Learning Goals & Products

Learning Goals

1

Students will be able to formulate testable questions about houseplant health and growth from careful observation of plant stress symptoms.

2

Students will be able to investigate how water, light, soil quality, and indoor climate affect beginner houseplant growth and stress over 12 weeks.

3

Students will be able to design a care routine that matches a plant health question and explains why the chosen method fits the investigation.

4

Students will be able to collect and document weekly plant data using growth measurements, soil moisture checks, before-and-after photos, and infestation observations.

5

Students will be able to analyze patterns in plant health data to compare care routines and identify anomalies or unexpected results.

6

Students will be able to justify evidence-based conclusions about which care routines best support healthy houseplant growth while distinguishing correlation from causation.

7

Students will be able to evaluate limitations in their investigation and revise plant care recommendations using feedback from peers and plant experts.

Products

12-Week Plant Investigation Notebook

A research notebook that documents each student’s plant question, method choices, weekly measurements, soil and light checks, pest observations, and personal analysis. It must show how the student revised care decisions over time and what evidence led to those changes.

team

Leaf Lab Showcase Investigation Report and Presentation

A team report and short presentation that synthesize members’ individual plant evidence into one shared investigation of houseplant care. The product must explain the method, present data visuals, address anomalies and limitations, and defend the team’s conclusions and recommendations.

Deeper Learning Competencies
Critical Thinking & Problem Solving
  • I can turn my observations of my house plant (e.g., yellowing leaves, dry soil, drooping stems) into a simple question and explain why it is relevant to plant health.
  • I can evaluate several possible questions and choose one that I can test in our 4-week school setting, then I can state a clear hypothesis and identify the independent and dependent variables I will measure.
  • I can design and adjust a testable plant-care investigation by comparing options and considering constraints (time, materials, light/water/soil access), and I can justify how my hypothesis connects to expected cause-and-effect relationships.
  • I can critique my investigation using new observations and/or peer feedback, refine my hypothesis and variables to better test the cause of stress, and explain how my evidence supports or challenges my original claim about what the plant needs.
Deeper Learning Competencies
Effective Communication
  • I can use evidence from my plant care log (photos, dated observations, and simple notes) to explain what I noticed and why I think it matters for plant health
  • I can respond to peer questions by pointing to specific observations (e.g., leaf color, soil moisture, light exposure) from my own data.
  • I can clearly communicate a testable question, hypothesis, and plan by linking my reasoning to observations from my plant and the variables I will change (light, water, or soil)
  • I can present my data story with a simple graph and explain how my results support or don’t support my hypothesis using scientific language (independent vs
  • dependent variables).
  • I can construct a claim-evidence-reasoning summary that evaluates which care change made the biggest difference and I can justify my conclusion with multiple pieces of data from my investigation
  • I can refine my explanation based on feedback by addressing gaps (missing measurements, unclear variables, or unexpected results) and updating my visuals or written reasoning.
  • I can communicate my plant-care recommendations and investigation results to an audience by connecting plant growth/stress patterns to weather or indoor climate conditions and ecosystem ideas
  • I can strengthen my argument by challenging alternative explanations, explaining limitations of my design/data, and revising my model or reasoning with clear, accurate evidence.
Deeper Learning Competencies
Content Expertise
  • I can identify and describe patterns I observe in my house plant’s daily care (light, water, soil, and growth/stress) and connect them to basic plant needs
  • I can use my observations to propose a simple question about one variable that could be tested within our classroom/time limits.
  • I can evaluate whether my plant-health question is testable and relevant by explaining what I would change (independent variable) and what I would measure/record (dependent variable)
  • I can explain a clear, evidence-based hypothesis using plant growth ideas (e.g., how light and water affect growth) and show how it fits my real observations.
  • I can refine my investigation by comparing competing explanations for stress (such as light vs
  • watering vs
  • soil/mold) and selecting the most testable approach
  • I can design a simple process with interacting care factors, describe criteria for success, and justify how I will keep other conditions as consistent as possible while tracking weather/indoor climate effects.
  • I can analyze and explain my data using a clear claim supported by my plant observations and records, interpreting relationships between variables (independent vs
  • dependent) rather than just listing results
  • I can use my findings to refine a model or explanation of plant growth in a small ecosystem, challenge alternative interpretations, and propose next-step questions or design improvements.
Deeper Learning Competencies
Self Directed Learning
  • I can use a teacher-provided checklist to plan my next steps for plant care (observations, watering, and recording baseline data) and follow the plan to collect consistent daily evidence in my care journal.
  • I can independently set a clear, testable question about plant health based on my observations (light, water, soil, or indoor climate) and choose an investigation plan that I can carry out with the materials and time available.
  • I can revise my investigation plan and care decisions using feedback and new observations, refining my hypothesis and variables (independent/dependent) so my data better answers the question about plant growth or stress.
  • I can monitor my own progress and make informed, data-based adjustments to my plant-care investigation, justifying changes in my hypothesis and method, and clearly explaining how my evidence supports what helped the plant most.
Deeper Learning Competencies
Collaboration
  • I can work with a partner to share ideas from my plant observations and help keep our plant-care journal and data table organized during daily care
  • I can listen respectfully, take turns, and follow agreed-upon roles for collecting light, water, soil, and growth information.
  • I can collaborate with my team to co-plan a testable question and simple investigation about plant health (light, water, soil, or indoor climate) and explain why it is testable within our resources
  • I can communicate my hypothesis and help decide what to measure (independent vs
  • dependent variables) while incorporating peer feedback to refine our plan.
  • I can collaborate to evaluate and improve our investigation by using observations and emerging data to adjust the hypothesis, controls, and data collection procedures
  • I can clearly describe how weather or indoor climate may affect plant growth and work with peers to resolve differences in interpretations using evidence from our logs and photos.
  • I can lead or co-lead effective collaboration by coordinating roles, timelines, and decision-making to strengthen our plant-care experiment and recommendations
  • I can actively challenge assumptions, defend our design choices with evidence, and use peer/family feedback from the House Plant Health Expo to revise how we explain interdependent effects on plant health.
