This Google Folder leads to an online module that is designed for students to learn concepts of evolution, descent with modification, natural selection, and more. There is both a student guide and a teacher's guide to help navigate through the module. Google forms are also available to support learning throughout the module. Interactive activities and simulations are also included for students to enjoy and learn from. 

In common experience, the term "adapting" usually refers to changes during an organism's lifetime. In contrast, evolutionary biologists use the term "adaptation" to refer to a heritable trait that increases fitness. To help students reconcile these different concepts, this activity introduces the concept of phenotypic plasticity (the ability of an organism to adapt to different environments within its lifetime). Questions guide students in analyzing how the balance between the advantages and disadvantages of a characteristic (e.g. an animal's color) can vary in different circumstances, how phenotypic plasticity can be a heritable trait that can optimize fitness in a variable environment, and how natural selection can influence the amount of phenotypic plasticity in a population. This activity is designed to help high school students meet the Next Generation Science Standards and the Common Core State Standards.

This Immersion Unit provides a coherent series of lessons designed to guide students in developing deep conceptual understanding that is aligned with the standards, key science concepts, and essential features of classroom inquiry (as defined by the National Science Education Standards).  Unit Overarching Concepts Populations of living organisms change or stay the same over time as a result of the interactions between the genetic variations that are expressed by the individuals in the populations and the environment in which the population lives. Science knowledge advances through inquiry. Unit Supporting Concepts Individual organisms with certain variations of traits (adaptations) are more likely than others to survive and reproduce successfully.When environmental conditions change it can affect the survival of both individual organisms and entire species. Natural selection determines the differential survival of groups of organisms. A small advantage in escaping a predator, resisting a drug, etc. can lead to the spread of a trait in a modest number of generations. Mutations are a source of variation in an individual’s genotype, and it can result in a change in phenotype––good or bad. Scientific progress is made by asking meaningful questions and conducting careful investigations, using appropriate tools and technology to perform tests, collect data, analyze relationships, and display data. No matter how well one scientific explanation fits observations, a new explanation might fit them just as well or better, or might fit a wider range of observations. In science, the testing, revising, and occasional discarding of explanations, new and old, never ends. This unit was developed through the large Math and Science Partnership project called System-wide Change for All Learners and Educators (SCALE), involving a collaboration among Los Angeles School District educators, California State University science and education faculty, and UW-Madison SCALE staff.

This fill-in-the-blank timeline is a planning tool for teachers to use when figuring out when to begin the steps associated with conducting a two-generation artificial selection experiment using Fast Plants. Teachers preparing for any selection experiment will find this timeline helpful, including those planning for the AP Biology Lab 1 of Big Idea 1: Evolution, Artificial Selection.

After studying the basics of enzyme function, students will be exposed to the history and evolution of lactose intolerance/lactase persistence. Both whole group and individual activities will ask students to interact with the concept. They will conduct a lab to understand the role of enzymes in lactose digestion and communicate their knowledge by creating a public health poster.

This lesson plan, from the University of Wisconsin-Madisons Wisconsin Fast Plants, is for a high school biology investigation into evolution and artificial selection while using Fast Plants polycot seeds. The lesson plan describes student science performance for in-classroom learning as well as distance learning, and assessment for student learning. Additionally, this resource includes a sample calendar to demonstrate how educators can implement this investigation into their classroom. This resource is related to Evidence of Natural Selection Activities and Investigating Selection with New Polycots Fast Plants, which are available to view separately.

It is well known that mutation is the ultimate source of variation. Without adequate variation, plant breeding is impossible. To start a breeding program, the breeder must find the appropriate genotype (containing the desired genes) from existing variation, or create the variation if it is not found in nature. Mutagenesis is the process by which new alleles are created. The purpose of this chapter is to discuss mutagenesis as both a technique and a breeding method. The newly created mutants may be used as parents in future breeding programs, in which case mutagenesis is a breeding technique as a source of variation. However, an induced mutant can be systematically processed through conventional breeding steps to be released as a cultivar, hence making it a breeding method (mutation breeding). Mutations arise spontaneously in nature and are pivotal in natural evolution.

In this curriculum module, students in high school life science, marine science, and/or chemistry courses act as interdisciplinary scientists and delegates to investigate how the changing carbon cycle will affect the oceans along with their integral populations.

The oceans cover 70 percent of the planet and play a critical role in regulating atmospheric carbon dioxide through the interaction of physical, chemical, and biological processes. As a result of anthropogenic activity, a doubling of the atmospheric CO2 concentration (to 760 ppm) is expected to occur by the end of this century. A quarter of the total CO2 emitted has already been absorbed by the surface oceans, changing the marine carbonate system, resulting in a decrease in pH, a change in carbonate-ion concentrations, and a change in the speciation of macro and micronutrients. The shift in the carbonate system is already drastically affecting biological processes in the oceans and is predicted to have major consequences on carbon export to the deep ocean with reverberating effects on atmospheric CO2. Put in simple terms, ocean acidification is a complex phenomenon with complex consequences. Understanding complexity and the impact of ocean acidification requires systems thinking – both in research and in education. Scientific advancement will help us better understand the problem and devise more effective solutions, but executing these solutions will require widespread public participation to mitigate this global problem.

Through these lessons, students closely model what is occurring in laboratories worldwide and at Institute for Systems Biology (ISB) through Monica Orellana’s research to analyze the effect CO2 has on ocean chemistry, ecosystems and human societies. Students experiment, analyze public data, and prepare for a mock summit to address concerns. Student groups represent key “interest groups” and design two experiments to observe the effects of CO2 on seawater pH, diatom growth, algal blooms, nutrient availability, and/or shell dissolution.

Take a breath — where does the oxygen you inhaled come from? In our changing world, will we always have enough oxygen? What is in water that supports life? What is known? How do we know what we know about our vast oceans? These are just a few of the driving questions explored in this interactive STEAM high school curriculum module.

Students in marine science, environmental science, physics, chemistry, biology, integrated science, biotechnology and/or STEAM courses can use this curriculum module in order to use real-world, big data to investigate how our “invisible forest” influences ocean and Earth systems. Students build an art project to represent their new understanding and share this with the broader community.

This 4-week set of lessons is based on the oceanographic research of Dr. Anne Thompson of Portland State University in Oregon, which focuses on the abundant ocean phytoplankton Prochlorococcus. These interdisciplinary STEAM lessons were inspired by Dr. Thompson’s lab and fieldwork as well as many beautiful visualizations of Prochlorococcus, the ocean, and Earth. Students learn about the impact and importance of Prochlorococcus as the smallest and most abundant photosynthetic organism on our planet. Through the lessons, students act as both scientists and artists as they explore where breathable oxygen comes from and consider how to communicate the importance of tiny cells to human survival.

This module is written as a phenomenon-based, Next Generation Science Standards (NGSS) three-dimensional learning unit. Each of the lessons below also has an integrated, optional Project-Based Learning component that guides students as they complete the PBL process. Students learn to model a system and also design and evaluate questions to investigate phenomena. Students ultimately learn what is in a drop of ocean water and showcase how their drop contributes to our health and the stability and dynamics of global systems.
