
Utilize scientific inquiry to explore the effect of microgravity on
pathogenicity and virulence of bacteria.
Debate the importance of the research on virulence of bacteria
in space in order to build a ‘big picture’ understanding of effect
of scientific inquiries on the course of humanity
Note: Teacher implements a project-based learning approach to help
students gain awareness of and insight in processes of inquiry, scientific
principles of gene expressions and their effect on subsequent
populations, and influence of scientific endeavors on a progress of
humanity beyond the realm of our existence on Earth.
Resources Needed:

Easel pads and markers to create a semantic/web map during
the brainstorming phase
o Access to www and printed materials organism and
population genetics, molecular biology
o Access to various ‘design’ applications such as Google

alternatives pathways (If this does not work, then change
…because…)
d) Construction of a prototype of the testing mechanism using
real or digital materials
2) Clear comparison and analysis of experimental designs proposed
by students and scientists, incorporating evidence of:
a) Understanding that gene expression in Salmonella
typhimurium (and in any other organism, including humans
immunological response) is a process regulated by
environmental agent, such as microgravity, radiation, lack or
presence of chemical agents in surrounding
b) Planning further inquiry on why/how homeostasis may be
factor in the response of humans and bacteria to
microgravity
c) Planning further inquiry on to what degree each of the
aforementioned factors plays a role in the change of the
population of Salmonella typhimurium



Sketch, Minecraft
Access to various ‘presentation’ applications such as Prezi,
Glogster, Google presentation, Animoto
Commonly available items of students’ choice
Access to the Lego Mindstorms for students who might want to
design a robot as an alternative to eliminating a human contact
with the pathogens onboard the ISS
3) Argumentation in the debate on whether the space flight research
in pathogenicity/virulence is worth federal investments,
incorporating evidence of:
a) Understanding the effect of scientific research on space
exploration and future of society
b) Understanding the effect of scientific research on predicting a
course of evolution
c) Understanding the connection between scientific research
and medical advancements

Teacher Procedure
Brainstorming: In groups, students discuss, and if necessary, research auxiliary
information to the question: Why do organisms, including humans, become sick? The
process of brainstorming should be visualized by creation of a semantic map/web in
order to narrow down subsequent focus to bacteria. It is crucial that students realize
prior to watching the video that pathogenicity is comprised of physical interactions
between an agent and a host, and that chemical response pathways of each of the
players involved are different. Pathogenicity leads to virulence once the pathogen
successfully enters a host system and begins to replicate.
Show this first segment of the video to your students, letting them know that they will
be working on solving the real-world problem after viewing.
In groups of 3-5, have students begin working on the experimental design by:
 Identifying a valid research questions
 Discussing and identifying valid assumptions associated with listed constrains
based on the research information gained during the Activator phase
 Clearly stating and justifying choices of independent and dependent variables, a
control, and constants reached on the premise of the assumptions
 Using an easel pad or technology to create a flow map of procedural steps,
including a brief reasoning behind a choice of each step. Alternative pathways
may be included at this point.
 Presenting the flow maps of the groups to other class members followed by
subsequent class discussion leading to a consensus on plausibly realistic and

workable designs
Creating the plausible prototypes/models of mechanisms presented in the
experimental design(s) accepted by the class.
Checks for Understanding
 Teacher monitoring students’ progress during the group work
 Final presentations

identifying possible
solution(s) to the problem

Grouping:
Independent
Pairs
Small groups (3-5)
Whole group
Show this second segment of the video to your students, letting them know that they
will be comparing their solutions to the actual solution shared by the industry
professional(s).
In the small groups, have students compare and contrast the experimental design
proposed by them with the design presented by the scientist. In the steps leading to the
comparison, students should:
 Reach consensus on the most useful graphic organizer(s) to analyze and
compare the designs
 Provide reasons why each of the steps proposed by the scientists may be a
proper solution
 Critically analyze and discuss whether the steps proposed by students could be
utilized by the scientist, and how the students would logically convince the
scientist that their ideas may work as well
 Present analyses and proposals via a gallery walk. Each student may leave
constructive feedback/suggestions for improvement on their peers’ proposal.
Checks for Understanding
 Peer-assessment in form of feedbacks written on sticky notes on the gallery
walk displays
 Teacher verbal feedback presented to the groups

After reflecting individually on the presentation by the scientists, have students
participate in a debate on whether the research on the virulence of bacteria in the space
flight should be federally funded. The debate should lead to the expansion of students’
awareness of importance of the current research into development of treatment of
diseases, genetic engineering of gene expression pathways, deep space exploration - for
which each shapes the future of humanity.
As an extension of the debate, students individually reflect on how they may help
scientific endeavors in a genuine letter/email written to a real scientist of their choice.
In their correspondence, the students also ask questions which interest them.
