We transitioned from solids to liquids by discussing how ice and water are two forms of the same substance. We then voted on whether water set outside in freezing temperatures would freeze before the ice cubes would melt in the classroom under a heat lamp.
We also discussed what makes up a mixture (all parts remain whole), a solution (such as salt dissolving into the solvent, water) and saw two liquids that just do NOT mix!
Sand and water makes wet sand...No dissolving here!
Buttons? No dissolving here!
Oil and water? One of our friends pretends to drink this crazy combination!
Our friends are becoming very talented at recognizing liquids. They worked in teams to draw and label all of liquids we use everyday! One team came up with over 40 common liquids!
