This engaging 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. By engaging concept imagery with sensory stimulation in a variety of activities, students anchor their understanding of matter in the form of elements, compounds, and mixtures. Students generalize their understanding by identifying compound and mixtures in their environment.
Sample Classroom Procedure / Teacher Instruction
1. Display a coin, a glass of water, salt, iron, or other examples of elements, mixtures, compounds. Ask students: What do each of the substances have in common? What is different about them?
2. List students’ responses and discuss. Lead the discussion to matter and elements, compounds, and mixtures.
3. Distribute Compounds and Mixtures content pages. Read and review the information with the students. Display and demonstrate some examples of compounds of mixtures if possible. Use the additional resources to enhance understanding.
4. Distribute Activity page. Read and review the instructions. (The activity would be more effective if hands-on activities were used for each type of compound or mixture. Use the additional resources for suggestions.) Give students sufficient time to complete each sketch. Answers may vary but the drawings should match the characteristics for the terms.
5. Once completed, allow student volunteers to display a sketch with an explanation to the class about the term. Students may ask questions or enhance each other’s explanations.
6. Distribute Practice page. Check and review the students’ responses.
7. Distribute the Homework page. The next day, allow students to share examples of compounds of mixtures from home. Check and review responses to questions.
8. In closing, ask: What is your favorite mixture to eat? Why is it a mixture?
9. Allow for responses and discussion.
10. Distribute small bags of M & M’s (or other similar candies. Nuts, etc.) to students. Ask: Why is the candy a mixture? Ask if the mixture can be physically separated.
