Idyllwild Montessori School on Instagram: "IMS Science Fair project - Volcano Eruption. A Montessori volcano eruption is a classic hands-on science experiment using baking soda, vinegar, food coloring, contained in a special volcano model, demonstrating the chemical reaction that creates gas and "lava" foam, teaching earth science, chemical reactions, and encouraging observation. We also watched a real volcano eruption video, so our students address it to the experiment. #volcanoeruption #scienc
