[KIDS] Vocabulary Word of the Week: Solution

The vocabulary word of the week is solution. A solution is a special type of mixture. To make this mixture, a solute dissolves in a solvent. In this DIY, our solute is sugar, and the solvent is water. This means that the sugar will dissolve in the water. But by the end, you will have a sweet treat to eat! This activity includes some hot liquids, so make sure to work with an adult.

Materials:

  1. A wooden skewer or chopstick

  2. A clothespin

  3. Pot to boil water

  4. 1 cup of water

  5. 2-3 cups of sugar

  6. A spoon

  7. A narrow, tall jar or glass

  8. Food coloring (optional)

Method:

  1. Clip the clothespin around the skewer. The skewer should be able to hang about one inch above the bottom of the jar. Put it aside for now.

  2. Pour water into the the pot and bring it to a boil.

  3. Wait for the water to boil. Then pour about ¼ cup of sugar into the water. Start stirring and continue to stir until it dissolves.

  4. Continue to add more sugar and to stir till it dissolves. Continue to add more amounts of sugar until no more will dissolve. This process takes time and it will take longer for the sugar to dissolve each time. Be patient!

  5. When no more sugar will dissolve, remove the pot from the heat. Allow it to cool for about twenty minutes.

  6. Pour the sugar solution into the glass, almost to the top. If you want, you can mix in food coloring to make your candy colorful!

  7. Using the skewer and clothing pin, dunk the skewer into the solution and place the pin on top of the rim so that the skewer is not touching the bottom or sides.

  8. Allow the jar to fully cool. Make sure to put it in a place it will not be disturbed

  9. Now it’s time to wait. The sugar crystal will grow over the next 3-7 days. Then it will be ready to eat!

How does it work?: By heating up the water, you allowed it to hold more sugar than it normally can. This is called a supersaturated solution! When the solution cools down, the sugar that was dissolved in the water is “pushed out” of the solution, because cool water can’t hold that much sugar. This is why sugar crystals begin growing on the wooden skewer.
