Product Description
A shooting star is not a star - it's not a "star" at all!
A shooting star's a meteor, heading for a fall.

These Concept Comparisons consists of three Frames. The first contrasts comets, asteroids, meteoroids, meteors, and meteorites. The final contrasts types of meteorites: stony, iron, and stony-iron.

The middle asks the Essential Question: How serious does an asteroid threat have to be before action is taken? To help communicate the hazard, the Torino Impact Hazard Scale assigns an integer and a color code. This concept comparison frame contrasts from "zero" to "extinction-level event"!

The Frame Routine is a strategy designed to assist students as they organize topics, main ideas and details about reading assignments. This technique includes a basic hierarchic graphic organizer called a "Frame" that can be used to help students think and talk about the key topic and essential related information.

Personally, I use the Concept Comparisons and Frame Routines to figure out what I want to say and how I want to say it to students. It keeps my "Sage on the Stage" time limited to what fits onto a page (about 30 minutes of directed class discussion).

This product includes the completed routines, and the student guide blanked except for vocabulary, scaffolding questions, and graphics already filled in. It is in Microsoft Word .doc form so that Ts can customize the discussion to fit the needs of their Ss.

This product also includes a Line-Up activity to have team members make a human model of a comet; and a scale diagram of a meteorite impact. They randomly select a role to play, and sequence themselves correctly to check comprehension of the anatomy of a comet, or the transition from an asteroid to a meteoroid to a meteor to a meteorite in a crater.

These Routines are classroom tested to help students with the following Florida Next Generation Sunshine State Standards in Science. Students Will Be Able To (SWBAT):
SC.8.E.5.3 Distinguish the hierarchical relationships between planets and other astronomical bodies relative to solar system, galaxy, and universe, including distance, size, and composition.
SC.8.E.5.4 Explore the Law of Universal Gravitation by explaining the role that gravity plays in the formation of planets, stars, and solar systems and in determining their motions.
SC.8.E.5.7 Compare and contrast the properties of objects in the Solar System including the Sun, planets, and moons to those of Earth, such as gravitational force, distance from the Sun, speed, movement, temperature, and atmospheric conditions.
SC.912.N.4.1 Explain how scientific knowledge and reasoning provide an empirically-based perspective to inform society's decision making.
