Living Plants Today

Overview

Students explore how plants are living things by observing their needs and how they grow. Students also learn that Indigenous peoples use plants in respectful, practical ways, connecting science observations with cultural knowledge.

Learning intentions

• Students will describe how plants are living things that need water, light, air, and space to grow.
• Students will compare how different plants grow in different conditions.
• Students will use observations to explain why plants are important in our environment.
• Students will identify examples of how Indigenous cultures use plants respectfully.

Success criteria

• I can name the basic needs of plants and explain how they help plants grow.
• I can make careful observations and record what I notice about plant growth.
• I can use evidence from my investigation to answer questions about plant needs.
• I can describe at least one respectful cultural use of plants and explain why it matters.

Curriculum links

• Living things and their basic needs: understanding that plants require specific conditions to live and grow.
• Growth and changes in plants: using observations to describe how plants develop over time.
• Plants in the environment: investigating relationships between plants and their surroundings.
• Connections to Indigenous perspectives: recognizing that Indigenous peoples have knowledge and uses for local plants.

Lesson structure (40 minutes)

1. 3 min – Hook & question: Show 2–3 quick plant images (or real plants) that look healthy and one that looks wilted. Ask: “What do you think plants need to stay healthy?”
2. 7 min – Mini lesson: plant needs: Teach the idea that plants are living things. Focus on water, light, air (for breathing/respiration), and space (room to grow). Clarify that plants can survive for a short time without one factor, but growth and health change when needs aren’t met.
3. 8 min – Cultural connections talk: Share a short, age-appropriate discussion about respectful plant knowledge in Indigenous cultures (for example: medicinal uses, food uses, weaving/basket materials, or plant care practices). Emphasize respect, place-based knowledge, and that plants are part of community life. Keep it general and classroom-safe (no sacred or restricted details).
4. 10 min – Investigation setup (stations): In small groups, students look at a “plant needs” setup with three simple conditions using classroom-safe plants (e.g., seedlings or fast-growing plants):

• Group A: plants with light and water
• Group B: plants with water but limited light (covered box or dark corner)
• Group C: plants with light but limited water (small amount of water removed) Students do not need to wait for long-term results today; they make predictions and observe initial differences (seed/soil condition, moisture level, light exposure).

5. 7 min – Predict & record: Students complete a brief observation/prediction chart:

• “We predict the plant will… because…”
• “Today we notice…” Circulate to check for accurate language: “needs,” “growing,” “healthy,” “light,” “water,” “air.”

6. 4 min – Share-out & evidence: Each group shares one prediction and one observation. Prompt with: “What evidence from today helps you make your prediction?” Reinforce that fair tests change only one factor at a time.
7. 1 min – Exit ticket: Students answer: “One way plants help our environment is…” and “One plant need is…”

Resources

• 2–3 real plants or clear plant photos (healthy and wilted)
• Simple station materials:
• Small pots or clear cups with soil
• Seeds/seedlings (fast-growing if possible)
• Watering cups/spray bottles
• Cardboard boxes or paper for limiting light
• Observation/prediction chart sheets (one per student or per group)
• Pencils, crayons, or markers
• Labels/signage for each condition (Light + Water, Water only, Light only)
• Timer for station rotation (if needed)
• Teacher-prepared example of respectful Indigenous plant knowledge (short script or notes)

Assessment

• Observation of group discussions during predictions and “share-out” for correct use of plant-need vocabulary.
• Collected prediction/observation charts to check understanding of plant needs and evidence-based reasoning.
• Exit ticket responses to assess whether students can explain a plant need and a plant’s environmental importance.

Differentiation

• Support:
• Provide sentence starters: “I predict… because…”, “Today I notice…”, “Plants need… so…”
• Offer a word bank for water, light, air, space, grow, healthy, environment.
• Extension:
• Ask advanced students to propose a fair test question (e.g., “What happens if we change only light?”) and explain why only one change matters.
• EAL learners:
• Use visuals at stations and model key sentence frames aloud before group work.
• Allow oral responses for the exit ticket if needed.
• SEN:
• Reduce writing by using “circle or draw” supports on the chart (e.g., draw a plant with sun/water icons).
• Assign clear roles in groups (materials manager, observer, recorder, reporter).
