Students consider density and how it affects sinking and floating. Students make predictions, test liquids, and observe why some liquids sink and others float. They perform experiments to determine relational causality and how liquids layer. They also apply relational causality to liquid layers. Full Review »

Students apply knowledge about density of solids from previous experimentation to this activity which they investigate the density of liquids. They work in small groups to mix water and syrup, and water and oil to see what occurs. Finally, they complete a worksheet and discuss the results of the experimentation. Full Review »
