Whip Up a Mouth-Watering Meteorite Activity
A recent meteorite discovery on Mars and an edible classroom activity provide a scrumptious
way to kick off the new school year with a meteorite activity.

This lesson has been designed as a comfortable introduction to describing meteorites. It helps students become better observers by making a connection between the familiar (candy bars) and the unfamiliar (meteorites). Edible "rocks" are used in a scientific context, showing students the importance of observation, teamwork and communication skills. In everyday terms, students draw and describe the food. Students will pair their observations with short descriptions that are in geologic "Field Note" style. As the teacher and class review, appropriate geologic terminology may be substituted by the teacher and subsequently embraced by even very young students. The last part of this activity allows the student to describe rock specimens before they move to meteorite samples in the Meteorite Sample Disk.
