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

Morphology

Reproduction

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
