Dilution and Filtration

Last week for hurumanu 4 which is science. We were diluting copper nitrate and sodium hydroxide.

Equipment- Test tube rack, 4 test tubes, pipette, the chemical solutions Copper Nitrate and Sodium Hydroxide

Method- Take 4 test tubes, in the first test-tube measure and pour in 10ml of Copper Nitrate. Then take 1ml from the first test tube and pipette into the second test tube. Add 9ml of water to make it up to 10ml. Then repeat for the third and fourth test tubes. 

Making the precipitate- Now add 5ml of Sodium Hydroxide to each test tube and take a picture in front of white paper.

Then we had some questions to answer.

1. Which test tube had the most concentrated sample of Copper nitrate? The first test tube was the most concentrated out of all of them.

2. When we added water what were we doing to the concentration of the solution? When you add water you are diluting the copper nitrate.

3. Which concentration of copper nitrate formed the most precipitate, why do you think this is the case? The first one was the most concentrated because it wasn't mixed with any water and it was also the most blue.

4. Make sure you have a photo to post!

Some photos of what we did last week

  

Reading Tangata Whenua

For the last two week, I have been working on a book about New Zealand and the history behind it. The book I got is about Tangata Whenua, The name of the book is Tupaia. Tupaia is about the native people that lived here first before captain cook came to New Zealand.

For one of my activities, I had to describe in my own words what the word mana means.

Here is the work I did for this period.

Sugar And Drinks

This week on Tuesday we had math and health. For maths, we look at sugar and drinks and how much sugar was in drinks. For the activity we had to work in groups, we had to put teaspoons of sugar in a small Ziploc bag. The amount of sugar we put in a Ziploc bag was the amount of sugar in a drink.  I was really surprised when a bottle fizzy had 20 teaspoons and sports drink Had 14 teaspoons in it. We have some photos of our math activities.

This is a photo of my group.

This is a photo of all the sugar in the ziplock bag for each drink 

I hope you enjoyed my blog post I really found a lot about sugar and drinks. And all the measurements of sugar are interesting and some are really surprising with how much sugar they had in them.

Pink River Dolphins

Today while I work from home I did this activity where I had to choose an animal to research about and make a D.L.O then post about it on my blog. I choose the animal pink river dolphin to research about. I made a slide show about the pink river dolphin and all the thing I research about I hope you like it. I also have a video at the end of the slide show about the pink dolphins.
