In this Click & Learn, students explore mathematical models that describe how populations change over time and apply these models to the invasive lionfish population in the Bahamas. They also use data from other species to learn how density-dependent factors limit population size.
Genetics and patterns of inheritance are key topics to cover in a biology course. In this article by Cinthya Fernández, who teaches in Mexico, see how she sequences our genetics resources for her introductory and advanced high school biology classes.
This activity explores images of elephants with and without tusks, which serve as phenomena for learning about selection and human impacts on the frequency of traits within populations.
It is rare for a single phenomenon to span a large range of concepts. In this Educator Voices article, professor Holly Basta explains how to utilize our sickle cell resources to teach a variety of topics including the central dogma, gene therapy, Mendelian genetics, and evolution
In this activity, students find a scientist with whom they can relate in some way and then explore and reflect upon the impact of that scientist’s work.
This film explores how life recovered after an asteroid wiped out the dinosaurs and how those events shaped the diversity of plants and mammals on Earth today.
Scientists say they have used the gene editing tool CRISPR inside someone’s body for the first time, a new frontier for efforts to operate on DNA, the chemical code of life, to treat diseases.
This video case study explores the approaches scientists used to identify a mutation that causes retinitis pigmentosa (RP), a progressive disease that leads to blindness.
