Rainbow Paper

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. Felt Pens

2. Ruler

3. Pencil

4. Liquid

5. Container

6. Tissue Paper

Process:

Step 1:Rule the tissue paper. 2 cm from the top and 1 cm from the bottom

Step 2:Pencil line the marks.

Step 3:Add dots out of the 3 felt colors on the pencil line of 1 cm  

Step 4:Then fold the Tissue paper on the 2 cm line. 

Step 5:Then place the tissue on the side of the container

Step 6:Pour a little bit of liquid in.

Findings: Write about what happened.

Reflection: What have I learnt from this experiment? That black has blue yellow and red inside of it.

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.  kidney                                   
2.  Jug 
3. Tea bag 
4. Swimming pool

Materials

1. Stones/Pebbles 

2. Container 

3. Sand

4. Dirty water

5. Funnel

6. Scissors

7. Filter paper

8. Cup 

Steps 

Step 1

Cut a bottle in half if you do not have a funnel.

Step 2

Put the top half of the bottle upside down on the top of the other half of the bottle.If you have a funnel you could place it on something like a beaker or a shape that´s like a cylinder.

STEP 3

Make a cone with some filter paper by folding it.Place it on the funnel.Add half a cup of sand first and pack it in.Then add half of cup of pebbles on top of the sand.

STEP 4

Get 1 cup of dirty water and pour it into your funnel and watch the reaction.

Reaction 

Its starting to drip but the water got more clear when it came out the funnel.Because it got filtered by all the stuff in it.We didn't get any clumps.
