Chromatoghrapy

Chromatography

Aim: To separate colours by using the process of chromatography.

Definition: A technique for separating the different parts of a mixture / solid using liquid.

Rainbow paper

Materials;

1. Filter Paper

2. Container

3. Felts

4. Liquid

5. Ruler

6. Pencil

Process:

Step 1: You have get one filter paper the thinner version of you normal filter paper so water can soak faster through it.

Step 2: Rule two lines on the paper with a pencil. You have to put it vertically and at the top draw a a line 2 cm apart from the top of the paper ans at the bottom draw a 1 cm line apart from the bottom of the paper.

Step 3: Get some felts and they have to be water based felts make sure you get three felts of any colour of your choice but ideal is black, red and green so you can get a surprising reaction.

Step 4: On the paper put 3 different colour dots with you water based felts on the bottom 1 cm line, it can be in any order of colour you want also for best result make the dots big but not to big.

Step 5: Fold the 2 cm paper line making a flap you can fold it any side you want since the colour can go through both sides.

Step 6: Grab a container or in other words a cup and hang your  paper making sure the longer side is facing the inside of the cup. - Make sure the paper is just above the bottom of the cup.

Step 7: Pour such a little amount of liquid or water into the container/cup making sure the top of the water is touching only the end of the Filter paper.

With My experiment and my buddy Sheila was a success I was so surprised of what happened, we learning or experimenting what colours were inside a colour that really got us confused at the start but after the result of the our experiment started to get what Mr palmer and Whaea Jo was talking about. We used the colours black, red and green they are just ordinary colour but when we added water and the filter paper started to soak up the liquid and get to the colour. The colours started to change the black turned into a rainbow the the red turned into pink and the green turned into a yellow and blue colour it was so cool. While was soaking higher more colours started to appear and the colours also spread up with the water although the bottom of black and green disappeared and was only at the top. I would really recommend trying this at home and try this experiment again.

Skittles

Aim: To separate colours by using the process of chromatography.

Materials;

1. Skittles

2. Petri Dish

3. Water/Liquid

Process:

Step 1:  Get a Petri Dish or a flat plate that is curved up on the sides.

Step 2: Place how many skittle in any order and any colours you want it in.

Step 3: After places all you skittles in you have to add warm water to just nearly over under the top of the skittles.

Step 4: Wait… it will take a few seconds or minutes for all the beautiful colours flow to the middle.

Step 5: Observe and record, it is optional but you can record while you observe it.

Step 6: Photo and Share, This is also optional but it will be nice if you can take photo of it and share it on social media or a blog.

Findings: Today for science we were learning about Chromatography, we did two experiments on it one about rainbow paper and one about Skittles. The skittles one was really fun actually really delicious after the experiment we could eat the skittles but at first when we started the experiment. It was blant we couldn't see any improvement but when time passed by we saw so much colour it was pretty the colours started to join and after a few minutes it mixed into a colour nobody actually likes. We actually had to container. So we compared the both of them and one was mixed and the other one was not one was mixed because we were kind of moving it a lot probably if we didn’t that wouldn’t have happened. But overall it was really fun.

Dirty Water Filtration Experiment

Dirty Water Filtration Experiment

Aim: To make a filtration plant using household materials.

Water Filtration Plant

What is filtration?

Filtration is separating solids from liquids by adding a medium through which only the liquid can pass.

Examples are:

1. Air Conditioners and a vacuum can also filter dust and pollen from the air
2. Coffee filters can separate the grounds
3. Liquid filtrations
4. Cake filter
5. Kidney filter

Materials

1. Plastic bottle
2. Scissors
3. sand
4. pebbles
5. Filter paper
6. Dirty water/liquid
7. Measuring cup (optional)

Process - ( use verbs or doing words in each step )

Step 1

Cut the bottle in half with a pair of scissors with you ending up with the top piece and the bottom piece separated.

Step 2

Put the top half of the bottle inside the other half of the bottle making the top piece as a funnel and the bottom as
the container holding the liquid.

