Serial Dilution

In class on monday Paige and I done a science experiment, We were learning about Dilution and what it does our science experiment was repeated.

Aim: To make a dilution series to investigate concentration.

Equipment:

A potassium permanganate crystal (KMnO4)

six large test tubes

a plastic transfer pipette

a test tube rack 10ml measuring cylinder

Water

Spatula

Method:

1. Put the 6 test tubes in the rack and label the rack with numbers

2. Using the measuring cylinder, fill the test tube 1 with 10ml of water then fill the empty ones with 5ml of water

3. using your spatula pick up a little bit of KMnO4 in test tube 1

4. carefully mix the water and the KMnO4 together until it has disolved

5. using the pipette carefully take exactly 5ml from test tube 1 and put in test tube 2

6. rinse the pipette throughly to ensure that no purple sollution remains

7. carefully mix test tube 2 and repeat the transfer process, transfering exactly 5ml from the soultion from test tube 2 to test tube 3

8. rinse the pipette again and repeat the transfer process for test tubes 4, 5, and 6

Conclusion/Descussion:

I saw that the colour changed when I kept adding 5ml to test tube 2 3 4 5 and 6 it went from purple to really light pink, The first one was the least dilute because it had the most KMnO4 and the last one was the least dilute because it had the least KMnO4 in it. I think this experiment is really cool and fun I recommend it for ages 10+.

Zombie Apocalypse

Today in social studies I learned about Zombies and what to do in an apocalypse i wrote down 10 things you have in one here is my google drawing about it

In Textiles we are making cards for loved ones and everyone else and I decided to make one for my best friend because she is important in my life and I wanted to make her something special.

These are my cards they are pretty bad and she might not want it but I don't care I like them.

These are my cards I hope you like them please leave a THP ( Thoughtful, Helpful and Positive comment) and add a question in there. BYE. 

Inside and Out Hurumanu 2

What am I learning?

How does this show my learning?

That I understand how to make things like this for my learning

What am I wondering?

Carbon Footprint

Carbon Footprint

Hi today for Textiles I made a poster about Carbon Footprint and how its affecting our earth, I made it so you have when it was founded and what its about and 5 facts to reduce your carbon footprint.

I also put a lot of pictures of the carbon footprint and they are quite small so I will put my poster down the bottom

Thanks for reading my blog post please leave a Thoughtful Helpful and Positive comment and chuck a question in there for me to reply to you BYE

Science Tests

Testing for protein

Aim: To test if a sample of food contains protein

Hypo: Only the milk will turn purple

Equipment: Test tube, Sodium hydroxide (haOH), Copper sulfate (coSO), Food sample.

Method;
Step 1- Place about 2 ml of the sample into a test tube and add 5 drops of sodium hydroxide.
Step 2- Add 5 drops of copper sulfate.
Step 3- Shake the test tube gently side to side.

Results:
Apple: Negative
Potato:Negative
Bread: Negative
Milk:Positive
Egg:Positive
Sugar:Negative

Conclusion:
The egg and the milk has protein in it but the

Hurumanu 8 (Health)

What is Whare tapa wha?

It is the Maori word for the  4 dimensions of Hauora ( Well being)

How I illustrates to Hauora (Wellbeing)?

It is the 4 dimensions of well being 

How did I participate during this lesson?




What is your current state of your hauora?

My hauora is really good because I am running around and playing sports I don't think I need to work on anything because it is really good.
