Y7 Lifestyle Diseases


Human bodies contain organs. Each organ has a job to do. Organs work together to form “systems”.

Our organs keep us healthy, but we must ensure that our lifestyle choices do not get in the way of staying healthy. 

Teenagers are linked to certain behaviours that will affect their bodies. Changes from within, as well as changes from their surroundings, impact their health. Sometimes, bad decisions are made, and this causes them to become sick.

Guiding Questions

“How do things I do each day affect my health?” 

“Which behaviours are linked?”

“Which organ/s does it affect?”

“Is the damage permanent or temporary?”
