This grade 6–8 reading introduces students to the cutting-edge science of gene-edited pigs and xenotransplantation and how scientists are working to use animal organs to save human lives. It explains what xenotransplantation is, why there is a global organ shortage, and how gene editing is being used to make pig organs safer and more compatible for human transplants.

The article breaks down DNA, gene editing, CRISPR, immune rejection, and organ compatibility in clear, student-friendly language, helping learners understand how scientists can change pig genes to reduce rejection and improve transplant success.

Students will explore real-world examples of pig heart and kidney transplants, diabetes treatment using pig cells, and future medical possibilities, while also examining the benefits, risks, and ethical questions surrounding this technology. The reading encourages critical thinking about science, responsibility, animal welfare, and how medical advances can shape the future.

This resource is perfect for life science, genetics, biotechnology, health science, or STEM classes and supports both content learning and scientific literacy skills.

Praise For My Other Reading Comprehension Resources:

"I teach middle school science and need to include informational text in my classroom. These readings are great for independent reading for my grade-level and upper-level readers. The articles address CCSS.ELA-Literacy.RST.6-8.1 (Citing specific textual evidence to support analysis of science and technical texts.) and CCSS.ELA-Literacy.RST.6-8.10 (By the end of grade 8, read and comprehend science/technical texts in the grades 6-8 text complexity band independently and proficiently.). The leveled questions allow you to subtly assign the questions to different ability students working in a group.

Topics are relevant to the students and current. Graphics draw the students into the article. I'm going to have one printed and waiting in for my substitute folder too!

THANKS!"

"Thanks for putting together a wonderful resource."

"I teach Special Education high school science in Maryland in a special school for children with learning disabilities/Autism. I liked the readings and I think students could relate to the topics. I know these are too high a reading level for most of my students and I would read it out loud and highlight the important information together. I would not be able to use the higher-order thinking questions (which I like) with these kids. For my high students (very few of these in my school :), I really like these especially how you noted where you got the information which if they were inclined, they could go back to the original source. I like that you have scaffolded the questions and I would only be able to use these with a handful of students, but I think in a regular high school classroom (I spent many years in regular ed) these are spot on. Thank you for sharing."

We don't spend enough time teaching scientific literacy to our students. This is either because we don't have the resources to do so effectively or we don't have the time. However, teaching our students to become scientifically literate is vital if we want them to succeed in life. We need them to know about the world they live in and about the issues they face.
