In a just single teaspoon of soil there are around 5 million single celled organism!

Materials: 1. A wooden skewer 2. A clothespin 3. 1 cup of water 4. 2-3 cups of sugar 5. A tall narrow glass Steps: 1. First, clip the skewer into the clothespin so that it hangs down inside the glass and is 1 in from the bottom of the glass. 2. Next, remove the skewer and clothespin and put the aside. 3. Then, pour the water into a pan and boil it. 4. Next, pour 1/4 cup of sugar into the boiling water and stir till it dissolves. 5. Then, keep adding more sugar, each time stirring until it dissolves. 6. Next, remove the heat and allow it to cool for 20 minutes. 7. Then, ask an adult to pour the mixture into the jar to the top. 8. Next, submerge the skewer into the glass so it is hanging straight down the miss without touching the sides. 9. Finally, put it somewhere where it would not be disturbed and wait for the sugar crystals grow over the next 3-7 days. Lesson: When you mix water and sugar, you created a saturated mixture, which means that the water could only hold the sugar if it was very hot. As the water cools, the sugar turns into crystals on the skewer.

GIF Tip: Build a Potential Energy Vehicle 

Create a vehicle that stores potential energy, then converts it to kinetic energy. A fundamental law of Physics is that energy is never created or destroyed, only changed from one form to another.
