In this three dimensional NGSS assessment, students first apply their understanding of cells, tissues, organs, and organ systems to specific phenomena related to "body invaders" -- viruses that cause disease. Specifically, the assessment focuses on a fictional pandemic -- the emergence of a mutated version of H5N1 Avian Flu that is able to be transmitted from human to human. Then, students prepare a press conference to address fears of the reemergence of this flu years later, combining evidence gathered throughout the unit with their own reasoning and synthesis to reassure the public that when the body is working as it should, it can defend itself against body invaders like the flu virus.
This activity is part of the middle school unit Organization of Living Things: Body Invaders.
This activity bundle is part of a complete unit that builds towards these standards:
Conduct an investigation to provide evidence that living things are made of cells; either one cell or many different numbers and types of cells.
Develop and use a model to describe the function of a cell as a whole and ways the parts of cells contribute to the function.
Use argument supported by evidence for how the body is a system of interacting subsystems composed of groups of cells.
5E Model Phase: Evaluate
>> Students will develop models to explain how viruses invade the body, including all and only relevant components.
>> Students will support the claim that the body is a system of interacting subsystems composed of groups of cells. These cells work together as tissues, organs, and organ systems to carry out the functions necessary for life. One of these functions is to defend the body against pathogens (body invaders like viruses and bacteria).
>> Students will use evidence collected throughout the unit to support their claim.
>> Students will evaluate the strengths and weaknesses of the evidence.
>> I can develop a model to illustrate how viruses invade the body.
>> I can support a claim that the body works as a system to protect itself from body invaders.
>> I can use evidence to support my claim.
>> I can evaluate the strengths and weaknesses of the evidence.

This resource is the culminating assessment for the middle school science unit Organization of Living Things: Body Invaders that addresses MS-LS1-1, MS-LS1-2, and MS-LS1-3. As such, students should have been introduced to the content relevant to those standards. In the complete unit, students have already explored the characteristics of living things, identified the cell as the basic unit of life, and discovered the structures within the cell that support its healthy functioning. The nucleus and cell membrane are particularly relevant to this assessment.
They have also been introduced to the cells, tissues, and organs of the circulatory system — specifically, red blood cells, white blood cells, platelets, blood, the heart, and blood vessels (arteries, veins, and capillaries). Students are also familiar with the types of tissue and where they can be found in the circulatory system. All of this information was covered in the activity bundle, Exploring The Circulatory System.
Students have furthermore discovered how systems - like the circulatory and respiratory systems - interact in Investigating The Body As A System. Likewise, students were introduced to the immune system early in the unit in the activity - Infectious Disease and Body Systems.
All of this learning occurred through the lens of “body invaders” — viruses that cause disease by invading cells and interrupting normal function. Students discovered this content through the activities in the bundle, Is It Alive?: A Closer Look At Viruses.
While it is not necessary to complete all of these activities to use this assessment, students WILL need much of the content knowledge explored in these activities. That said, resources that present this information (texts, videos, etc.) have been linked in the file to provide some background knowledge students may be missing. You can find additional resources in the iExploreScience store on TeachersPayTeachers or at the Science Teacher Tribe.
