Volcano Recipe Worksheet

Below are the directions you must follow to successfully create your volcano recipe. Show all of your calculations and final ingredient measures on a separate sheet of paper.

 

Step 1:

Combine the following ingredients in a large bowl.

cups of salt

cups of flour

table spoons of Cream of Tartar

 

Step 2:

Once you have mixed the above ingredients thoroughly, add the following ingredients. You will need an adult to help you adding the last ingredient.

cup of vegetable oil

drops of yellow or green food coloring

cups of boiling water

 

Step 3:

Mix all of these ingredients together and let the mixture cool.

Once your mixture has cooled, cover a work area with newspapers. Then take a

small plastic soda bottle and mold your dough around it to form your volcano. Be sure to leave an opening at the top for your lava to seep out. Fill the bottle full of water and then add two to three drops of red food coloring.

 

Step 4:

Use a funnel to add the following ingredients to the bottle in the exact order they are given.

drops of liquid detergent

tablespoons of baking soda

 

Now, very slowly pour in a small amount of vinegar until your volcano erupts.

So, did your mystery mixture work properly? If not, go through your calculations again to see if you made a mistake.
