Reflection: Lesson Planning Asteroids, Meteors & Comets - Section 3: Part 1 (Comprehension - Visualization - Demonstration)


A fun and memorable demonstration for this lesson is to construct a model composed of materials similar to that found in an actual comet. Due to the safety of handling dry ice, it is safer for the teacher to prepare the model.

However, if you use enough materials you can make small comets, enough for one for each table group to observe. When building these I place them on to a tray then go over some basic safety with my students before setting the trays on each of the lab tables. Students can observe the comet sublimating as the gas goes solid to vapor and you can discuss the purpose of the other materials that are part of the ingredients of the model. The National Optical Astronomy Observatory has a resource with directions for creating this demonstration.

Asteroids, Meteors & Comets

Unit 8: Where Is Earth In Space?
Lesson 7 of 10

Objective: SWBAT compare and contrast the physical properties and locations of asteroids, meteors and comets.

Big Idea: Through this series of activities students will be able to explain the differences between these three objects.
