The Fishy Mixture Water Quality Inquiry Lab is an inquiry project including multiple lessons taught over the span of 1 to 2 weeks. To help manage the magnitude of this project, you will find the project split into 4 parts.
The purpose for the EVALUATION stage is for both students and teachers to determine how much learning and understanding has taken place. To accomplish this goal, we complete several activities:
1) We evaluate the water samples using the Fishy Mixture Water Quality Rubric (Water Quality Scoring Rubric Example). I often bring the samples up to the front and we evaluate the samples together as a way of sharing our data. During this time, we share what separation methods were successful and which were not. This video explains the evaluation of the water samples:
2) Students plan and write a RECALL Lab Conclusion (see these related lessons: Writing a RECALL Lab Conclusion Part 1 and Part 2) using the graphic organizer in the Fishy Mixture Lab Sheet. I often give students a choice about how they want to present this information: finalize their planning into a final lab report or finalize their planning into a final creative presentation (Prezi, Google slideshow, Infographic, Google poster). For examples of student RECALL Lab Conclusions, view these: Fishy Mixture RECALL Student Example 1, Fishy Mixture RECALL Student Example 2 and Fishy Mixture RECALL Planning Student Example. For writing rubrics, try: Scientific Communication Rubric or Argument from Evidence Rubric.
3) Upon completion of this project, a final class discussion using several prompts to assess what we have learned and think about next steps is an appropriate closing activity. These prompts may include:
- What can you conclude about separating mixtures from this activity?
- What do you think we should do to save the white sucker fish?
- What other types of mixtures might be harmful to humans or the environment?
- Whose responsibility is it to provide us with safe water?
