  1. Ch-Ch-Ch-ChiaSeeds for Inquiry (as seen in NSTA Science Scope, April/May 2011)

  2. Engage • Create a “mini-pet” by sprouting seeds on a paper towel in a humid growing chamber. • Students first draw a design on the paper towel with markers, and then moisten the towel before sprinkling the seeds on their drawings. • Carefully insert the “mini-pet” inside a plastic zip-top bag (the growing chamber). • Place “mini-pets” in various locations around the classroom, and watch as the seeds sprout.

  3. Explore • Students compare their sprouted mini-pets and observe differences. • Seed germination • Sprout growth • Leaf color • Root length • As they note variations they speculate on possible causes. • These discussions lead to the generation of inferences.

  4. Inferences generated by students through experience with chia mini-pets

  5. Question Generating Stems Why does ….? How does ….? What if ….? What could be the reason for ….? What would happen if ….? How does _____ respond to ____? How does _____ compare to ____? Does _____ when _____? How could we find out if _____? O/I/H exit ticket

  6. Explain (teacher-led) • Choose one of the inferences to demonstrate how to devise a simple, repeatable experimental test. • Sample procedures follow; however, students should devise their own procedures for testing their hypothesis.

  7. Extend/Elaborate • Each group of students selects an inference and designs an experiment for testing it. • Experiments are conducted and repeated, as needed, over a two-week period. Chia Investigation Plan Chia Investigation Worksheet

  8. Evaluate There are several places for formative assessment during this inquiry investigation: • The Engage offers a chance to assess plant growing experience. • The Explore offers a chance to assess vocabulary terms. • The Explore also offers a chance to assess hypothesis generation. • The Extend/Elaborate offers a chance to assess experimental design.

  9. Other Evaluate ideas … (besides science journal entries) • Observation/Inference/Hypothesis exit ticket • Investigation worksheet • Investigation Plan • Student self-grading sheet • Inquiry rubric • RERUN paragraph • “Share-out”

  10. Chia Seed RERUN Recall: Summarize what you did in the investigation. Explain: Explain the purpose of the investigation. Results: Describe the results of the investigation and what they mean. Uncertainties: Describe what you are still unsure about. New: Write at least two new things that you learned from this investigation.
