Energy Storage in Plants: Should Biofuels Be Made from Seeds or Leaves and Stems?
The investigation involves students determining where plants store potential energy (a.k.a., chemical energy). In the investigation, students will grow rapid cycling Brassica rapa plants and observe that the dry weight (mass) increases because of photosynthesis. They will measure the amount of energy stored in seeds and vegetative tissues by using a simple calorimeter. The information collected...

Writing an Ecological Research Proposal
This is a writing assignment that is broken up into steps that emulate the process of developing a novel scientific question and creating a research proposal to answer the question. The assignment is loosely based on the NSF Graduate Research Fellowship Program proposal and consists of all of the same pieces except for Broader Impacts. This assignment was developed for a course in plant ecology,...

Why are some plants hairy?
These slides contain information about plant hairs called trichomes. The slides can be used to demonstrate plant structural adaptions to biotic and abiotic conditions. Slides which feature confocal/fluorescence microscopy may be useful as examples in a cell biology class.

A Structured Inquiry Approach to Cotyledon Phenotyping
Transmission genetics labs are valuable for undergraduate development of analytical thinking skills. However, these labs typically present the scientific process as artificially linear, with a single "right answer." This resource describes an inquiry-based approach to teaching a transmission genetics lab focused on plant cotyledon color. Student groups are required to develop a hypothesis based...
