Note Experiment on how to make a Volcanic Eruption

YAIN STEAM CONSULTS

EXPERIMENT: VOLCANO ERUPTION

Objectives:

· The children will learn about the various states of matter: Solid, Liquid and Gas

· They will investigate the differences between them by comparing various materials that exist naturally in these states.

· They will further discover that some materials change their states when heated as well as react when mixed with other materials.

· They will create their own model of an erupting volcano using the reaction of different materials mixed together.

Volcanoes erupt when molten rock called magma rises to the surface. As the magma rises, bubbles of gas form inside it. As magma rises through many kilometres to the Earth's surface, dissolved gases contained within it form expanding bubbles. These bubbles increase the pressure of the magma and, if this pressure is great enough, the volcano will erupt.

Ingredients:

· Plastic cup Water

· 3-4 Tbs of baking soda at least (we usually do 4-6 which makes it extra foamy and will do 2-3 eruptions)

· 1 tsp of dish soap

· 1/2 oz to 2 oz of Washable Paint📷, depending on the intensity of the color desired

· 1 cup (8 oz) of Vinegar to start with per eruption…then they’ll be asking for more

Instructions:

· Start off by combining the “base ingredients.” Put the water inside of the plastic cup. Fill it about 2/3 full.

· Add the baking soda, dish soap, and washable paint📷. By using washable paint, you don’t have to worry about any staining on the rocks (or little fingers)

· We give it a good stir just before adding the last ingredient.

· Now it’s time for the eruption! Pour in the vinegar until it starts foaming over, pouring its lava all over the rocks.
