This one page reading comes with a 4 question reflection/understanding check at the end. The reading explains why our immune system does not always recognize cancerous cells. The reading lightly explains the immune system and cancer to preface learning about why cancer can be so hard to detect. The title "Sneaky Cancer Cells" is designed to help students form a connection between the reading and the title - answering the question - how can cancer cells be sneaky? I hope this short reading will help students understand why our immune system sometimes needs help in fighting cancer (and I hope it helps answer the question of if our immune system can fight it at all).
The questions at the end have been double printed so that you can save paper. Simply print and cut in half to distribute to students. If students do work in interactive science notebooks, the small size of the questions sheet will allow students to cut-and-paste it into their notebooks as well.
Enjoy! Please let me know what you think, and how your students responded to the reading!
