Sugar Crystals

Yesterday in science we made some sugar crystals.

Ingredients: Food colouring, Sugar, Water.

Equipment: Popsicle sticks, Beakers, Gauze mat, Heating mat, Tripod, Bunsen Burner, Gas tap, Stirring Rod.

Method: 1. Pour approximately 50 ml of water into a 250 ml beaker,
              2. Pour 250g of sugar into a beaker. Bit by bit. 
              3. Light the Bunsen burner with the beaker on the tripod.
              4. Once the water was boiling we turned off the Bunsen burner.
              5. After we turned the Bunsen burner off, we started stirring the sugar with a stirring rod.
              6. Once we finished stirring we poured the syrup into plastic cups.
              7. We then coated the Popsicle sticks with the left over sugar and put them into the syrup.
              8. Once we done that we left them on the windowsill overnight.  

I learnt that if you put in too much water it will stay as a liquid and if you add too much sugar then it won't set properly. Making Crystals can separate a solid from a liquid. A highly concentrated solution was needed ( Saturated Solution) in order to grow Crystals.

  1. Hi Cole, this is a great blog! You went into good detail in your method about how you completed this experiment. You were really specific in your steps, someone else could give this a go. Also your comment about learning growing crystals was separating a solution showed your understanding. Next time could you please update you blog once after you let the experiment rest for a week. Please publish all your blogs, thank you.

  2. Hey Cole,
    This looks like an interesting experiment. Thanks for sharing the method - I will be careful to not add too much water... I wonder how did yours turn out? Did you get to eat it at the end?
    Look forward to hearing from you,
    Miss Morgan
