Chromatography

Skittles

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

Materials;

1. Petrie dish
2. Liquid
3. 5 Skittles 

Process:

Step 1: Get a Petrie dish or a plate
Step 2: Put your 5 skittles in the Petrie dish
Step 3: Put a little amount of water, just a little bit.
Step 4: Watch the water turn to a rainbow colour.
Step 5: Time to eat your skittle
Findings: 

So what happens is when you put a skittle or mm in the water, their colour is going to wash away because they're just a food colouring

Reflection: What have I learned from this experiment?

I learned that when you put mm or skittle in the water there colour will start to disappear
What did the colours do? It disappeared 


Did the colours mix together? Not at the start but when it was like 1 minute, it started to mixed.

Chrotomagraphy

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

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

Rainbow paper

Materials;

1. Black felt pen
2. Red felt pen
3. Green felt pen
4. Liquid
5. Container
6. Filter paper

Process:

Step 1:  Rule a 2 cm line at the top of the Filter paper 

Step 2:  Draw a 1 cm line at the bottom of the Filter paper 

Step 3: Put a tiny amount of water in the Container

Step 4: Put 3 dots in a different colour in the 1 cm line

Step 5: Fold the top of the filter paper where there is 2 cm dot
Step 6: Hang the filter paper in the container

Step 7: Watch the colour go up the filter paper 

Reflection:

What happens is that the three colour dot that was in the Filter paper goes up because when the liquid touch the filter paper it will then touch the three dot colour. So when the water goes up it will go with the colour too.

I really like this science experiment because I learned that when the water touches the colour it will go up with the water. I'm really excited for our next experiment.

What is Filtration?

Aim: To make a filtration plant using household material.

What is the filtration?

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

Materials

1.Pop bottle top 

2.Rocks

3.Coarse sand

4.Fine Sand

5.CoffeFilterer

6.Elastic Sand

7.Pop Bottle bottom

8.Dirty Water

Examples are:

1.  Tea Bag
2.  Water Filter
3.  Aquarium filter
4. swimming pool 

Process - 

Step 1

Cut the Plastic bottle in half

Step 2

Put the top half upside down 

Step 3

Add layers of Stone, Coarse sand and fine sand in the top of the plastic bottle.

Step 4

Get 1 cup of water 

Step 5 

Pour the dirty water 

Step 6

Observe how the water flows now the water has to be not flowing and
if it’s clear, then you’re all good to go and you did a great job but if it’s still dirty, maybe you should fix it and try again

Measurement

The water filled the quarter of the plastic bottle, But before that happen the water came so fast. It’s not very clear though however there wasn’t any dirt to it. 

Our experiment turned out pretty good I hope that we will do an experiment again in science.

What is stop motion?

On art, we are doing a stop motion about someone we like and a Roald dhal character. My group is Joseph, tukz and me. The stop motion that my group is making is very cool because it has a Roald dhal character and the Roald dhal character is very funny. But we are still working on our stop motion. My group is still working on the script but we are nearly done to finish.I'm excited to make our stop motion next week and we will try to make it come alive like a cartoon tv show.

What is stop motion? Stop motion is a small animation that people create with something like clay or toys. When you are making a stop motion you need to have a Light and a Camera. That light helps the camera to make the video brighter and more color full. If you are making a stop motion you are allowed to move the camera so you can followed your character, but you have to keep it still so that when you put it together it will look cool.

This Friday my class did a blog post about Waitangi day. It was very fun because I have learned something about Waitangi day. If you want to learn about some things about Waitangi Make sure to check out my Slide show.
