Home Chemistry - Crazy 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


Borax Crystals

Materials


1) 3 tablespoons of Borax
2) ½ cup of Warm liquid/ Water
3) Container
4) Spoon
5) Paper
6) 3 x 10 centimeters of pipe cleaners
7) Peg


Process


Step 1: Make a star out of 3 pipe cleaners by crossing them over.
Step 2:Add a peg by clipping it on to the star.
Step 3:Place 3 tablespoons of borax in a container.
Step 4:Add ½ a cup of warm water into the container by pouring it in.
Step 5:Stir the solution with a spoon for 5 minutes.
Step 6:Place the star that you have made previously and make it so the peg is sitting up the top of the cup so the pipe cleaner star is in the solution


Step 7: Write your name of your group and then write on your container what is in the container.  


Sugar Crystals


Grow your own Sugar Crystals


Materials


  1. 6 tablespoon Sugar
  2. Spoon
  3. Container
  4. 7 centimeters of a Pipe Cleaner
  5. Peg
  6. Hot liquid/ water


Process


Step 1: First get a 7 centimeter long pipe cleaner and attach it to a peg .
Step 2:add 8 tablespoons of sugar to the container.
Step 3:then add ½ a cup of hot liquid to the sugar.
Step 4:stir the solution till the sugar is dissolved.
Step 5:then get the pipe cleaner and the peg and place it at the top of the cup.
Step 6: Place your container on the paper you wrote on before.

Salt Crystals

Materials


  1. 3 teaspoons of salt
  2. ½ a cup of hot liquid/ water
  3. Spoon
  4. Container
  5. Pipe cleaner
  6. Peg


Process


Step 1:place a peg on a 10 centimeter pipe cleaner.
Step 2 Add 3 tablespoons of salt to a container.
Step 3: Then add ½ a cup of hot liquid to the salt.
Step 4: Mix the solution for a few minutes.
Step 5:Then add the peg and pipe cleaner into the container.
Step 6: Place your work on the piece of paper.

What crystals worked out best and why?: The borax one did because the others did not work.
we didn't mix or put much of ingredients in to the sugar and salt recipe.
we did saturate the borax one more than we did in the salt and sugar.

 2: Orthorhombic.
 3: Monoclinic.
 4: Triclinic.
 5: Trigonal.
 6: Hexagonal.

Task 2 and Task 3
Compounds
Method
Observation of reaction
Why does it react that way
  1. Baking soda
  2. Vinegar
A teaspoon of the baking soda
was placed in a cup. 3 teaspoons
of vinegar were then placed into the cup.
The mixture bubbled, fizzed
and overflowed.
Why does it react like that ? It reacts that way because the acid in the baking soda reacts to one of the chemicals in the vinegar.
  1. bleach
  2. Baking soda
1/2 cup of baking soda is added to a typical laundry load with bleach
It fizzes a little but it also becomes a better cleaning product.
It has that kind of reaction because the baking soda has a sort of acid in it that reacts to a chemical in the bleach.
  1. Lemon juice
  2. Baking soda
3 tbsp of lemon juice and 2 tsp of baking soda in a glass and watch the reaction.
The reaction was that it bubbled/fizzed up but it is good for sores .
In lemon juice there's a percentage of citric acid and the acid in the baking soda clashed with the acid in the lemon juice.
  1. Dish soap
  2. Vinegar
Place a 1\4 of vinegar and dish washing liquid in a spray bottle put the lid on and shake.
It just ended up bubbling and is good for cleaning products.
It didn’t fizz this time itn only bubbled because in the dish soap there isn’t any baking soda or citric acid  
  1. Lemon juice
  2. Sugar
Put 2 tsp of lemon juice in 3 tbsp of sugar in a cup.
There was only a little bit of fizz this time but it made a good ointment.
It  didn’t react like the rest because the sugar isn’t the same as the baking soda because it has no acid in it .
