Aim: To learn about a saturated solution and how to make crystals

Crystal video

Definition of solution: 

A liquid mixture, when something is dissolved into a liquid (eg: sugar in water) 

Definition of saturated: 

Having or holding as much as can be absorbed of something (when no more sugar or borax can be dissolved into the water)

In groups of three, you will make three different types of crystals and compare the results.

Borax Crystals

Borax Crystals time-lapse video

Ratio; 3 Tablespoons Borax per 1/2 cup water

Materials

1) Tablespoon

2) Borax

3) Water

4) Cup 

5) Peg

6) Pipe Cleaner

Process

Step 1: Put 3 Tablespoons of borax into some water

Step 2: Mix for around 10 minutes or until the water can't take any more

Step 3: Combined the pipe cleaners into a star shape

Step 4: Put it in the cup with the borax and water using a peg

Step 6: Wait a few days and watch the crystals grow

Sugar Crystals

Sugar crystals video

Ratio: 1 cup sugar to 1/2 cup water

Materials

1) Sugar

2) Water

3) Cup

4) Stick

5) String

Process

Step 1: Put 3 Tablespoons of sugar into some water

Step 2: Mix for around 10 minutes or until the water can't take any more

Step 3: Put the string around the stick

Step 4: Put it in the cup with the sugar and water using a peg

Step 6: Wait a few days and watch the crystals grow

Salt Crystals

Ratio: 4 Tablespoons salt to 1/2 cup water

Materials

1) Cup

2) Salt

3) Stick

4) Water

5) String

Process

Step 1: Put 3 Tablespoons of salt into some water

Step 2: Mix for around 10 minutes or until the water can't take any more

Step 3: Put the string around the stick

Step 4: Put it in the cup with the salt and water using a peg

Step 6: Wait a few days and watch the crystals grow

Findings

Describe your crystals in the table below.

Crystal Type	Shape (Describe the shape)	Size (of individual crystals)	Hardness (Crumbly to Rock Hard)
Borax	Crystal,	They come out Big	they are Hard
Sugar	Cubed	small	soft
Salt	Cubed	medium	hard

After watching the videos as a class, explain how the following crystals are formed:

Type	Explanation
Salt	While the ocean is a natural salt brine, hydraulic mining (or solution mining) of salt involves pumping water below the earth's surface to dissolve salt deposits and create a salt brine. This brine is then pumped to the surface and evaporated to create salt. ... Most table salt is produced with this method.
Sugar	Refined sugar is made from raw sugar that has undergone a refining process to remove the molasses. Raw sugar is sucrose which is extracted from sugarcane or sugar beet. The sugar syrup is concentrated by boiling and then cooled and seeded with sugar crystals, causing the sugar to crystallize out.
Snowflakes	A snowflake begins to form when an extremely cold water droplet freezes onto a pollen or dust particle in the sky. This creates an ice crystal. As the ice crystal falls to the ground, water vapor freezes onto the primary crystal, building new crystals – the six arms of the snowflake.

CRYSTAL TYPES

AIM: TO LOOK AT THE 7 DIFFERENT TYPES OF CRYSTALS

7 different crystal shapes

Aim: To see which chemical
mix creates the most gas.

Hypothesis: (What do I think will happen)
I thought that the gas would make the balloon grow really big and that the liquid would rise a lot.
Materials:

1. 3 bottles 
2.  tsp baking soda
3.  vinegar 
4.  soda water
5. cup 
6.  balloons
7. funnel 
8. yeast
9. sugar
10. salt

Steps:

1.  grab the bottle make sure it's empty and dry
2.  grab your funnel and balloon
3.  Get the first ingredients 
4.  Pour 2 tsp of the yeast and 1 tsp of sugar, make sure to pour it in one at a time.
5.  Then wait for it to rise.
6.  for the next experiment do the same thing with the salt and baking soda for the other 2 ingredients 

My images:

Findings:

	Balloon 1 ( 3 tsp baking soda, ½ cup vinegar)	Balloon 2 ( 3 tsp salt, ½ cup soda)	Balloon 3 ( 2 tsp yeast, 1 tsp sugar )
Balloon Size (cm)	12.5cm	5.2cm	4.5cm
Bubbles	a small number of bubbles	medium about of bubbles	a large number of bubbles

Conclusion: What have I learned from my experiment. The mixture of baking soda and vinegar makes a reaction to each other creating more gas than most other mixes. The mixture of salt and normal soda makes the little amount of gas compared to the baking soda and vinegar. In conclusion, if u want to create more gas I would recommend baking soda and vinegar.

~:Storyboard Creation:~

For art hururmanu, We are creating a stop motion based on manaakitanga. We have decided to create a stop motion movie about kindness because it has something to do with manaakitanga. I'm excited to do this task because I think it will be interesting and very fun. Our story\stop motion is about four girls getting lost in a forest. They use kindness and determination to find there way back and on there way back they stubble across challenges and obstacles on there way back.

Skittles Experiment.

Skittles

Aim: To separate colors from skittles by using chromatography.

Materials;

1. Skittles 
2. Water
3. Petri Dish


Process:

Step 1: Get the dish.
Step 2: Put the skittles in the corners of the dish.
Step 3: Tip the water in the middle.
Step 4: Wait until the color spreads.
Step 5: Then eat them if you please.

Conclusion: What have I learned from this experiment?
That when you mix water with skittles the color gets drained out. When you eat the skittles with no color it taste very very gross.
