| This science module focuses on the relationship
between basic chemistry concepts and the information that
will be returned by the Genesis mission. If you are using
Genesis science modules for the first time, read the User's
Guide thoroughly before you begin. (View User's Guide
as a PDF.)

 Elements
are explored from various perspectives in this science
module. During the exploration, students group elements
by their characteristics much like Dmitri Mendeleev did
in the 19th century. Students will interact with others
by finding out about elements in particular groups. Using
several resources, students will learn how elements are
currently being used in products found in everyday life.
Genesis scientists want to learn about the building blocks
of our solar system. The "Elemental Mysteries for
Genesis Scientists" student text engages students
in the questions these scientists are asking. Finally
students create mathematical models to explain differences
in chemical reactivity among elements. Using their models,
students will interpolate characteristics of a hypothetical
element in the assessment activity. |

| The teacher text contains content
information on atoms, elements, the periodic table, isotopes
and the Genesis mission. Although written for the teacher, this
text could be used in total or in part for students after they
have completed the interactive simulation. The module planning
guide contains information about the entire module. This grid
has been set up to give teachers the tools necessary to teach
the module at a glance. Students
will develop an understanding of the Sun’s solar wind,
the Earth’s magnetosphere, and how the Genesis spacecraft
collected solar wind at L1. |

Students learn about the periodic
table by patterning the same approach that Mendeleev used in
the 19th century using an interactive simulation. The simulation
may be completed using element cards without the computer with
Making Sense of the Elements. The interactive simulation can
also be run live off the Web site or downloaded to
student computers with Interactive Simulation. The teacher guide
for each of these contains complete lesson plans for each option.

Students complete reading exercises
to learn more about the development of the periodic table, how
it is used today and what Genesis scientists hope to contribute
to our understanding of the elements.

 Students
will use the Internet and other sources to locate information
about one element. They will then share the information
about their element with their group (family) and with
the class.

From the Cosmic
Chemistry: An Elemental Question module, students initially
meet in lab groups to discuss information provided about a
subset of the elements. They finish the assessment individually,
creating a mathematical model to explain differences in chemical
reactivity among these elements, analyzing the process of developing
this model, interpolating from their model the characteristics
of a hypothetical element, and planning a presentations to
their peers on their model. |
