A module guiding students through the process of building a biodiversity dataset using field data and protocols derived for a study of the invasive aquatic plant species, European frog-bit (Hydrocharis morsus-ranae L.). 

A novel activity was designed to introduce students to the concepts of natural selection and life history using an active-learning, constructivist format. It consisted of two parts: 1) a brief introduction to the basic mechanism of natural selection, and 2) a game that introduces life-history strategies. The activity was designed for use in the college classroom. It was shown to be an effective means of fostering a deep and transferrable conceptual understanding of the principles of natural selection specifically through the lens of life-history strategies. The activity is available in the supporting materials. It takes approximately one 50-minute period to complete.

Students generate predictions and test three hypotheses about how biodiversity is affected by urbanization over time using citizen science generated bird count data and land use data from 13 locations in Florida over a 10 year time span

Targeting undergraduate students in lower-division ecology courses, this module guides students through authentic research. The purpose of this project is to provide hands-on research experience to enhance students' skills and confidence in the field of ecology. Within the module, students conduct a research project that allows them to: (1) explore recent studies in urban ecology, introducing the ecological research tools of camera traps and citizen science; (2) gain experience as a citizen scientist, generating data for different projects in Zooniverse; (3) write a hypothesis based on two possible research questions; and (4) analyze and test their hypothesis. The two possible research questions are: How do species’ diel activity patterns differ between land cover types (e.g., forest vs. anthropogenic)? How do diel activity patterns differ between/among species? Data for analysis is obtained through Snapshot USA. Through the module, students obtain skills in constructively reading and evaluating research papers, constructing testable hypotheses and predictions, using Excel to calculate Chi-Square and P-Values, interpreting statistical evidence, and presenting research findings.

Students will navigate through different stations experiencing simulations of adaptations, manipulations of 3D examples, and making connections to the standards to formulate hypotheses about certain adaptations and how they manifest in the morphology.

In this lesson students 1) become familiar with various graphs that are used to study diversity patterns within and across sites, 2) learn about some of the questions that can be addressed by metabarcoding studies, and 3) reflect on an interview with evolutionary ecologist Maria Rebolleda Gomez, who collected the data used in the lesson.

Traditional Ecological Knowledge is based on deep understanding of systems from observations made over hundreds to thousands of years. This resource connects Traditional Ecological Knowledge to modern conservation through media and primary literature interpretation. The adaptation of this research aims to link the material to the ecological concept of the intermediate disturbance hypothesis and to highlight ecologists whose careers have focused on the concept.

Stream reach metabolism integrates organism respiration & production to provide a valuable ecosystem measure that varies as a function of biotic & abiotic factors. As a powerful indicator of whole system functioning, it is important students can estimate stream metabolism. This field lesson engages students in study of ecosystem metabolism through its components, production & respiration. Students connect to the reach through guided reflection, predict and explore dissolved oxygen, investigate metabolism drivers in a matching game of diel oxygen curves from streams around the world, and collect & analyze diel dissolved oxygen data. This is designed for mid to upper-level undergraduates to complete in one 2-hour field visit at a wadable reach of run habitat, and a 30-minute analysis session. This lesson complements lessons including hydrogeomorphology, field sketching, organismal studies, ecosystem energetics, mapping, any that provide an ecosystem or energetic framework (RCC, Fluvial Landscape Ecology) to student understanding of flowing waters. Additionally, it can be replicated in space and time to highlight the relative importance of the key drivers of ecosystem metabolism.

Scientists have discovered that microplastic pollution is ubiquitous in the environment, but the small size of these microscopic pollutants prohibits most people from recognizing their prevalence. This river-based field lesson will introduce environmental science students to this emerging environmental concern, and encourages them to explore microplastics in their local waterways with sample collection, density separation and field-based microscopy. Students will appreciate the opportunity to connect to this topic from anywhere in the world, allowing them to see microplastics with their own eyes and without the use of sophisticated equipment. In addition, this lesson helps students recognize their own personal impact on microplastic pollution and identify ways to reduce their creation of microplastics.

A lecture will be hosted by the educator. The first four sections cover factual information and in the activity students will draw conclusions about spore germination. The last section will highlight a scientist and current trends in mycology.

Environmental health is a field of study within public health that is concerned with human-environment interactions, and specifically, how the environment influences public well-being. In this module, students will explore how environmental pollution impacts public health through comparing cancer rates of areas with known environmental pollutants to the national average through a t-test. Students can further their knowledge by comparing the concentrations of atmospheric pollutants in areas with known sources to control sites without such sources. Project EDDIE modules are designed with an A-B-C structure to make them flexible and adaptable to a range of student levels and course structures.

A foundational knowledge of the relationship between structure and function is critical to understanding how enzymes work. The seemingly invisible nature of these molecular interactions makes it challenging for undergraduate students to conceptualize the dynamic changes that occur during a catalytic cycle. In this Lesson, we describe an interactive, collaborative modeling activity that we use in introductory biology courses to teach students how enzymes catalyze chemical reactions. First, the students imagine a fictitious enzyme and its associated reaction, and use modeling compound to demonstrate the progression of the reaction while focusing on the three-dimensional shape of active site and substrate in facilitating this catalysis. Second, they then select one of four types of enzymatic regulation (competitive inhibition, allosteric inhibition, allosteric activation, or feedback inhibitions) to incorporate into their model. They then demonstrate these reactions to groups of peers. This student-centered approach uses active learning and peer instruction to provide students with prompt feedback to strengthen their understanding of the inter-relatedness of structure and function. This modeling activity concludes with student reflection and discussion, and student learning is assessed with exam questions.

