Tree Identification Discussion Questions for Grade 11 Science
Question 1: What are the key characteristics used in tree identification?
- Leaf Structure
- Types of leaves (broadleaf vs. needle-like)
- Leaf arrangement (opposite, alternate, whorled)
- Leaf shape (lobed, serrated, entire)
- Bark Texture and Color
- Differences in bark texture (smooth, rough, scaly)
- Color variations and what they signify
- Tree Form and Growth Habit
- Overall shape (pyramidal, spreading, columnar)
- Growth patterns and adaptations to the environment
Question 2: How do seasonal changes affect tree identification?
- Leaf Phenology
- Changes in leaf color and fall
- Winter characteristics (bare branches, buds)
- Flowers and Fruits
- Timing of flowering and fruiting
- Importance of reproductive structures in identification
- Impact of Climate
- How climate change might alter growth patterns
- Effects of local weather on tree characteristics throughout the seasons
Question 3: What is the significance of native vs. non-native tree species?
- Definition of Native and Non-Native Species
- Characteristics and examples of native tree species
- Differences and examples of non-native tree species
- Ecological Impact
- The role of native trees in local ecosystems
- Consequences of introducing non-native species (biodiversity loss, disease)
- Cultural Significance
