Debbie had a bottle covered in clay to look like a volcano, which we partially filled with some baking soda ahead of time. When she poured in vinegar (dyed red), the chemical reaction had "lava" flowing out of the vent hole. Oh my goodness were the kiddos excited!
We followed up our reading, singing, dancing and demonstration, with science and art activities that also stretched our fine motor skills. To make our volcano diagram, the kiddos tore construction and tissue paper, glued them, wrote their names, and then cut and pasted labels for some of the important parts of a volcano: magma, vent hole, ash, and lava.
(The label for magma is on the back, because it is only magma while it is underground. As soon as it emerges from the vent hole it is called lava.)
We had fun sorting out things that are hot (like a volcano) and things that are cold.
The highlight of the whole time was definitely letting the children build their own pebble volcanoes, and mixing baking soda and red vinegar. They wanted to do it over and over - and with almost 60 children attending this week, we used 3/4 gallon of vinegar, and 4 pounds of baking soda!
The awe on their faces was worth every drop!
