What is another experiment you could do using chromatography and how would you do it.
Title: police chromatography
Aim: To find out how to make fingerprint powder and how it works.
Materials: corn starch,Measuring cup, matches or lighter,A candle, A ceramic bowl, a knife or paint brush,, A mixing bowl.
Process: Step 1: Follow the link to see how to make fingerprint powder.
Step 2: Click this link. Click Me!
I am a student at in Uru Mānuka. In 2020 I was a year 8 and in 2021 I will be a year 9. This is a place where I will be able to share my learning with you. Please note....some work won't be edited - just my first drafts, so there may be some surface errors. I would love your feedback, comments, thoughts and ideas.

skittles experiment
Skittles
Aim: To separate colours by using the process of chromatography.
1. Petrie dish
2. skittles
3. water
Process:
Step 1: put the skittles in the petrie dish
Step 2:then add water
Findings: What happened was when we put the water into the petire dish and the colours came off the skittles.
Reflection: i have learnt that if you put water with skittles the colours
What did the colors do? The colors came off and made like slices of pie with each colours
Did the colors mix together? The colors did not mix together they stayed in the pie slice
Why not? what i think is that the colors did not mix because they had different chemicals in them and would not mix.

Chromatography
Aim: To separate colors by using the process of chromatography.
Materials;
1. cup
2. filter paper
3. water
4.water base pens
Process:
Step 1: color three dots
Step 2: pour water in a cup
Step 3: put the filter paper in the cup
Findings: the colors spread out and mixed
Reflection: i learnt that colors have different colors in them
Reflection: i learnt that colors have different colors in them
When we have a reliever:
Today with our reliever I started off fine and then I wanted to sit with my friends. And listened to music. When we have guests in our class I should act the same when the teacher is teaching. And treat them with respect. Next time I will behave and stay at my seat. And not listen to music.

My past in drama
In my past week we have been learning about healthy food. On Tuesday we watched a video of what takeaways look like in their photo compared to real life. Today we said a phrase of healthy food I did eat well stay swell. And when I said my phrase I had to think about my position on stage and how I said it.

do you know how to make your own filter
What is filtration?
Filtration is separating solids from liquids by adding a medium through which only the liquid can pass.
Examples are:
- a tea bag is a filter
- coffee uses a filter
- a pool has a filter
- your kidneys
Materials
1. dirty water
2. bottle split
3. sand
4. pebbles
5. filter paper
6. scissors
7. cup
8. funnel
Process - ( use verbs or doing words in each step )
Step 1
Cut the bottle in half.
Step 2
Put the top half upside down inside the bottle bottom.
STEP 3
Add layers of filter paper and add sand and pebbles.
STEP 4
Get 1 cup of dirty water.
STEP 5
Pour dirty water into the upside down bottle.
When I did my one we did it all correct but it dd not work it was still dirty. I think it did not work because we only put one layer of filter paper.
how to put water in the freezer and make it not freeze
for week 2 of school we had to find out how much salt to put into water to make it not freeze.
- What do we need to find out? THE AMOUNT OF SALT THAT MUST BE IN WATER BEFORE
- IT WILL NOT FREEZE WHEN LEFT OVERNIGHT IN THE FREEZER.
- How will we find it out? What i think is that we put different samples in the freezer and find
- out the next day
- How will we record what we find? Well we can put a table in our drive and have sample 1 in
- one box and so on.
- What equipment do we need for the experiment? Cups,salt,freezer and water.
- How long will it take? One night.
Step 1: put half a cup of water in a cup.
Step 2: put different amounts in the cups.
Step 3: name them for example test 1 and so on.
Step 4: wait overnight and have a look to see which one is good is still water the one that is water
is the right amount.
is the right amount.
chemical reaction
what you need to get for the experiment is baking soda, vinegar, X2 cups,tray.what we want to do is to make a chemical reaction (fizz).First clear a table and put a tray on it.Second put 2 cups in the tray.Then put a table spoon of Baking soda in one cup then add vinegar into the same cup stand back and watch as it should fizz up.And in the other cup pour the vinegar in then put the baking soda in.
