NGSS

MS-LS1-7
Primary
Develop a model to describe how the respiratory system functions.Reason: This standard is directly related to the task of creating a model of the respiratory system, which is the main objective of the project.
MS-LS1-3
Secondary
Use argument supported by evidence for how the body is a system of interacting subsystems composed of groups of cells.Reason: Understanding the respiratory system as a subsystem helps students grasp its role in the larger function of the body.

Common Core Standards

CCSS.ELA-LITERACY.SL.8.1
Supporting
Engage effectively in a range of collaborative discussions on grade 8 topics and texts.Reason: Students will need to communicate and collaborate during the model creation process, making this standard relevant.

Entry Events

Events that will be used to introduce the project to students

Crisis in the Lungs

Present a scenario where students are tasked with solving a mystery involving a sudden outbreak of a fictional respiratory illness. They'll research symptoms and the respiratory system to create a diagram of how the disease progresses, using this as a baseline for their model that demonstrates preventative measures or treatment.
