In this activity, students will create detailed definitions of vocabulary terms related to mixtures and then organize them into a hierarchy. Students will collaborate with peers to classify real world examples of mixtures as solutions, suspensions, or colloids and justify their classifications in writing.
|5th Grade||5-PS1-3 – Make observations and measurements to identify materials based on their properties.|
|5-PS1-4 – Conduct an investigation to determine whether the mixing of two or more substances results in new substances.|
|Middle School||MS-PS1-2 – Analyze and interpret data on the properties of substances before and after the substances interact to determine if a chemical reaction has occurred.|
|5th Grade||CCSS.ELA-Literacy.W.5.2 – Write informative/explanatory texts to examine a topic and convey ideas and information clearly.|
|CCSS.ELA-Literacy.W.5.10 – Write routinely over extended time frames (time for reflection and revision) and shorter time frames (a single sitting or a day or two) for a range of discipline-specific tasks, purposes, and audiences.|
|Middle School||CCSS.ELA-Literacy.WHST.6-8.1 – Write arguments focused on discipline-specific content.|
|CCSS.ELA-Literacy.WHST.6-8.10 – Write routinely over extended time frames (time for reflection and revision) and shorter time frames (a single sitting or a day or two) for a range of discipline-specific tasks, purposes, and audiences.|
Students will be able to define vocabulary terms related to mixtures and organize them into a hierarchy.
Students will be able to classify real-world examples of mixtures as solutions, suspensions, or colloids and provide justification for their classifications.
• Building Blocks of Chemistry series, specifically Mixtures and Solutions
• Mixtures hierarchy example (for teacher use)
• Vocabulary term cards and real-world examples (1 per group)
• Optional: Exit ticket (1 per student)
• Large construction or poster paper
• Optional: markers (enough for each group to decorate their poster)
When planning and preparing for this activity, consider your grouping strategy. We suggest using mixed-ability groups of no more than four students, but adjust your groups based on your students’ academic, social, and emotional needs.
Depending on your students’ needs, consider pre-teaching or reviewing vocabulary prior to engaging in this activity. Vocabulary to review: mixture, heterogeneous mixture, homogeneous mixture, solution, suspension, and colloid.
