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.

Students will answer questions based on the Science News article "Ban on gene-edited babies proposed."

Students will use resources beyond the article to answer more detailed questions on neuroscience, biochemistry and microbiology.

Students will answer questions based on the Science News article "Parkinson's pathways."

Students will answer questions based on the Science News articles "Flowing toward a sustainable future" and "Mapping stars across generations."

In this activity, students will analyze simulated DNA data from different people to understand how such data can be interpreted and applied.

These discussion prompts examine student knowledge of DNA and genes, and then explore DNA sequencing and gene therapy.

Students will explore and compare articles about genomes in general, and the human genome in particular.

Students will answer questions based on the Science News article "An open book."
