Findings

Describe your crystals in the table below.

Crystal Type	Shape (Describe the shape)	Size (of individual crystals)	Hardness (Crumbly to Rock Hard)
Borax	Cubical		Hard
Sugar	Cubical		Crumbly
Salt	Cubical		Medium

What crystals worked out best and why?

The saturated sugar mixture has worked out poorly, there was not any trace of crystallization in the cup or around the pipe cleaner that we've used. The most probable reason that we can think of why it hasn't worked is that our mixture has not been saturated enough. We concluded that because our mixture was still very much liquid and not almost as thick as syrup.

However, the salt and borax mixture worked out like magic. They were the best results that we've had in this experiment. Though there were more crystals in the borax mixture; the container in which we had the salt mixture had more crystals in and around the inside of it. it was quite thin but at the least, it was very much visible when looked upon closely.

The experiment was a success except for the sugar mixture that we did, which we figured was not as saturated as the salt and borax mixture.

Tane Mahuta Entry One

I am part of the tane mahuta group

our goal is to bring the school back to its former glory

today we explored places including the orchard

my favorite area in the school is the field because of its personality and potential

my best idea is to build a new playground since we only have one and its used from year 7 to year 9 (usually)

Homemade Filter (Science)

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.  Water Filter
2. Coffee Plunger 
3.  Jug 
4.  Tea Bag

Materials

1. Plastic Bottle

2. Sand

3. Filter Paper

4. Stones / Pepples

5. Scissors

6. 

7.

8.

Step 1

Cut the bottle into half using scissors 

Step 2

Put the top half upside down on the top of the bottom half

STEP 3

Add layers of Sand, Stones and filter paper in this order, Filter paper, sand, stones

STEP 4

Get 1 cup of dirty water and tip it on the stones, sand and filter paper

STEP 5

Watch the water change to a clearer color!

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'.

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.
