Last week the some members of the class were able to help construct a mini volcano out of clay. Over the weekend, the clay hardened and it was the perfect consistency to use. The children gathered together; Mrs. Turner carefully demonstrated pouring vinegar through a funnel into the volcano; a drop of red dye was added, as well as a teaspoon of baking soda. Suddenly, eyes widened and grins appeared as the chemical reaction began to fizz and shoot out of the top of the volcano, the only part missing was the extream wave of heat that would come with the lava flow. Following the group presentation, the work was available for the children to work on individually.
The children are also learning about the
parts of a volcano through books, puzzles and three part matching cards.
The TMA Science Fair will feature this experiement along with Growing Crystals, Gloop, Sink or Float, and Magnetic or Nonmagnetic from the other early childhood classrooms.
