Snow Volcano Science Experiment

The volcano science project is one that is a classic for a reason. It’s simple, requires only common ingredients, but it’s eye-catching enough to delight any kid. In this activity, kids learn about endothermic reactions (because the reaction is cooler than the original materials), chemical reactions, acids and bases, and the basics of the scientific method. How does the amount of snow you use or the kind of snow you use affect the reaction? These questions can start as the jumping off point for your snow volcano science experiment.

Little science lovers will have a blast making this snow volcano science experiment. Do it outdoors in the snow, or make your own snow!

You can do this experiment outside in the snow, bring snow inside for the activity, or make your own snow!

If you make your own snow, use this recipe:

DIY SNOW RECIPE

Mix one part baking soda with one part cornstarch. Mix.

Add just enough water so that when you squeeze the snow, it crumbles in your hand and holds a shape.

Once this texture is reached, your snow is ready!

Form the snow into a volcano shape with your hands.

Fill the cavity with baking soda, red food coloring, and a squirt of dish soap.

Use a dropper to squeeze vinegar into the cavity a little at a time. Watch as the volcano erupts and red liquid spills over the side of the snow. Your snow will also start to melt once the reaction occurs, but that’s all part of the fun! Keep adding vinegar until the mixture no longer reacts or until your snow is completely melted.
