Write a paragraph about your findings.

The sugar at first was not as Crystal like as it was when we put the vinegar in it. But when we put water in the sugar it went runny. With the iodine in it it went runny and the crystals got bigger but also colored brown.The salt didn't really have reaction to the vinegar and water but it did with the iodine some of it went black and the rest turned yellow. The corn flour with water and vinegar went like oobleck and hard.But with iodine it went runny and didn't really dissolve. With the baking powder it just fizzed with all of them.

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.
