How are Waves Refracted? This Question Exploration examines this Essential Question, and helps Ss answer the Index of refraction.
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 a worksheet requiring the use of a protractor. 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 why light rays bend when they enter a medium at an angle
• SWBAT identify factors that affect the speed of light waves, sound waves, and other types of waves
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.10.20 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
