Students investigate, “How can we grow crystals and explain what controls their size, shape, and growth rate?” Teams conduct short research and multiple controlled trials, using measurement tools, observation notes, and photos to track how environmental conditions affect crystal growth while distinguishing this process from organism growth and genetic influences. They communicate evidence through a labeled before-and-after display with photos, measurements, and observations from each trial, then create a final reflection poster explaining changes in their understanding of crystal size, shape, growth rate, and collaboration.

Students will investigate, “How can we grow crystals and explain what controls their size, shape, and growth rate?” Using several credible sources and multiple trials, they will measure and document crystal growth with tools, observation notes, and photos, then use evidence to explain how environmental conditions affect growth. Students will distinguish nonliving crystal growth from organism growth and compare how environmental and genetic factors influence organisms. Teams will share decisions, analyze results, and create a labeled before-and-after display and reflection poster showing changes in their scientific understanding and collaboration.

Teams will create a shared investigation plan that asks, “How can we grow crystals and explain what controls their size, shape, and growth rate?” Throughout multiple trials, students will maintain a growth record with tool-based measurements, observation notes, photos, and research-based questions about changing conditions. Each team will produce a labeled before-and-after crystal growth display comparing photos, measurements, observations, size, shape, and growth rate across trials, while distinguishing crystal formation from organism growth influenced by environmental and genetic factors. Each student will also create a final reflection poster explaining how the evidence changed their understanding of crystal growth and how collaboration, feedback, and shared decisions shaped the investigation.

Begin with a mystery gallery of teacher-prepared crystals, crystal-growth time-lapse images, and growing plants, asking teams to measure, photograph, and record observations without handling unknown substances. Introduce the essential question, “How can we grow crystals and explain what controls their size, shape, and growth rate?” Teams compare crystal formation with organism growth, identify environmental influences, and develop a focused research question for multiple trials using several reliable sources. Students assign collaborative roles and sketch plans for a labeled before-and-after display, then preview the final reflection poster about changes in their understanding and collaboration.

Host a Crystal Growth Gallery Walk where teams exhibit labeled before-and-after displays with photos, measurements, and observation notes from each trial. Students explain how their evidence answers, “How can we grow crystals and explain what controls their size, shape, and growth rate?” and distinguish crystal formation from organism growth influenced by environmental and genetic factors. Visitors ask questions and leave feedback, while each team shares a reflection poster showing how the experiment changed its understanding of crystal growth and collaboration.
