Home made Crystals

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

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

Ratio; 3 Tablespoons Borax per 1/2 cup water

Materials

1) pip cleaners

2) string 

3) cup 

4) hot water

5) borax
6) stick

Process

Step 1: grab a polyester cup.

Step 2: put 4 teaspoon of borax.  

Step 3: then put hot water. 

Step 4: then stir the borax in to the hot water.

Step 5: tie the string to the stick

Step 6: tie the pipe cleaner to the string
Step 7: Place the string into the cup

Sugar Crystals

Ratio: 1 cup sugar to 1/2 cup water

Materials

1) sugar. 

2) polyester cup

3) teaspoon

4) hot water 

5) string
6) stick

Process

Step 1: get a  polyester cup 

Step 2: put sugar in the cup

Step 3: put hot water in the cup

Step 4: stir the sugar in with the water

Step 5: tie the string to the stick 

Step 6: set it in the water

Salt Crystals

Ratio: 4 Tablespoons salt to 1/2 cup water

Materials

1) salt

2) polyester cup

3) teaspoon

4) hot water 

5) string
6) stick

Process

Step 1: put salt in polyester cup.

Step 2: then put hot water in the cup.

Step 3: stir it to together.

Step 4: tie the string to the stick. 

Step 5: put the string in the water.

Step 6: then let it set.

Findings

Describe your crystals in the table below.

Crystal Type	Shape (Describe the shape)	Size (of individual crystals)	Hardness (Crumbly to Rock Hard)
Borax	Snow flake,  Frosty.	Madinm.	Brittle.
Sugar	No crystals formed.	Small.	Weak
Salt	Frosty.	Small.	Hard.

What crystals worked out best and why?:

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 Definition:	6	house a box with a pont
Monoclinic Definition:	9	diamond a banker
Orthombic Definition:	5	rectangle
Trigonal Definition:	9	long house.
Hexagonal Definition:	8	tall box tall circle
Cubic Definition:	5	cube Square
Tetragonal Definition:	9	gem from a gam

Explain how the following crystals are formed?

Type
Salt	Soa water, pond, sun, evaporates water and the turns into salt crystal.
Sugar	Sugar cane, chop it up, roll it in to juice, heat elaporate water and then you have a sager crystal.
Snowflakes	Dust,water freezer to dust,  more water freezer to it.

What we are doing for our community

 What is the project 

We are going to go around our Hornby community and pick up rubbish and make art out of it and clean our interment.

Hi welcome back.

What is the purpose of doing this?

Making our interment clean and healthy.

How much rubbish do you think we'll pick up?

At lest over 500 in one or two bags.

What colours do you think we will see the most Why?
Red because it a mean colour to see. green because a lot of people have v's.


What type of art would you like to create?
A bird or a tree with the rubbish we picked up.

baking scons

Aim: To look at different kitchen ingredients in scones and their effects.

Recipe:

• 1/2 cup Edmonds standard flour

• 1 tsp Edmonds baking powder  or 1 tsp baking soda                            

• 2 tsp butter

• 1/4 cup milk, approximately or 1/4 cup lemonade.

The recipes my group chose were:

1. Normal
2. Lemon aid

3. Milk

The other two recipes were:

1. Name: 

Ingredients:

•  baking powder 
•  milk
•  butter

        

       2. Name: 

      Ingredients:

• milk & lemon aid 
• baking powder
• butter
• flour 

Materials:

1.flour2.butter3.flour4.milk5.bowl6.whisk

Process

Step 1: add in tsp of edmonds baking powder
Step 2: add in 1/2 cup of edmonds slandered flour Step 3:2 tsp of butterStep 4: 1/4 cup of milk or lemon aid.Step 5: mix all together.Step 6: put in oven.

TRIAL NUMBER:	COLOUR	TASTE	HEIGHT (CM)
1. NORMAL	white	good	1 and 1/2
2. LEMONADE	white	disgusting	1/3 inches milk and lemonade 1/3 inches
3. milk and LEMONADE	brown	tangy but delicious

Conclusion:
all scones were cooked for 10 minute all scones were cooked at 200 degese

home chemistry: what happens too salt and water

Hi Jessica here my class and other class we have 

AIM: DESIGN AN EXPERIMENT THAT TESTS THE AMOUNT OF SALT THAT MUST BE IN WATER BEFORE IT WILL NOT FREEZE WHEN LEFT OVERNIGHT IN THE FREEZER.

When we design an experiment there are some important questions that we must answer first. This is part of the planning stage and will help to give us some ideas.
Record these answers on your blog.
Task 1; Read the question carefully and write the answer to these questions. 

1. What do we need to find out? what will happen to salt and water when there  freeze.
2. How will we find it out? do it home do at a friend do it where your staying at  
3. How will we record what we find? do it on your blog or on paper
4. What equipment do we need for the experiment? a cup, a measuring cup, salt, water and a freezer 
5. How long will it take? 1 to 2 night

Task 2: What are the steps that you will take to make the experiment?
List them in 6 steps.
Step 1; get a cup
Step 2: get a measuring  cup 

Step 3: measure the salt

Step 4: measure the water

Step 5: then put it in the fezzer 
Step 6: wait 1 or 2 night 

Task 3: Draw on a piece of A4 paper the 6 steps that you will use to test the amount of salt in water before freezing. When we are making drawings in science  it needs to be labelled clearly, kept tidy and named. Once you have completed the drawing it must be photographed and uploaded to your blog.
In your drawing you will use:

1. Beakers

1. Water

1. Measuring spoons or cups

1. Salt

my mum said it wont freeze  but it did and i was surprise it did freeze.

ATHLETICS DAY

Welcome back. I'm going to till you about me athletics day we had yesterday.

We left class at 10:15 to go to our house in my house our colour was green I had green all over me. Then we went out to the filed it was so hot and I was burning so much I was late for my first event. 

At interval I was trying to look for my second event but I couldn't find it so I was late.  I just waited in till I was discus then when it was discus I went over to discus it was fun I got pretty far then what i did in primary school.


Near the end of the day I did long jump it was really fun as has much as i enjoy long jump i wanted to do better. We had to line up in our colour group Then some people did relays it so cool to watch the fast people go.  

Thank for reading my blog have a good day.
