Vulcões

Experiência do vulcão

Material necessário:

  • 1 frasco

  • 1 prato

  • argila

  • bicarbonato de sódio

  • corante

  • vinagre
  • Coloque o frasco sobre o prato. Cubra o frasco com argila, modelando-o com formato de um vulcão. Encha até a metade do frasco com bicarbonato de sódio e coloque um pouco de corante alimentar. Coloque o vinagre sobre o bicarbonato.

    A mistura começou a fervilhar derramando-se pelas encostas do vulcão.
    Pode-se fazer essa experiência em grupos ou uma única experiência para a turma toda observar.
