Wow your students with the Human Body Systems Reading Comprehension CSI Spy Mystery! Students will complete 4 reading comprehension tasks all while playing detective and finding clues to the case. Students will LOVE this close reading challenge! Great addition to your biology unit.

Topics include: human body systems, Skeletal system, Muscular system, Cardiovascular/circulatory system, Digestive system, Nervous system, Respiratory system, Endocrine system, Urinary system, Immune/lymphatic system, Reproductive system, and the Integumentary system.

Students will work individually (or in pairs) and race to see who can solve the case first! A friendly competition always increases engagement. After completing each “task” students will earn a “CLUE CARD” to help them eliminate suspects and evidence.

As students complete each task, they will bring you their answers for you to quickly check (don’t worry…each task is short). After checking, students will earn a “CLUE CARD” with clues to solve the case.

This activity can be used for individual work, partner activities, anticipatory sets, unit review, sub plans, extension activities, early-finishers, or just for fun the day before break.

A “Top Secret Case File” is read and your “lead detectives” have less than an hour to solve the case. (Time can be changed to whatever works best for you)

Oh, and before I forget…there’s also props included to make it feel like a “crime scene” and signs to hold up at the end when the CSI mystery is solved!
