Physical and Chemical Changes Choice Board for Grade 5
By Kristina H.
A choice board for 5th grade advanced learners that explores physical and chemical changes through engineering-style projects, where students pick one activity or a series of three. It builds understanding of key terms, applied science reasoning, and design-test-improve thinking, with real-world contexts like rust, food heating, and water purification to anchor the ideas.

Teacher Guide & Tips
- Introduce the Key Terms (physical change, chemical change, engineering design) as a whole-class warm-up before students choose a project, so everyone shares a common vocabulary.
- Discussion question: Why is rust a chemical change while melting ice is a physical change, even though both involve temperature? What evidence would tell you which kind of change happened?
- Scaffold for students who need support: provide a simple two-column chart (physical vs. chemical) and sentence starters like "This change is ___ because the substance ___."
- Extension for advanced students: challenge them to design a test that distinguishes a physical from a chemical change in an unfamiliar material, then explain their reasoning in writing.
- Estimated time: about 45 minutes for a single project or the vocabulary introduction, with longer blocks needed if students complete a series of three projects.
