Product Description
How is the Brightness of a Bulb Affected by Distance? This Question Exploration examines this Essential Question, and helps Ss answer the idea of how to increase the illumination of a desktop when they study.

Question Exploration Routines are instructional methods that teachers can use to help a diverse student population understand a body of content information by carefully answering a critical question to arrive at a main idea answer. 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 Routines 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 both completed question exploration guide and the student guides blanked except for vocabulary, scaffolding questions, and graphics already filled in. It also includes recommended activities, video, and a worksheet. It is in Microsoft Word .doc form so that Ts can customize the discussion to fit the needs of their Ss.

These Concept Enhancement Routines have the following learning objectives and outcomes. Students Will Be Able To:
• SWBAT explain explain the relationship between brightness and distance for a light source, and solve problems of

These Concept Enhancement Routines are classroom tested to help students with the following Florida Next Generation Sunshine State Standards in Science:
• SC.7.P.10.24 Observe and explain that light can be reflected, refracted, and/or absorbed.
• SC.912.P.10.19 Explain that all objects emit and absorb electromagnetic radiation and distinguish between objects that are blackbody radiators and those that are not.
• SC.912.P.10.20 describe the measurable properties of waves and explain the relationships among them and how these properties change when the wave moves from one medium to another.
• SC.912.P.10.22 Construct ray diagrams and use thin lens and mirror equations to locate the images formed by lenses and mirrors
• SC.912.P.12.7 Recognize that nothing travels faster than the speed of light in vacuum which is the same for all observers no matter how they or the light source are moving.
