With this volcano experiment, your child will be hooked on chemistry after she builds a model volcano by combining an acid and an alkaline substance!
Supplies: Empty water bottle, 1 or 2 boxes of baking soda, vinegar, red and blue food coloring, dinosaur figurines, salt dough (here is a great recipe), dish soap, a big container and a small one.
Step 1: Fill the empty water bottle with warm water until there is only about 2 inches left empty at the top. Mix red food coloring into the water.
Step 2: Make salt dough (optional) and cover the water bottle with it. Mold it into the shape of a volcano.
Step 3: Fill the small container with vinegar and blue food coloring.
Step 4: Place the water bottle volcano in the big container and cover the bottom with a lot of baking soda, but save some for later, too. Place the small container full of vinegar and blue food coloring in the big one.
Step 6: Let your kids play around with the dinosaurs. After they have played for a bit, pour vinegar and baking soda into the top of the volcano. The kids will have a blast pretending to run away from the “lava”. Our kids loved to bathe the dinosaurs in the blue “pond” and then plop them in the baking soda sand. This project is easy and will entertain your kids for hours!
