Introduction
In this lesson you
introduce your students to the Satellite
Rescue mission. Raise student motivation and
keep it high throughout the entire
experience by setting the stage for your

presentation provided as a tool to introduce
the scenario to your students. Your students
will learn the context of the mission and
the roles they will have on mission day.

Teacher Preparation
- Read the
mission scenario and mission briefing
PowerPoint to become oriented with the
Satellite Rescue mission.
- Read and become
familiar with the vocabulary section of this
lesson.
- Set up a
computer, projector, and screen to present
the PowerPoint.
Procedure
- To get students
thinking about the mission, ask the
following questions:
- What is a
simulation? A simulation is an imitation
of a real event that allows participants
to experience an activity in a safe
environment.
- How are simulations
used? Simulations are used to help
people prepare for emergencies and to
teach them how to react in real-life
situations. In simulations people can
make mistakes in a safe environment and
learn from them.
- What are some ways
in which we can prepare for our
simulation? Class members can practice
the math skills they will encounter in
the mission and practices the jobs they
will have on mission day.
- Introduce the
vocabulary words to the students and discuss
the meanings.
- Show the
PowerPoint presentation to your students.
- Allow time for
questions and discussion.
Discussion Tips
The main idea they
should get from this lesson is that they are
going to be part of a simulation that has a
specific storyline. Discussion of the
storyline will create the context for all of
the facts and concepts to which they will be
introduced. Special Comments
This class is one of the
most important in terms of student
motivation. As the “movie director,” you set
the scene, create the story, and help your
“actors” prepare for their roles.
