Learners will relate the concept of density to the density of dust in space. They will use mission data from the Student Dust Counter (SDC) data viewer to determine the density of dust grains in a volume of space in order to answer questions... (View More)

Learners will explore how engineers minimize the use of fuel by utilizing gravity. In Activity 1, students explore the physical conservation laws by observing the behavior of balls colliding with other objects. In Activity 2, the students use an... (View More)

This is a lesson about using gravity to assist in spacecraft navigation. Learners will relate an elastic collision to the change in a satellite's or spacecraft's speed and direction resulting from a planetary fly-by, often called a "gravity assist"... (View More)
