Summer SAVY 2016 (Session 3, Day 2) – What’s the Matter
From hydrophobic sand to sodium polyacrelate and artificial snow polymer, we had a very exciting morning in What’s the Matter! Students began investing the physical properties of two cups of solid particles that looked similar enough but acted in very different ways when introduced to water. After recording our observations on a Venn diagram, we talked about the scientific method and the Wheel of Scientific Investigation and Reasoning. Later in the morning, students continued exploring solids by investigating the physical properties of rocks and minerals. They classified their collections by color, luster, texture, density, and more! We left our artificial snow out to dry and will monitor it over the next few days for changes and will check the sidewalk tomorrow for any signs of salt from a solution we poured out at the end of class today. Tomorrow, students will work with equal arm and triple beam balances, continue to examine change as it relates to the three states of matter, and focus on liquids with some exciting experiments on surface tension!
