go in salt water will dissolve 

---

The results were :

The salt one was falling apart when we moved it.

The sugar one felt the hardest and most put together but still a bit moshed.

The water one fell apart but not as much as the salt one.

Maori Battalion Heroes

 In period 3, 4, Hurmanu 1 we are learning about Maori Battalion's. We had to read about the Maori Battalion's and then write the answers about the paragraph's we read. 

This is my google doc about the Maori Battalions

Skittles Observation

Yesterday in period 2 Science we did a experiment using Skittles. The things we used were Warm water, Petri Dish, and Skittles. We all worked in buddies, I worked with Maddison. One of us brang the Petri Dish up to the table to fill it up with some warm water. Then got 5 individual colours of Skittles to put in the water. It was fun to see the Skittles dissolve into the water and spread.

These are some pictures of what the Skittle Experiment looked like.

Bunsen Burner / Boiling Water

Yesterday in period 2 ( Even though I wasn't really at school that day). But we got out the gear and we put it together, then we got the beaker and filled it with cold water, and then we lit the Bunsen Burner. Then let it sit and boil for 5 minutes. We also put a thermometer and took its temperature. Then we had to rinse the beaker and let it sit otherwise it burn our hand.
