Plant structures and life processes become evidence-based learning in this Grade 7 Science learning stations activity for Alberta's Plants for Food and Fibre topic. Students examine classic investigations and use observations to explain how roots, stems, leaves and flowers contribute to the processes plants need for survival.

Investigate Plant Structures Through Evidence

Rather than studying plant parts only as isolated vocabulary, students connect structures with water movement, gas exchange and photosynthesis. The station format asks learners to gather information from real investigations, record evidence and then bring ideas together in a station wrap-up.

Students work with important Grade 7 plant science concepts including:

• Functions of roots, stems, leaves and flowers
• Connections between plant structures and water movement
• Gas exchange as part of plant life processes
• The relationship between plant structures and photosynthesis
• Comparing evidence from different investigations
• Explaining how multiple plant structures work together

What Teachers Receive

• Station cards built around classic plant investigations
• A student station recording sheet for collecting evidence
• A station wrap-up for comparing and connecting findings
• A teacher guide included in the Answer Key PDF

The teacher guide adds practical support with learning objectives, teaching tips, discussion questions and common mistakes. These components make it easier to introduce the activity, guide student conversations and address misunderstandings that arise while students interpret evidence.

Use It as a Classroom Investigation

Place the station cards around the room and have students rotate through them while completing their recording sheet. After the rotations, use the wrap-up to move from individual observations to a broader explanation of plant function. The activity can support a Plants for Food and Fibre lesson, evidence-based science discussion, collaborative station rotation or review of plant structures and processes.

The value of this activity comes from the connection between structure, process and evidence. Students are not simply identifying a root, stem, leaf or flower. They use observations from investigations to explain what those structures do and compare findings to build a more connected picture of how plants function.

Designed for Grade 7 Science within an Alberta framework, this learning stations resource keeps the focus on plant structures, water movement, gas exchange, photosynthesis and evidence-based explanation.
