Learners will use direct vocabulary instruction to learn the new definitions of planet, dwarf planet, and asteroid. The publicity generated by the International Astronomical Union's definition of Pluto as a dwarf planet in 2006 created a teachable... (View More) moment for schools around the world to consider the definitions of these concepts and how discoveries necessitate a change in the language we use to talk about it. (View Less)

Learners will research and document some of the requirements for mounting an expedition to an asteroid; actively explore potential resources available to space travelers through research, assessment, team cooperation, and exploration simulations;... (View More) develop the background to make the connection between meteorite research and potential planetary resources; and map and core an edible asteroid. Materials lists, and advanced preparation and procedural tips are included. This is lesson 17 of 19 in Exploring Meteorite Mysteries. (View Less)

This is a lesson about the effects of large impacts. Learners will use critical thinking skills to evaluate and apply data from a narrative to a scientific selection process, will demonstrate or visualize simulations of some of the effects of a huge... (View More) impact, and will write a point of view narrative. Materials and vocabulary lists, and advanced preparation and procedural tips are included. This is lesson 14 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)

Learners will conduct an investigation, observe and record the physical characteristics of an unknown rock (meteorite), determine the mass of the unknown rock using math skills, determine the density of the rock, describe and classify a meteorite,... (View More) apply observations and knowledge to the process of a scientific investigation, present evidence to verify classification decisions, and explore concepts of spatial relationships. Completion of all parts of the lesson is necessary to identify the unknown. Advanced preparation and procedural tips are included. This is lesson 13 of 19 in Exploring Meteorite Mysteries. (View Less)
