SNOW STONE CRYSTALS
Students are excited to start a new exploratory science project. Snow Stone crystals (donated by Gage's family) from the famous cliffs of Dover, England and the Rock of Gibraltar are made of the same rock as Snow Stone. The crystals that form on Snow Stone occur naturally in many places in the world. By adding vinegar to cover the stone for the next 3 weeks we will observe it evaporate. The vinegar liberates carbon dioxide and water trapped in the rock. Through chemical reactions, beautiful and delicate calcium acetate crystals form.
DAY 1 Students observed the reaction to vinegar, although not much change occurs.
DAY 3 Already crystals are beginning to form and the rock has expanded. The crystals form "peaks" and are beginning to take shape. Students discuss the changes in the rock formation and predict growing patterns for the crystals.
We will chart and observe the crystals daily. Make sure to come check them out yourself and we will continue to post pictures of the developing crystals. Thanks again to Gage's family for such a great science project!
