Leaf functions in Grade 6 science become concrete through five Alberta forest cases that connect photosynthesis, gas exchange, and transpiration to real changes in trees and forests. Students examine how leaf and needle function responds to environmental challenges and use each case to connect plant processes with growth, water use, and recovery.

Explore Leaf Function Through Alberta Forest Cases

This learning stations activity focuses on leaves and needles as working structures in trees. Students explain how they support photosynthesis, gas exchange, and transpiration, then compare what happens when drought, insects, or wildfire disrupt those functions. The Alberta forest context keeps the science connected to the Trees and Forests topic rather than treating plant processes as isolated vocabulary.

As groups rotate through the station cards, they record key information on their own station recording sheet. The cases ask students to consider how environmental disturbances affect leaves and needles and what those changes can mean for tree growth, water use, and recovery.

What Students Practice

• Explaining the roles of leaves and needles in photosynthesis, gas exchange, and transpiration
• Comparing the effects of drought, insects, and wildfire on leaf function
• Relating leaf traits and leaf loss to tree growth
• Connecting changes in leaves with water use and forest recovery
• Synthesizing ideas from the station cases in a station wrap-up

What You Receive

• ✔️ Station cards built around Alberta forest cases
• ✔️ Student station recording sheet for collecting information during rotations
• ✔️ Station wrap-up for bringing ideas together after the activity
• ✔️ Teacher guide included in the Answer Key PDF
• ✔️ Learning objectives, teaching tips, discussion questions, and common mistakes in the teacher guide

Built for Classroom Rotation

Place one case-study card at each station and have small groups rotate through the room, recording their observations and ideas on the student sheet. After the rotations, use the wrap-up to consolidate the science and the teacher guide discussion questions to compare cases as a class.

This structure makes the resource useful for an Alberta Grade 6 Trees and Forests lesson, collaborative science practice, or a focused review of plant functions and forest responses. Instead of stopping at definitions, students apply leaf-function concepts across different forest situations and connect changes at the leaf level to larger effects on trees.
