Crystal


Introduction:In science yesterday we made sugar crystals from homemade syrup, we put sugar on the sticks to make a surface for the crystals grow. 

Aim: The aim is to make sugar crystal to grow from the Popsicle stick and to see what they taste like when they are finished and eat it.

 Method 
In a beaker ,heat at lest 250 g of sugar together with 50 ml of water.

  1. Dissolve the sugar in the boiling water.
  2. Allow the solution to cool a bit before pouring it into your jar. 
  3. Pour the sugar mixture  into a jar. Place a wooden skewer into the jar or else hang a string into the middle of the jar, tied to a pencil or butter knife.
  4. Place the container somewhere it won’t be disturbed.Cover the jar with a paper towel or coffee filter to allow evaporation.
  5. It may take a few days for the crystals to start to grow  If you see crystals forming on the top of the jar, you can remove them and eat them. If you leave them, these crystals will compete with your stick or string for sugar and will reduce the size of your crystals.
  6. Remove the crystals and enjoy them! If you want to store the crystals before eating them, keep them in an airtight container so humidity in the air won’t make the rock candy sticky
3. the mixture is separating by sugar forming on the string or the stick leaving the liquid in the jar. 

Discussion: Making crystal can septet a solid from a liquid  hawere a highly concentrated solution way needed (  satiated solution in order to grow ays  tong.

  1. Hey Rojan,
    This looks like a really fun experiment. Your method is clear and easy to follow. Your post made me wonder if you had achieved your aim? Did you get to taste them? How did your one turn out? It would be great if you could edit your post to include this information.
    I look forward to hearing from you,
    Miss Morgan
