Skittle Experiment

Chromatography - Skitlles:

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

Materials:

1. Skitlles
2. Petrie Dish
3. Liquid/Water

Process:

Step 1: Get your Petrie dish.
Step 2: Get your skittles.
Step 3: Place the skittles around the Petrie dish. (Make them even)
Step 4: Pour a decent amount of liquid/water, enough to submerge half of the skittle.
Step 5: Watch the skittle turn white as the colours of it melt through the water.
Step 6: Eat the skittles if you want to, and enjoy your rainbow water.

Findings & Reflection:

I found the skittle's colours disappear as it slowly expands and mixes together. When the colour started to spread around the Petrie dish, the other half of the skittles was turning white. We also ate the skittles at the end.

Chromatography Experiment

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. 

Materials:

1. Filtered Paper

2. Ruler

3. Green Felt Pen

4. Black Felt Pen

5. Red Felt Pen

6. Container/Cup

7. Pencil

8. Liquid

Process:

Step 1: Get your filtered paper and rule up a 2 cm pencil line on the top.

Step 2: Rule a 1 cm pencil line on the bottom.

Step 3: Get your black, red, and green felts, make a dot for black on the 1cm line same with red and green.

Step 4: Fold your filtered paper on the 2cm line. 

Step 5: Get your container/cup, and place the folded part of the filtered paper on the top of the cup.

Step 6: Pour a little amount of liquid/water for the filtered paper to absorb.

Step 7: Watch the colours rise up to the paper and you should see what colours are inside of the specific colours.

Findings & Reflection: 

I found out that black and green had a blue colour at the end but the colour red pretty much stayed the same colour. So I think that red had the least colours inside which was red and a bit of pink. Green had the second lest colours and they were blue, yellow and a little bit of green in the middle. Black had the most, it had pink, orange, red, blue, and a little bit of black which is also in the middle. 

 I did the same thing, but with different colours. I chose the colours orange, pink, and yellow. When it started rising there weren't many different colours appearing. They were still orange pink and yellow. Also when I was doing this experiment I thought of something. Maybe darker colours give more colours than lighter colours. That's why when I did orange, pink, and yellow not much colours came appeared. 

Dirty Water Experiment

Aim: To make a filtration plant using household materials.

What is filtration?

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

Examples are:

1.  Tea bag
2.  Water filter
3.  Coffee filter
4. Aquarium filter

Materials

1. Rocks

2. Pop bottom top

3. Coarse sand

4. Fine Sand

5. Coffee filterer

6. Elastic sand

7. Pop bottle bottom

8. Dirty Water

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

Step 1

Cut the bottle in half.

Step 2

Put the top half upside down.

STEP 3

Add layers of rocks, coarse sand and fine sand.

STEP 4

Get 1 cup of dirty water.

STEP 5

Pour dirty water into the bottle and it should start to filter.

STEP 6

Observe how the water flows. 

Measurements

Write a short sentence about the water every 1 minute. 

Include 'How much water has filtered through', 'How fast it is dripping through', and 'How clear the water is'.

There was a decent amount of water that filtered through, it dripped pretty fast.  But it wasn't clear as I thought, although it was a really successful and a fun experiment to do. 

Warning

Make sure that an adult cuts the bottle in half. This water filter is just an experiment and should not be used for drinking water.

Avoid using charcoal briquets, as these can contain chemicals you don't want in your water. Use the activated carbon for water purifiers instead.

"Brotherhood" Stop Motion Film

This term, on art we have been learning about "Stop Motion". Stop motion is an animated film making technique where objects are moved between individually photographed frames.

Then we had to make our own stop motion film, the goal was to make a stop motion film that was 20 seconds long, or longer. To make our stop motion film we had to pick how we were going to make our film. We either had to make it on a whiteboard, where we have to keep drawing and taking pictures every time we were moving a character. Or we could do it on clay and make figurines and take pictures of it, every time we move it. The last choice was lego, I've seen lots of videos about it and it's pretty cool. After that, we had to be in a group of 3 or less. I grouped up with Axle and we worked really good. We were placed in a group, A or B Axle and I was in group A.

Before we start making our film we needed a plan first. So we made a storyboard so we know how our story is going to work. Here is the picture of our storyboard. We are also doing a script but we are still working on it. Here's a preview.

Treaty of Waitangi History Presentation

On February 6 we celebrated Waitangi day, but my class didn't know what was Waitangi day was . So our teacher Mrs Allan gave us readings about the Treaty of Waitangi, and who was the first person to sign the Treaty. Although maybe some of you also don't have a clue of what Waitangi day is. So I made a slideshow explaining what Waitangi day is, we researched a bit to find out some information. I now understand what Waitangi day is for and I hope you will too in this slide show.
