Through a teacher-led discussion, students realize that the food energy plants obtain comes from sunlight via the plant process of photosynthesis. They learn what photosynthesis is, at an age-appropriate level of detail and vocabulary, and then begin to question how we know that photosynthesis occurs, if we can't see it happening. Elodea is a common water plant that students can use to directly observe evidence of photosynthesis. When Elodea is placed in a glass beaker near a good light source, bubbles of oxygen will be released as products of photosynthesis. By counting the number of bubbles that rise to the surface in a five-minute period, students can compare the photosynthetic activity of Elodea in the presence of high and low light levels.

At the beginning of the lesson, students will view an engaging video of time-lapse photographs of flowers blooming, and students will create a T-chart listing the similarities and differences among the appearances of each flower. To formatively assess students' current knowledge of specialized plant structures, the students will sort key vocabulary words related to plants' structures into categories. Then, students will read an informational article on flowering plants and re-sort the key vocabulary words into the correct categories to demonstrate their knowledge of plants' specialized reproductive structures. Next, students will complete a lab activity in which they will carefully dissect a flower and observe the various specialized structures, collect specimens to view under the microscope and create and label scientific sketches of the flower's specialized structures. Lastly, students will design a unique flower that will have a high probability of reproductive success and provide a written response in a claim-evidence-reasoning format. This lesson results from a collaboration between the Alabama State Department of Education and ASTA.

This activity begins as a classroom investigation, but may extend to a field investigation where students will determine the effects of air temperature on seed germination. This is accomplished by developing investigative questions, recording, and analyzing data.

ELL students create and share a botanic field guide incorporating depiction, measurement, description, and classification of common Minnesota trees, shrubs, wildflowers, and plants.

This module provides descriptive notes and images that can support teaching and learning about ethnobotany and landscape ethnoecology, or the integrative study of human-resource relationships. The photos and graphics are mostly derived from field study and research at Mt. Kasigau, Kenya (1999-2015) as a case example. I openly make them available through the OER site for educational purposes. The resources attached to the module include:I. Ethnobotany- descriptive notes and images (ethnobotany_notes_oer) and a powerpoint presentation (ethno_div_oer);II. Landscape Ethnoecology- descriptive notes and images (landscape_ethnoecology_oer) and a powerpoint presentation (landscape_ethno_oer);III. Participatory Inquiry in Ethnobotany and Landscape Ethnoecology- descriptive notes and images (ethno_participatory_oer) and a powerpoint presentation (ethno_process_outcome_oer);IV.

"Exotic species are a big problem worldwide. While the mechanisms of invasion vary from one exotic species to the next, researchers can tease out patterns that are useful for understanding and ultimately managing invasion. A new study published in the Journal of Biogeography reveals how one team has applied an emerging method known as the phylogenetic field approach to do just that for exotic plants in Japan. The results offer critical insight into how ecology and evolution influence the dynamics of invasion. Darwin’s On the Origin of Species marked the first time biological invasion had been addressed using the principles of evolutionary ecology. But followed to their logical end, these principles yielded two contradictory hypotheses. The pre-adaptation hypothesis states that exotic species successfully colonize assemblages with native species that are ecologically similar because both require the same set of environmental conditions to thrive..."

Molly Reed coaches her students through an exploration of garden ecosystems. Students work in groups moving through multiple stations. Ms. Reed also gives advice on adapting this lesson to an in-classroom environment.

This activity is a field investigation where students gather information before and after learning about plants, which will allow you to compare the knowledge the previously know and have acquired through your teaching.

"Africa contains some of the most species-rich regions in the world. The tropical zone of this continent, for example, harbors the second largest extent of rain forest after the Amazon basin. However, tropical Africa is in the midst of major ecological shifts in response to human pressure and global climate change. Unfortunately, an incomplete understanding of plant diversity in this fragile region may hinder conservation efforts. In an attempt to remedy this, an international team of scientists created the RAINBIO database, a compilation of data gathered from the vast worldwide network of herbaria – or libraries of dried plant specimens. The researchers analyzed over 600,000 specimens for collecting date, geographic occurrence, and growth form (think: trees, herbs, and vines). The results provide an important perspective on plant species richness across the African tropics. For example, Cameroon, Tanzania, and the Democratic Republic of Congo are estimated to be the most species-rich countries..."

A Curriculum for Enhancing Farmer Microbial Literacy

Short Description:
The primary purpose of this course is to render the invisible world of microbes visible to farmers. This course provides scientific-based instruction exploring how microbes can assist agriculture. Although the course is designed for farmers, this material can also help extension agents, curious citizen scientists, and other non-experts interested in enhancing their microbial literacy.

Long Description:
The invisibility, complexity, and general opaqueness of soil microbial life makes learning about the “black box of soil” difficult. To address this challenge, my project-based biology senior thesis endeavors to develop a biology-based curriculum for farmers to increase microbial literacy. A transition to a microbially centric agriculture necessitates the development of a new knowledge infrastructure. My senior thesis project aspires to contribute to this new, necessary, and expanding infrastructure. It is critical that farmers recognize their unique role as stewards of not only plants and animals but also as shepherds of an unfathomably complex, necessary, and wondrous herd of microbes.

In this lesson, students investigate photosynthesis through hands-on experiments, videos, and discussion of text. They work in small groups with picture cards to create a chart showing how plants transform carbon dioxide, water, and light energy into carbohydrates and oxygen. After working collaboratively, students will create their own diagrams of photosynthesis. Because plant observations must occur over time, this lesson will take several days to complete. This lesson results from a collaboration between the Alabama State Department of Education and ASTA.
