Gummy bear

 Disscusion

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 liquids and gases because their patricals move randomly from place to place. Diffusion is an important process for living things, it is how substances move in and out of cells.

Body Percussion

 Talofa,  welcome back to my blog today we are going to be learning about body percussion. 

What does body percussion mean? Body percussion means using your body.

We had some different stuff we could use for our sasa. The stuff we used drum sticks, jandals and a brown tube. In my group we had to record our body percussion, in my group we had Finau,Neelah, Me, Artee and Eunize.

Hurumanu 1

 Talofa, 

This week we ave been doing slideshows about hers and other topics of heros. 

I wake up at 6:30 and I go for a morning run, just around the block a few times. By the time i get home it’s just after 7:00. I make me a light breakfast which is 2 Eggs and 2 bacon. After I eat I go for a shower and sing in the shower. I do have errands but that's not until 11:00 when I met my crew, which is Lord of Nora, Lord of Kora and Lord of Dora. While I wait I'm going to watch Movies and kinda relax before I go to the lab. 

After I had a nap, I got myself ready and started my car to go to the lab. Under my clothes I was wearing my suit, just in case there was an emergency while I was driving to work. I was the first one out of my siblings  to get there so I set everything up and waited for the rest to come. While I was setting everything up Lord of Zora and Nora came at the same time. Lord of dora would always come late to our meeting. Our meeting was not that important but we just came because we had some stuff to do. 

While we were working on our stuff lord of dora came just in time because the alarm went off, because we had an emergency to go to. When we came back from our emergenc it was time for us to go home and relax. I got home and had a shower and ate  my dinner and watched a few movies until I went to sleep. I jumped in bed and read my book for a few minutes and went to sleep, because I was so exhausted from today.

Materials:

1. 5 skittles 

2.Water

3.Petri dish

4.beacker 

process:

Step 1.Plce the skittles into the petri dish around the edges

 Definition: Chromotography is a method of seperating out matriels froma mixture

Aim: To seperate colours by using the process of Chromotography. 

Materials:

1.Felt

2.water

3. Chromotography Paper

4.Testube 

Steps: 

1.Cut up chromotography paper 

2.fill up your test tube with water at 1cm

3. Add at the bottom a dot of your colour and put in on the  Chromotography paper 

4.Then we put the paper with the dot at the bottom, we put it in the test tub of water and wait for a few minutes. 

5.watch the colours turn into heaps of colours and . 

Questions
