Topic 1: DARTing Toward Rendezvous

In order to be prepared for any situation, NASA's planned Orbital Space
Plane will have to be able to fly itself.  Today, engineers are working on a
spacecraft called DART that will make the needed technology a reality.

K-4
Lesson 1 - If I'm Here, Then Where Are You?  To simulate how a Global
Positioning System works.       
               
Lesson 2 - I Need To Get There Quickly!  To find the shortest route between
two places.
       
5-8
Lesson 1 - Making Money With GPS:  To learn about the growth of Global
Positioning System (GPS) use worldwide from 1993-2000, and to graph that
growth.

Lesson 2 - How Do You Get To School?  To learn how a Global Positioning
System (GPS) works, and to use a GPS to create a detailed map of the

Lesson 1 - Programming DART:  To write a computer program for the
Demonstration of Autonomous Rendezvous Technology (DART).

Lesson 2 - Shooting A DART At A Satellite:  To calculate the position of the

satellite using polar and Cartesian coordinates.
       
       
Topic 2: Making Food Count

When John Glenn became the first American to eat in space, some had been
afraid he wouldn't even be able to swallow in microgravity.  Here's a look
at how far this field has come in 40 years.

K-4
Lesson 1 - Magnetic Breakfast:  To extract iron from breakfast cereal.

Lesson 2 - Healthy Food Collages:  To learn the healthful benefits of eating
foods high in iron, calcium, and vitamin C, and to make collages using
pictures of foods that contain these substances.

5-8
Lesson 1 - Crunching On Some Iron:  To determine amount of iron found in
different brands of cereal.

Lesson 2 - Calculate The Calcium:  To calculate the percentage of the
recommended daily allowance (RDA) of calcium for adolescents in food.
