This is a lesson about gathering information, applying scientific identification processes, and identifying unknown rocks. Learners will conduct an investigation, observe and record the physical characteristics of an unknown rock (meteorite),... (View More)

This is a lesson about mapping objects using triangulation. Learners hunt distant meteorites using geometric properties and relationships, demonstrate and experience triangulation, and apply triangulation to directed and group-challenge mapping... (View More)

This is a lesson about the path meteorites take to get from the asteroid belt to Earth and how rare it is for the Earth to be hit by a large asteroid. Three activities comprise the lesson. Learners will draw circles and ellipses to illustrate basic... (View More)

This is a lesson about impact craters; the relationships between crater size, projectile size and projectile velocity; and the transfer of energy in the cratering process. Learners will create plaster of Paris or layered dry impact craters and... (View More)

This math example shows how to calculate the distance one can see from different heights using trigonometry. This resource is from PUMAS - Practical Uses of Math and Science - a collection of brief examples created by scientists and engineers... (View More)

In this activity, learners build a sextant to measure the altitude, or height above the horizon, of an object. The activity was originally designed to accompany a previous NASA-funded educational program, entitled The Sun in Time.

In this introductory global change investigation, students gather and record visual and written data from their surroundings, and through analysis, show how the sampling window chosen for examination can affect an outcome, sometimes resulting in... (View More)
