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) 

Borax Crystals

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)Cup

2)Borax

3)Popsicle Sticks

4)warm water

5) pipe cleaners 

Process

Step 1: Get a cup and put three tablespoons of borax

Step 2: put warm water in the cup and take a stick and stir it until it looks like a solution 

Step 3: wait for a while and keep an eye on it 

Step 4: after a while stir it again and if it feels like there is still mush that normal 

Step 5: stir for a while if it just feels thick stir faster but try not to spill it
Step 6: once you think you've stirred enough stop and let it rest and keep an eye on it 

Sugar Crystals

Sugar crystals video

Ratio: 1 cup sugar to 1/2 cup water

Materials

1)Cup

2)Sugar

3)Popsicle Stick

4)Warm water

5)String

Process

Step 1: take your cup and add sugar until it is halfway full 

Step 2: Put the warm water in and start to stir 

Step 3: stop stirring and wait for awhile keep eye on it

Step 4: stir it once again and do it fast not to fast that you spill it

Step 5: wait for 5 minutes 

Step 6: stir it until it becomes a yellow see-through liquid  

Salt Crystals

Salt crystals time-lapse video

Ratio: 4 Tablespoons salt to 1/2 cup water

Materials

1)Salt

2)Popsicle sticks

3)Cup

4)Warm water

5)String

Process

Step 1: take your cup and add four tablespoons of salt 

Step 2: Put the warm water in and stir for a while

Step 3: wait for 5 minutes

Step 4: stir fast and keep an eye on the color  

Step 5: after the wait and you see there is water at the top and salt at the bottom and you can see the separation that is normal

Step 6:stir for 10 minutes then wait for 5 minutes 

Findings

Describe your crystals in the table below.

Crystal Type	Shape (Describe the shape)	Size (of individual crystals)	Hardness (Crumbly to Rock Hard)
Borax	Cubic	Small, Medium	Hard
Sugar	Trigonal, cubic
Salt

What crystals worked out best and why?:

Conclusion:

________________________________________________________________________

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

Type	Explanation
Salt	people take the water from the ocean and put it into a pond,so when it's a hot hot day the water will evaporate and all that will be left is the crystals
Sugar	people take cups and water then they add sugar to it until it goes a clear-ish yellow and they take a stick and put a string on it and puts in sugar then puts it in the water and they wait a few days to see what happens
Snowflakes	snowflakes are made from clouds because clouds have crystals in them and thats how rain and snowflakes are made the crystals are made from water

CRYSTAL TYPES

AIM: TO LOOK AT THE 7 DIFFERENT TYPES OF CRYSTALS

Salt Crystals

Sugar Crystals

Borax Crystals

7 different crystal shapes

The 7 types of crystals

Type	Number of sides	2 examples	Image
Triclinic	7	Turquoise Rhodonite
Monoclinic	8	orthorhombic
Orthorhombic	6	olivine
Trigonal	9	albite
Hexagonal	8	Quartz,
Cubic	6	pyrite,
Tetragonal	12	rhodonite . gypsum

Home chemistry - Balloons

Aim: To see which chemical

the mix creates the most gas.

Hypothesis: (What do I think will happen)

I think that the vinegar will have more bubbles because of the different types of chemicals inside of it.

Materials:

1. Bottle
2. Balloons
3. Vinegar ½ Cupid
4. Baking soda 3 tsp
5. Salt 3 tsp
6. Soda

Steps:

1. First you put the liquid inside of the bottle.(Vinegar and Soda)
2. Then put the dry ingredients in the balloon.(Baking soda and Salt)
3. Then you put the tip of the balloon on the tip of the bottle then you lift the balloon up straight therefore tipping the chemical into the bottle.

My images:

Solutions:

	Balloon 1 ( 3 tsp baking soda, ½ cup vinegar)	Balloon 2 ( 3 tsp salt, ½ cup soda)
Balloon Size (cm)	8cm	4cm
Bubbles (small, medium, large)	Large.  More air got into the vinegar bottle other than the salt bottle.	None. There were hardly any visible bubbles.

Drama Activities - Freeze frame

Drama Activities - Freeze frame

Our aspect of Hauora was:

• Today we focused on four well-being aspects of Hauora, We got selected into teams including four or five members. We had a team of four and we had to come up with a freeze frame  representing Mental Well-being.

What we did in our freeze frame was?

• Our group and I , we demonstrated a structure of us being angry at each other, and we had to look at each other and use our angry faces not only that but we had to express our angryness by using our words.

Captions: Our caption was?

 

For our captions I had to say “I hate it when you make fun (mock) my hair” “and I thought it was a joke.. And it made you angry”

Found a Drama game I would like to play?

• I've had a look at the linked that was attached and I liked the game called Pukana (Maori traditional game)
• I think this game can help us in drama because we have to use face expressions just like we have to when we're acting or performing based on the genre of what were doing.

Include the 4 aspects of Hauora:

Taha Wairua (spiritual Well-being)

1. Personal Belief Structure
2. Purpose in life
3. Goal setting
4. Being true to yourself
5. Values
6. Cultural Values
7. Mixing with others

Taha tinana (physical Well-being)

1. Health benefits
2. Strength
3. Weight management
4. Flexibility
5. Work rate
6. Feeling fresh and healthy
7. Team strategies
8. Expression

Taha whanau (Social Well-being):

1. Friendships
2. Social interactions
3. Helping others
4. Being included
5. Compassion caring
6. Spending time with family

Taha hinengaro (mental and emotional health):

1. Including others
2. Sense of achievement
3. Communication thoughts and feelings
4. relationships
5. Problem Solving
6. Decision making

are a solid, liquid or a gas.

 

Equipment:

1. Soap

2. Lemon juice

3. Salt

4. Vinegar

5. Sugar

6. Milk

7. Onion

8. Lemonade

9. Bleach

10. Baking Soda

Steps:

1. Add the name of the ingredient into the chart
2. Search for an image of the ingredient
3. download and paste in into the chart
4. Search for the chemical used in the ingredient
5. Find out if the ingredient is a Solid, Liquid or Gas

Task 1: Put the 10 chemicals in a chart with the titles - Name, Chemical
ingredient(s), Image, Solid/Liquid/Gas.

Name	Chemical	Image	Solid/liquid/gas
Lemon Juice	Citric Acid		Liquid
Salt	Sodium Chloride		Solid
Soap	Sodium		Solid
Sugar	Table sugar		Liquid
Vinegar	Acetic acid		Liquid
Milk	triglycerides		Solid
Onion Gas	Sulfur gas		Gas
Bleach	Sodium hypochlorite		Liquid
Baking Soda	Sodium hydrogen carbonate		Solid
Lemonade	Fructose		liquid

Conclusion:

For today's task I've learnt what a liquid, gas and solid is, and I've also learnt new
chemicals that I've never heard of before.
