The Fifth Grade is currently working on the unit, Modeling Matter
This Unit includes three chapters. In the role of food scientists, students work to identify a potentially hazardous food dye in a food coloring mixture, then to create a good-tasting and visually appealing salad dressing. They engage in hands-on investigations and use physical and digital models to gather evidence about mixtures at the observable scale and at the scale of molecules. They develop visual models and write explanations about mixtures, including whether they are likely to change or remain stable.
Chapter 1: Why did the food coloring separate into different dyes?
Chapter 2: Why do some salad dressings have sediments, and others do not?
Chapter 3: Why can salad-dressing ingredients separate again after being mixed?
