Big Idea:Students have a general sense of how matter changes forms but their understanding of other properties of matter need more development. This lesson gets students thinking about density as a property of matter.
Big Idea:Now that students can visually represent and explain the basic molecular factors within a certain volume that determine density, it is time for them to measure mass and volume to calculate density.
Big Idea:Evidence-based explanations derived from evidence-based argumentation can happen only if students collect their own data. This lesson gives students time to manipulate various characteristics of matter to deepen their understanding of density.
Big Idea:Giving students time to analyze data, develop arguments, listen to others' arguments can lead to deeper understanding. Using evidence to support claims is a crucial part of science and is used here to deepen students' understanding of density.
Big Idea:Bringing learning alive with visuals is especially important when students are developing a deep understanding of density. In this lesson, students will draw molecules to help explain why some cubes sink or float, based on their density.
Big Idea:Students have dealt with solids and placing them in water, but they haven't looked at the density of liquids. This lesson has students think about the factors that lead to various phenomena, like separation and floating in different liquids.
