After the summer nesting period, broad winged hawks are known for migrating nearly 10,000 kilometers, (6,200 miles) each fall from their breeding grounds in North America to tropical biomes in South America, where they spend the winter. The International Union for Conservation of Nature has labeled broad-winged hawks as a species of "least…

This article provides two activities, exploring genetic drift of small breeding populations, highlighting the black-footed ferret ("Mustela nigripes"). According to the U.S. Fish and Wildlife service, all black-footed ferrets are descended from 18 individuals, making them extremely vulnerable to genetic drift. They were thought to be…

In the 1990s, classes throughout the United States began participating in Classroom FeederWatch, sending data on birds they had seen at feeders in their schoolyards to the Cornell Lab of Ornithology. The launch of eBird in 2002 opened up new possibilities for submitting data on all types of bird species, allowing users to record and upload…

Ocean acidification (OA) has been called climate change's evil twin for a reason. Increased levels of carbon dioxide, caused by humans burning fossil fuels, are not only causing a rise in global temperature but are also having adverse impacts on marine ecosystems. In the lesson presented in this article, students conduct investigations using…

Understanding natural selection and adaptation are important precursors to learning evolution (NGSS Lead States 2013), the central unifying principle of biology. This lesson sequence, guided by the Five Practices Model (Cartier et al. 2013), incorporates data described by Andersson (1982) that details female choice in a population that eventually…

Science is full of amazing facts, but at times it may be difficult to fully appreciate their significance without an understanding of the scientific practices that gave them meaning. The teaching of evolution may be an example of this situation; there are many interesting facts to consider, but it is equally important for students to learn where…

The lesson set in this article describes an introductory learning experience using wildlife camera-based citizen science projects hosted on Zooniverse (http://www.zooniverse.org). Wildlife camera projects were chosen due to the charisma of the study organisms, student engagement while looking at images, ease of access to projects, ease of teaching…

Research shows that students exposed to career and technical education are more likely to graduate from high school, attend college, and earn higher salaries than those who do not (Dougherty 2016). Job-shadowing experiences like those at the High School Zoo Academy in Omaha, Nebraska, can help adolescents identify their career goals and understand…

A lesson that focuses on the intricate co-evolution of flowers with their pollinators is one way to help students learn the delicate balance in nature and help ensure that our actions do not upset this balance. In this lesson students use the engineering design process to engineer a flower that is a perfect model for its chosen pollinator. Next,…

Polychlorinated biphenyls (PCBs) are a family of synthetic chemicals consisting of carbon, hydrogen, and chlorine atoms. PCBs have been produced commercially since 1929 in hundreds of industrial applications. Their continued production in the United States was phased out in the late 1970s, and strict disposal guidelines were regulated as adverse…

Many ground-dwelling amphibians, reptiles, small mammals, insects, and other arthropods seek cover during their resting hours. Their natural hideaways include underground burrows, rotting logs, and leaf litter, which are widely distributed and difficult to discover and observe. To make observation easier, scientists, educators, and students can…

Animal biology is fascinating for its incredible diversity in life strategies. These strategies amaze scientists and can also fire the enthusiasm of science students. One group of animals impressive in this way is the phylum "Cnidaria," containing some 10,000 invertebrate species that include jellyfish, corals, sea anemones, hydroids,…

The fruit fly ("Drosophila melanogaster") is an ideal subject for studying inheritance patterns, Mendel's laws, meiosis, Punnett squares, and other aspects of genetics. Much of what we know about genetics dates to evolutionary biologist Thomas Hunt Morgan's work with mutated fruit flies in the early 1900s. Many genetic laboratories…

In 2018 the Gulf coast of Florida suffered extensive damage from harmful algal blooms (HABs), from as far north as Clearwater Beach south to Naples. The bloom lasted nearly a year, picking up in intensity during the late summer months. HABs occur when conditions such as reduced salinity, higher water temperatures, light saturation, and currents…

When asked about protein, students often mention meat, protein bars, and protein's role in building muscles. Many students are not aware of the most basic function of protein: linking genes and traits. Because of its importance in molecular genetics, protein function is included in the life sciences section of the "Next Generation Science…
