Our Compounds and Mixtures lesson plan focuses on the differences between compounds and mixtures, as well as elements. Clarify the three concepts to lay a solid foundation and prepare students for future chemistry-related content. During this lesson, students are asked to sketch given types of compounds or mixtures, clearly distinguishing the differences between each and labeling where needed. Students are also asked to match terms with their definitions, demonstrating their understanding of the lesson vocabulary.
At the end of the lesson, students will be able to compare and contrast a variety of mixtures and solutions such as rocks in sand, sand in water, or sugar in water, demonstrate that some mixtures maintain physical properties of their ingredients such as iron filings and sand; and identify changes that can occur in the physical properties of the ingredients of solutions such as dissolving salt in water or adding lemon juice to water.