STEP 3

Add a filter paper - (you need to fold it the correct way if you want it to work) fold the filter paper in half, then half it again
making four counters leave it in the position and open one of the slits. Then place it in the bottle with the pointy bit down
the neck.

STEP 4

Add half a cup of sand ( any kind of sand  ) into the filter paper while it is in the bottle.

STEP 5

Place half a cup more of pebbles on top of the sand and the filter paper making layers.

STEP 6

Pour dirty water or any other liquid you want to filter into the funnel in the speed you want depending on how you want it to
filter, my recommendation is that you go slowly.

STEP 7

Observe if the water is coming out clear or the liquid is separating chunks from the liquid. It will most probably still come out dirty but it is because it will need some time for your filter to filter out clear water.

Our experiment was ok we probably did not do the steps properly since the water was dripping a bit fast also the dripping color was nearly the same color as the dirty water we poured in the funnel. but we tried our best and we still did the experiment. We were not the only ones who got the same ending product, In my group was Lhysette, Shiela, Skyler and
including me. I enjoyed this experiment a lot and since this was our first proper experiment in our science module.
My prediction was that it would come out super clear and we could drink it but in reality my prediction was wrong but it was
because of scientific reasons.

My Art Module Process!

A week ago on Monday the 4th of February we started to do an Art Module about stop-motion we had three options to pick from that could be used for stop-motion. If you are wondering what stop-motion is, it is something involving motion and stop it's in the name you have to make a small and short movie using pictures you would have to take a photo for every movement so it would seem realistic. Now you must be wondering what's the point when you can just make an animation, But actually, it is way much easier than making an animation.

Our first option was whiteboard by me meaning whiteboard I mean we could draw our scenes, characters and more on the whiteboard it is much easier than the other two options. Since you can just rub it out, for example, your character was waving you can rub out the arm and make it higher or in a different position, in my opinion, I would rather decide to use whiteboard if you would try stop-motion use the whiteboard that is if you love drawing. 

Our second option is clay it is pretty hard but basically, you have to create characters and more out of clay the good thing is that it does not have to be perfect with sculpting it can be anything you want. 

Now finally the last option is Toy you can use toy figures like action figures cars lego people and much more, you can make it look like they are walking waving and other movements.

I have been doing one in a group with two other people Skyler and Megan, we have been doing a stop-motion using the whiteboard it is based on an angel and devil that became friends at birth and hang out all the time when the mother finds the baby angel gone she went and searches for her and she takes her away from the devil and at the end they reunite together. That is what we are for the end product so far we are only writing the script and drawing our storyboard we still need to create the stop-motion it's self.

Waitangi Day!

On Tuesday the 5th of February I started to read an Article to teach me more about Waitangi day. In primary school, I learned about it and was not very serious about it, I completely forgot about it.

 I don't know really know so much of Waitangi day but I guess Waitangi day is a very important day to New Zealand or Kiwi's themselves. But if there was no treaty my prediction is that probably we only made a treaty to not have a war but to hate each other by now. But thankfully to Hone Heke Pokai and William Hobson everyone is in peace. But before even the British came to NZ an English man named James Cook found our country New Zealand and just put it on the world map when he sailed back to his home he told every on to go check NZ out.

Every year on the 6th day of February it is Waitangi day it's not just an ordinary day of February it is one NZ's Holidays. Some people celebrate it and other people just take it as a day of work or school, some people got to churches and they sing and dance. I have learned so much stuff after reading articles of Waitangi day thanks to Miss Allan our wonderful teacher who cared about Waitangi day allowed us to learn more about a wonderful day in NZ.

How it all started is when a significant day was celebrated in New Zealand's history.

Why do people celebrate Waitangi day is because we want to celebrate how the day everyone come together.

What are things you can do on Waitangi day is that you can go to churches or actually have a road trip to Waitangi there are so many things you can do that can actually be so much fun.

Waitangi day is all celebrated on the 6th of February but the first day of Waitangi day was in the 1840s.

If you are wondering where Waitangi day would be holding it would most probably be held in Churches, Whares and much more.
