This investigation introduces students to the phenomena of urban heat islands, areas of higher then normal temperatures associated with populated areas. Using Atlanta, Ga., as the study site, students begin by analyzing the population growth and... (View More)

This is an activity about gravity. Learners will design their own experiments to explore the fundamental force of gravity and then extend their thinking to how gravity acts to keep objects like moons and ring particles in orbit. They use the... (View More)

This is a lesson about planet formation. Learners will observe and describe differentiated samples in the Meteorite Sample Disk (or photographs), conduct experiments to model the separation of light and heavy materials within a planetary body,... (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 is an activity about the expansion of the Universe. Learners will use a special set of transparency and master sheets with dots representing clusters of galaxies at two different eras of the Universe's history. After aligning the transparency... (View More)
