DIY 1 Ingredient Rock Candy Tutorial From Growing A Jeweled Rose. When Listing Ingredients I Do Not

Flamboyant Cuttlefish by  Beyond The Water Surface

Materials: 1. Baking Soda 2. Vinegar 3. A Container to Hold Everything 4. Baby Food Jar 5. Red food coloring 6. Liquid dish washing soap 7. Clay Steps: 1. First, create a cone/ volcano shape out of clay. 2. Next, put the jar into the volcano at the top. 3. Then, add 2 spoons of baking soda 4. Next, add a spoon of dish soap 5. Then, add 10 drops of the food coloring. 6. Finally, add an ounce of vinegar into the container. Lesson: The baking soda is a base while the vinegar exist as the acid for the experiment. When they react, they create water and carbon dioxide. The reason the "lava" fizzes is because the carbon dioxide is escaping from the solution.

Bill Nye, “The Science Guy”, has some great “home demos” which could certainly be used in the classroom, along with some printable “one sheets”.

Home Demos are found in three categories; life sciences, physical sciences, planetary sciences.

That is what it looks like it you try to burn biscuits straight out of the packet.

This is what it looks like if you try to burn biscuits after you soak them in liquid oxygen:

Adding liquid oxygen means that the biscuits (the fuel in this reaction) can burn to their full potential. When you just burn them in air, there isn’t enough oxygen (one side of the fire triangle of heat, oxygen and fuel), and that limits the reaction.

Just plain cool.

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 ¼ 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.