Teaching scientific literacy skills can help combat the propagation of misinformation online. This lesson is intended to give students practice identifying reliable scientific information on the Internet, in the context of vaccine safety. It was designed for a first-year seminar taught fully through remote instruction but can be adapted for any in-person or blended course. It can also be easily modified to use for other biologically-relevant topics and is especially well suited for controversial topics. This lesson consists of three activities. First, students review an article about identifying reliable Internet resources and search online for vaccine safety information. Then, students meet in small groups to review and rank the resources that each of them found from most to least reliable, referencing the criteria laid out by the CRAAP test (Currency, Relevance, Accuracy, Authority, Purpose). After ranking each resource, students reflect on how their thinking about online resources has changed during the activity and how they will evaluate scientific information online in the future. Finally, students use the reliable resources that they and their classmates compiled during the activity as references to write about how the biology of vaccines relates to the five Core Concepts. Following this lesson, 100% of student groups were able to correctly identify at least one reliable and unreliable online resource and 95% of groups were able to articulate particular qualities of resources that helped them establish their reliability. Further, 100% of groups could articulate how their thinking had changed throughout this activity.

As the basic unit of life, cells are a foundational concept for all of biology. Before students can appreciate how eukaryotic cells function either in isolation or in higher order and multicellular organisms, they must first have a basic understanding of the organelles that make up these cells. The primary objective of this lesson is to provide a fun and engaging way for students to learn the function and arrangement of eukaryotic organelles. This lesson uses familiar and easy to learn games, such as Pictionary® and Bingo, to help students enrolled in introductory, non-majors biology courses better recognize cellular organelles and understand their functions.

University capstone projects can offer science students a rich research experience that illustrates the process of doing scientific research, and can also help students better choose future academic and career pathways. While capstone projects are an effective component of students' learning in the sciences, they are resource and labor intensive for supervising faculty and are not always logistically feasible in understaffed and/or under-resourced departments and colleges. A good compromise is to incorporate a significant research component into upper division classes. This article documents a project I have incorporated into a plant ecology course that I teach every spring. This project gives students a taste of what practicing ecologists do in their professional lives. Students learn how to survey vegetation and environmental factors in the field, apply several statistical analysis techniques, formulate testable hypotheses relevant to a local plant community, analyze a large shared data set, and communicate their findings both in writing and in a public presentation. Over the weeks required for this project, students learn that doing science is quite different from how they typically learn about science. Most say that, while this project is one of the hardest they have completed in their time in university, they appreciate being treated like a fellow scientist rather than as "just a student." Additionally, students' findings often reveal complex and subtle interactions in the plant community sampled, providing further insight to and examples of emergent properties of biological communities.

A successful scientist combines skill, creativity, and the art of persuasion to excel in his or her field of study. Critically important for the professional scientist is the ability to not only conduct research, but also to conceive a project and obtain funding to support research goals. As students grow in their scientific process skills over the course of their training, they are often surprised by the structures and processes used by professional scientists to procure funds for their work. We describe a semester-long experience in which students engage the process of science to design an innovative research plan on a topic that is relevant to the scientific community and society. Research teams seek funding to pursue a novel, high-impact research question, and submit proposals for peer review in a mock NSF-style study section. The module design uses a scaffolded series of writing and peer review activities, and culminates in a Pecha Kucha event in which students orally pitch and defend their proposal and vote for the best in session. The module may be scaled and adapted to suit a wide range of contexts where proposal writing and peer review is emphasized.

To prepare biology undergraduates to be able to read and evaluate the primary literature, it is beneficial to teach students how to write documents in the style of professional science style manuscripts. By breaking manuscripts into individual section assignments, we can distribute instruction across a four-year undergraduate curriculum to scaffold writing practice mastery. These skills are aided by peer review, writing tutor instruction, and assignment repetition. Students gain not only competency in writing about the discipline, but can better understand and critically evaluate the written work of others. The science writing and communication skills gathered over the course of this curricular framework provide all students with expertise in accessing science themselves and disseminating science to others.

Reading primary scientific literature enhances students’ understanding of material, increases their self-efficacy, and critical thinking skills. However, scientific articles often present multiple challenges to the students, the first among them is the unfamiliar nature of scientific texts: their high information density, formal language, and abundance of scientific jargon. In this lesson, students are taught the Talking to the Text method to metacognitively read scientific texts. The Talking to the Text method, which is part of the Reading Apprenticeship approach, enables students to have a metacognitive conversation with a scientific text, annotating it with their own questions, connections to previous knowledge, predictions, and drawings. The method is introduced through instructor’s modeling, individual practice, peer interactions, and class discussions. The collaborative approach of this lesson normalizes the struggles that students face when reading complex scientific texts. We have successfully used the Talking to the Text method in an introductory biology course with diverse students who often do not have experience in reading dense scientific texts. We find that this method promotes inclusion and holds students accountable to address what they do not understand in the text. In a survey, half of the students indicated that they were still using the method at the end of the semester. Students commented that the method improved their understanding of concepts, built their metacognitive skills, and helped them connect new information with what they already know. We believe that this method can be valuable for all students who are starting to read complex scientific texts.
