Audience: Middle to high school
Time Needed: 60+ minutes (activity
can be stretched over multiple days)
This activity involves students in a mock legislature, defined to be any decision-making body consisting of elected representatives. Students will be asked to consider the effects of using nanotechnology on different segments of society, and then decide as a class whether or not nanotechnology should be used. A suggested scenario and group roles are included in the supplementary materials, but the instructor should feel free to make modifications and additions to the activity as appropriate for the class.
Opening Discussion (5-10 min.):
Show students the pictures of the sheep, the space shuttle, the cell phone,
and the junk e-mail. Ask students to brainstorm what all of these things have
in common. Explain that all of these pictures represent areas of science and
technology that have been affected by, or could be affected by public policy
and law - cloning, the space program, cell phone use while driving, and regulation
of junk email.
Begin a group discussion on the roles society, law, and politics have played in determining the path of science and technology in the past, and in recent history. Technology helps to shape society, and society often shapes technology through laws and regulations. Elaborate on the examples given in the pictures, or use examples from history if you feel it helps to illustrate the point.
Introduce the idea of the legislative process. In the United States, citizens elect people to represent them in lawmaking bodies. These representatives must balance the wishes of the people they serve with their own personal views and the views of any organizations they support. Representatives turn those views of what the government should do into bills - suggested laws. The bills are first sent to committees for study, and then brought to a vote before the entire lawmaking body. Students should understand that they will play lawmakers, who will first study a bill in committees, present their findings, and then vote on the bill.
Introduce and explain nanocomposites. (See article, "Nanocomposites: Coming Soon to a Store Near You"). Outline the role-playing scenario for the students. (See handout, "Welcome to Nanoville!" for details of role-playing scenario.)
Group Preparation (10-15 min.):
Divide students into committees of 3-5 people each. These committees will each
study the effect the law would have on one particular group in society. Students
will be provided a worksheet with questions they should discuss and answer.
The teacher should review each committee's worksheet upon completion. After
receiving educator approval, committees should summarize their conclusions from
the worksheet and make a poster outlining the points they think are the most
important.
Group Presentations (15-30 min.):
Each group will show its poster to the class and make a brief oral presentation
on what they discussed. As an alternative, have the students debate their positions.
Wrap-up Discussion (10-15 minutes):
Bring the class back together and ask students to vote the way they believe
someone in their role would vote. Then lead a discussion on the outcome of the
vote, how the vote will affect scientific research on nanocomposites, the major
issues brought up during the presentations, and what the students learned about
the relationship between science/technology and society/law/politics.
Nanotechnology is currently a hotbed of speculation and scientific research. The prefix "nano" means "one billionth of," as in a "nanometer" is one billionth of a meter. The field of nanotechnology is broad, including virtually everything that deals with manipulating particles on the scale of nanometers - on the molecular or atomic level. Current applications of nanotechnology include uses as frivolous as fabric that cannot be stained and as ubiquitous as LED lighting. Nanotechnology has the potential to improve dramatically the storage and processing of information; the development of nano-engineered sensors that might allow for early tumor detection; the creation of new materials that are stronger and lighter than existing ones; and the increase in energy efficiency of solar cells. Nanotechnology could potentially allow for the development of a continuous, unmanned presence outside the solar system.
