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) relate meteorites to the core, mantle and crust of asteroids, and model the break-up of differentiated planetary bodies to expose the interior layers. Materials lists, and advanced preparation and procedural tips are included. This is lesson 11 of 19 in Exploring Meteorite Mysteries. (View Less)

This is a lesson about the connection between meteorites and asteroids, focusing on remote-sensing techniques using light. Learners will make and record observations and measurements; analyze data and draw analogies; compare samples; measure and... (View More) record the brightness of spectral light; discover the composition of white light; participate in introductory quantitative spectroscopy experiments; set up, conduct and analyze a reflected light experiment; and recognize/discover that different materials reflect different proportions of incident light. Activities, vocabulary words, and experimental extensions are included. This is lesson 5 of 19 in Exploring Meteorite Mysteries. (View Less)

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) shapes of orbits in the solar system (Activity A); construct a scale-model of the inner solar system, observe relative distances and sizes, plot paths meteoroids might take and manipulate models to demonstrate the ecliptic plane (Activity B); and graph the locations of Earth and a near-earth asteroid, observe the significance of time and space, and estimate when the asteroid might cross the orbit of Earth (Activity C). Activities, vocabulary words, and experimental extensions are included. This is Lesson 4 of 19 in Exploring Meteorite Mysteries. (View Less)

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) conduct controlled experiments using mass and velocity as the independent variables. Energy calculations for advanced classes, and vocabulary words are included. This is lesson 6 of 19 in Exploring Meteorite Mysteries. (View Less)
