The Biggest Mystery of All(aka our goal)
Students often ignore plants - how do we make plants exciting & memorable?
Our Mystery Case File Connections
Writing emphasis
Plant evolution
Form & Function
Human connections
Case File 1Evolution and Plant Diversity
Plant evolutionary relationships
Phylogenetics
Morphological and physiological adaptations of plants to the terrestrial environment
Alternation of generations
Diverse types of science Writing
Plant Evolution: Hands on Quantitative Lab
Students will build and interpret phylogenetic trees based on plant traits

Plant Diversity: Writing
Choose a plant (or a few plants) from visiting the greenhouse
Outside Research
Place the plant in evolutionary and ecological context
Assessment: develop signage/exhibits for the university greenhouse and website
Case File 2: Heavy Metals and Phytoremediation
Case Learning Goals
• Identify macronutrients and micronutrients in plants and their uptake and movement
• Describe the terms tolerance and toxicity as it relates to plants nutrients
• List and describe several metals and their reported levels in typical polluted and non-polluted soils.
• Assess the suitability of an identified site for phytoremediation
• Describe and present a poster with a detailed phytoremediation strategy for your identified site
Extension to Higher Levels
Writing and Assessment
Activities
Background Knowledge
1. Identify macronutrients and micronutrients and their movement in plants
2. Discuss tolerance and toxicity as they relate to plant nutrients
3. Heavy metals and their reported levels in typical polluted and non-polluted soils.
4. Scenarios are presented (case study)
5. Develop phytoremediation plan

interactions
Why are these wild
sunflowers so small?
Why do I see more pest damage on
sunflowers on my farm?
