Lesson: Sex, Genetics & Athletics from PGED

This lesson uses athletics as a lens to examine the biology of sex differences, and how societies react to individuals with these differences. Through readings, slides and discussion, students will examine the history of sex confirmation in elite athletic competition and learn why dividing people into two sexes is not as clear-cut as it seems. Students consider the practice of defining sex by anatomy, DNA, and hormones and then think about the various viewpoints on fairness, diversity and inclusion in sports and society. The classroom activity asks students to imagine being a doctor responsible for verifying the sex of athletes in an international track and field competition while considering the realities of genetic complexity as well as the impact of their decisions on athletes and other stakeholders.

The lesson plan includes a Do Now, slideshow, and a classroom activity.

There is also video lesson that includes a Do Now question and prompts to pause and answer questions.

Personal Genetics Education & Dialogue (PGED) raises awareness about genetics and discuss how genetic technologies impact people’s lives now and in the future.

Mini-Unit: Hybrid Zones, Evolution's Testing Grounds

In this set of three lessons from Galactic Polymath, students will learn that hybrids are not flukes—they’re commonly found in the wild and our grocery stores! By playing and reflecting on Foraging Frenzy (a research-inspired memory game) students will appreciate how climate change affects species ranges and the direction of evolution.

Students will be exposed to diverse scientific researchers, including a queer scientist who reflects on his journey and the impact of role models.

High School NGSS-aligned activities on Life Cycles, Inheritance, Animal Behavior, and Sex Development

Thank you for your interest in the Inclusive Biology Curriculum Research Project. I am Charlie Blake (they/them), an Assistant Research Professor at Southern Illinois University Edwardsville. I am leading a research study along with contributions and support from partners and advisors, including the folks at Gender Inclusive Biology (https://www.genderinclusivebiology.com/). I am currently recruiting high school life science teachers for the 2024-2025 school year. If you are able to participate, I would supply you with four activities (NGSS-aligned) that you would use whenever they fit into your teaching schedule. I would then invite your class to participate in some short pre- and post- surveys and invite a few students in each class to do interviews. The topic areas of the lesson materials are: Reproductive Life Cycles, Genetic Inheritance, Animal Bodies and Mating Behavior, and Sex Determination and Development. Even if you can’t do all the lesson topics you can still participate. A small stipend is available for all participating teachers!

“Inclusive Biology Curriculum Impacts on Students” IRB approved protocol #2171

If you would like to use the lesson plans but are unable to participate in the study, I will still share the activities with you, but I hope you will consider joining the study!

Ancient Skeletal Remains: Sex, Gender, And Archaeology

In this lesson for high school life sciences, students explore case studies of human remains that have challenged scientists’ ideas about how gender and sex operated in ancient times to help us better understand how gender, sex, and sexuality change our bodies and our stories in the present day.

Lewis Steller created this lesson as part of the Science Friday Educator Collaborative.

American Psychological Association's Four-Lesson Unit on Gender

This unit for high school psychology classes covers four topics:

• Gender as a Biopsychosocial Construct

• Cultural and Historical Considerations about Gender

• The Importance of Pronouns

• Seeking Support at School

Differences in Sex Determination Investigation

Alex Maes created this investigation which includes a variety of videos and infographics also featured on this website. Two versions are available, one more scaffolded than the other.

Alex writes:

I've made a lesson like this too using lots of resources from genderinclusivebiology.com, as well, as some of my own. I have an individual, less scaffolded version I do with my IB juniors, and a more scaffolded version with whole class, individual, and small group components I did with my freshman! Feel free to use!

Edit (6/8/23): Thank you to Wayne for noting the lesson materials include diagrams including humans in a chart entitled hermaphrodites. It is important to discuss with students how language changes when describing human versus non-human species because of how “hermaphrodite” was historically used as a pejorative to stigmatize people. Wayne provided the link embedded in the disclaimer most frequently seen on related GIB posts: Editor’s note: The term "hermaphrodite" is appropriate for referring to non-human animals with sex characteristics that do not fit typical binary notions of male or female bodies. For humans, “intersex” is the appropriate term—learn more here! (-RXS)

Inclusive Genetics Activities by Elizabeth Duthinh

Elizabeth Duthinh, a physician and high school teacher, developed these inclusive activity and practice problem sets covering the Monohybrid Cross, Dihybrid Cross, X-linked Traits, Non-Mendelian Inheritance, and the PTC taste lab.

Elizabeth writes:

These problem sets and PTC tasting lab are adapted to cover Mendelian genetics without presuming gender based on chromosomes and without assuming families and individuals are cisgender or heterosexual. We suggest pairing the X-linked characteristics problem set with the video What it's Like to be Intersex by InterACT and a short introduction to the SRY region of the Y chromosome.

Sex Determination and Non-disjunction Lesson by Sabrina Kayed

This highly accessible lesson was designed by Sabrina Kayed for Grade 11 Biology. The lesson is designed to move students’ understanding of biological sex beyond the simplistic binary model and introduce them to the idea of sex as a spectrum.

Teaching about Gender Diversity (Book)

Written by teacher for teachers, Teaching about Gender Diversity is an edited collection of interdisciplinary lesson plans that provides K–12 teachers with the tools to implement gender-inclusive practices into their curriculum and talk to their students about gender and sex. Edited by Susan W. Woolley and Lee Airton, this engaging collection features teachers' perspectives on teaching about gender from across North America. Divided into three sections dedicated to the elementary, middle, and secondary grade levels, this practical resource provides lessons for a variety of subject areas, including English language arts, STEM, and health and physical education. To view more titles in Education, visit canadianscholars.ca.

Sexing skeletons: the biology of sex, gender, and the incredible diversity of human biology

In this blog post, Gender-Inclusive Biology contributor Lewis Maday-Travis shares a presentation he created to wrap-up a unit on the skeletal system. The presentation focuses on the science of the intersex experience and nonbinary identity, both of which are supported by scientific research yet frequently erased in public discourse.

Lesson Plan: Animal Patterns of Reproduction

In this lesson, students learn briefly about the reproductive strategies nine different animal species. Student use a tally to track what strategies are most common - for example, male competition, female mate choice. More unique patterns like sex-changing clownfish and touch-mediated sex development are included within the nine species.

When I taught this lesson, students learned about each species through short video recordings of teachers in our school describing the species. For more general use, I changed the lesson as posted on this website to have students do online research instead of watching the videos.

LGBTQIA Science/STEM Etymology

This is a partial list of root words that occur in both LGBTQIA issues and STEM content. Each root word has its own poster. This is a tool to help teachers integrate gender-inclusive themes into their teaching.

You might ask students to speculate on the meaning of a new science word like “homozygous” based on the meaning of the familiar word “homosexual”. Or you might have students write formal definitions of “transgender” and “cisgender” to apply their vocabulary after a lesson on cis- and trans-isomers. By taking a quick moment to make the connection, you can improve student literacy and affirm diverse identities in your classroom.
