Explain how the following crystals are formed?


Type

Salt
As the water evaporates from the solution, atoms bond together. The also molecules bond together forming crystals. Every molecule will form the same shape every time it forms.

Sugar
While the water evaporates, the solution becomes saturated and sugar molecules will continue to come out of solution. The crystals grow by molecule by molecule.

Snowflakes
A snowflake forms when an extremly cold water droplet freezes onto a pollen or dust. This will create an ice crystal, and when the ice crystal falls to the ground. The water vapour freezes onto the primary crystal, building new crystals.

Crystals

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

Definition of a 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)

Borax Crystals: 

Image result for borax crystals

Materials:

1. Pipe cleaners
2. Hot water
3. Pegs
4. Spoon 
5. Container/Cup
6. 8 tsp Borax

Process: 

Step 1. Put 8 tsp amount of borax to your container/cup. 
Step 2. Pour hot water to the container don't fully fill it.
Step 3. Grab your spoon and stir. 
Step 4. When the borax has mixed with the hot water, take the spoon out and get your pipe cleaners and pegs.
Step 5. Make a star using your pipe cleaner.
Step 6. Clip the peg onto one of the legs of the pipe cleaner, hang the peg downwards so the pipe cleaner is hanging.

Sugar Crystals:

Grow your own Sugar Crystals

Materials:

1. Container/Cup
2. 8 tsp Sugar
3. Spoon
4. Pegs
5. Hot water 
6. Pipe cleaners

Process:

Step 1. Just like the borax crystals put 8 tsp amount of sugar to your container/cup.
Step 2. Pour hot water to the container don't fully fill it.
Step 3. Grab your spoon and stir.
Step 4. When the sugar has mixed with the hot water, take the spoon out and get your pipe cleaners and pegs.
Step 5. This time just clip the peg to the pipe cleaner.
Step 6. Hang the peg downwards so the pipe cleaner is hanging.

Salt Crystals:

Materials:

1. 8 tsp Salt
2. Pipe Cleaners
3. Container/Cup
4. Hot water
5. Spoon
6. Pegs

Process: 

Step 1. Just like the borax and sugar crystals. Put 8 tsp amount of salt to your container/cup.
Step 2. Pour hot water to the container don't fully fill it.
Step 3. Grab your spoon and stir.
Step 4. When the sugar has mixed with the hot water, take the spoon out and get your pipe cleaners and pegs.
Step 5. Just like last time just clip the peg to the pipe cleaner.
Step 6. Hang the peg downwards so the pipe cleaner is hanging.

What crystals worked out best and why?:

The borax had the most crystals and the salt had a little bit but it was crumbly. The sugar didn't have any crystals. The borax saturated more that's why it had the most crystals in it. If the sugar was more syrup like it would have made crystals. Although our one wasn't syrup like that's why it didn't work.

Scones

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

In groups of 4 you will: 


  • Make 4 types of scone. 
  • Normal plus 3 others.


1. No butter,
2. No Baking Powder
3. No milk
4. With Lemonade
5. With Baking Soda

Recipe for normal scone:

  • Milk
  • Baking Powder
  • Flour
  • Butter


Recipe for lemonade scone:

  • Lemonade
  • Baking Soda
  • Flour
  • Butter


Recipe: Baking Soda

  • Milk
  • Baking Soda
  • Flour
  • Butter


Materials: 

1. Bowl
2. Butter
3. Baking Flour
4. Milk
5. Flour
6. Baking Powder
7. Lemonade

Process: Normal Scones

Step 1: Get your bowl and add 1/2 cup of baking powder.
Step 2: Add 1 tsp of baking soda.
Step 3: Add 10g of butter.c
Step 4: Add 1/4 amount of milk on the bowl with the dry ingredients, add more milk if needed.
Step 5: Mix all ingredients, until you have the right consistency.
Step 6: Put dough in the oven.

Findings:



TRIAL NUMBER:

COLOUR

TASTE

HEIGHT (MM)

1. NORMAL

Pale yellow Creamy, A bit softer, a bit bland.42mm


2. NO BAKING POWDER

Brownish Raw in the middle, very floury, and has a weird taste.47mm

3. WITH LEMONADE

WhiteFloury, tangy, you can taste a little bit of lemonade but not much.44mm


Conclusion:
The scones were cooked for 10 minutes at 200o Celsius. The other recipes didn't taste really good, the worst scone for me was the scone with no baking powder. It was raw and very floury and didn't taste very good, it had a brownish colour and was 47mm high. The lemonade scone and was not so good either however it wasn't the worst one. It was colour white with a flory, tangy taste. I tasted a little bit of lemonade but not that much, it was 44mm high. The normal was the best scone because there was nothing added to it or removed. The colour of it was pale yellow and was a bit creamy, and softer. But it was also bland. The height of the normal scone was 44mm.
