Humans have modified organisms for millennia through selective breeding and other techniques. But only in the past few decades have people gained the ability to directly alter organisms’ DNA to create Genetically Modified Organisms (GMOs). GMOs can help advance fields such as medicine and agriculture. In this activity, students will learn more about GMOs and their uses before creating an awareness campaign to address GMO misconceptions.

Scientists are still chipping away at the challenge of completing the puzzle of human genetics. Draw diagrams of DNA, chromosomes, genes and other genetics terms to review their relationships before piecing together the new findings of recent studies that fully sequenced Y chromosomes for the first time.

Light up your class with examples of fluorescence, including recently found biofluorescence in many frog species. Learn about the discovery of fluorescing frogs, discuss the potential evolutionary advantages of fluorescence, answer questions about the chemistry behind fluorescence and perform a demonstration of fluorescence from common objects.

Students will analyze a graph to identify inequities in COVID-19 vaccine access among nations based on wealth, discuss how affluence affects access to and distribution of vaccines as well as how disparities in vaccine distribution affect global pandemic recovery. Students will then work in groups to research COVID-19 vaccine access and distribution in their state or local area, identify potential inequities in vaccine access and distribution and construct a graph of their own.

Students will think about how communities connect on local and global scales through the lens of COVID-19 vaccine distribution and consider why global collaboration in STEM is crucial for solving some large-scale issues.

Students will answer questions about the online Science News article “Global inequity in COVID-19 vaccination is more than a moral problem,” which explores the scientific and economic impacts of the failure to fairly distribute vaccines globally. A version of the story, “Vaccine inequity will prolong pandemic,” appears in the March 27, 2021 issue of Science News.

Students will imagine that they are officers at the World Health Organization and will work in groups to develop action plans to prevent the spread of a new virus, such as coronavirus.

Students will explore the definitions of outbreak, epidemic and pandemic and research how an outbreak becomes an epidemic or pandemic.

Scientists would like to breed cats that don’t trigger allergies in people. By constructing and analyzing a Punnett square for two low-allergen cats, students will review key concepts including patterns and probabilities of inheritance, genotype, phenotype, genes, alleles, chromosomes and mutations.

Students will answer questions about the Science News article “How to lick cat allergies,” which explores some potential solutions to prevent and calm allergic reactions.

Students will identify and categorize various approaches to fending off cat allergies. After discussing the approaches, students will apply similar problem-solving strategies to a new allergen.

These discussion prompts explore how genetic engineering has been used in medicine, agriculture and basic research.
