Home Chemistry: Crazy Crystals (Pt 1)

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)

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) Water 

4) Something to stir with (Etc, Stick or Spoon)

5) String 

Process

Step 1: Get a cup. 

Step 2: Pour in warm water. 

Step 3: Pour in the amount of borax needed.

Step 4: Mix until saturated ( or for around 10 mins)

Step 5: Get a peg, make a star out of pipe cleaners.

Step 6: Then hook it on the cup. 

Sugar Crystals

Ratio: 1 cup sugar to 1/2 cup water

Materials

1) Sugar 

2) Warm Water 

3) Stick

4) String 

5) Cup 

Process

Step 1: Get a cup.

Step 2: Pour in warm water.

Step 3: Pour in the amount of sugar.

Step 4: Mix until saturated ( or for around 10 mins)

Step 5: Get a stick 

Step 6: Tie the string into the stick and push the string down solution.

Salt Crystals

2) Cup 

3) String 

4) Stick 

5) Warm Water 

Process

Step 1: Get a cup.

Step 2: Pour in warm water.

Step 3: Pour in the amount of salt.

Step 4: Mix until saturated ( or for around 10 mins)

Step 5: Get a stick
