Who are the nearest neighbors to the solar system? This Concept Comparison Frame looks at 376 stars within 32.6 light years of the Sun to find out whose hot, whose not, and whose just right to support life in the "Goldilock Zone".
Included is an m&m math activity on mean, median and mode. It can be used to scaffold the concept from the population of certain candy colors to the census of stars near to our Sun in the Milky Way.
The Concept Comparison Routine is used help compare and contrast key concepts. Specifically, students use like and unlike characteristics and categories shared and not shared by two or more concepts to better understand the overall concept. Students taught using the Content Enhancement routines earned higher total test scores than did students taught using the lecture-discussion method.
Personally, I use the Question Exploration Routine to figure out what I want to say and how I want to say it. It keeps my "Sage on the Stage" time limited to what fits onto 2-3 pages (about 45 minutes of directed class discussion). This product includes the completed question exploration guide, and the student guide blanked except for vocabulary, scaffolding questions, and graphics already filled in.
And it is in Microsoft Word .doc form so that Ts can customize the discussion to fit the needs of their Ss.
This Question Exploration 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.5.5 Describe and classify specific physical properties of stars: apparent magnitude (brightness), temperature (color), size, and luminosity (absolute brightness).
SC.8.E.5.6 Create models of solar properties including: rotation, structure of the Sun, convection, sunspots, solar flares, and prominences.
SC.8.P.9.2 Differentiate between physical changes and chemical changes
SC.8.L.18.2 Describe and investigate how cellular respiration breaks down food to provide energy and releases carbon dioxide.
SC.912.E.5.3 Describe and predict how the initial mass of a star determines its evolution.
SC.912.P.10.11 Explain and compare nuclear reactions (radioactive decay, fission and fusion), the energy changes associated with them and their associated safety issues.
SC.912.P.10.12 Differentiate between chemical and nuclear reactions.
NGSS. HS-ESS1-1 Develop a model based on evidence to illustrate the life span of the sun and the role of nuclear fusion in the sun’s core to release energy that eventually reaches Earth in the form of radiation.
