This Concept Map, created with IHMC CmapTools, has information related to: Bocce Anyone, 2. Bring to mind relevant prior learning. Lead a discussion about what students think they already know about force and motion, ramps and balls. Have students write down their ideas, including drawings. Through discussion, students will voice their preconceptions about force and motion, 7. Show students how to categorize (chunk) related information. Ask students to to develop some ideas about how they might answer the mass question posed above. Guided practice: Guide groups to explore the mass changes. Students will design experiments to test their ideas about force and motion, 8. Check for understanding. Have groups share observations from experiments. Ask students to draw and explain current understandings about mass changes. Ask students to compare observations to prior conceptions. Did their ideas change? Students will make claims about force and motion based on evidence they collect through experiments, 6. Check for understanding. Have groups share observations from experiments. Ask students to draw and explain current understandings about ramp changes. Ask students to compare observations to prior conceptions. Did their ideas change? Students will make claims about force and motion based on evidence they collect through experiments, 3. Point out important information. Provide a copy of the story to the students. Remind students of important questions - can ramp be tilted to make a ball roll different distances? If balls are same size but different masses, will they travel different distances? Through discussion, students will voice their preconceptions about force and motion, If more than one force acts on an object along a straight line, the forces will reinforce or cancel one another depending on their direction and magnitude. Unbalanced forces will cause changes in the speed or direction of an object's motion Through exploration with materials students will observe effects of force and motion Grade 5: PO 4. Demonstrate effects of variables on an object’s motion (e.g., incline angle, friction, applied forces)., 9. Closure: Provide for repetition of learning. Restate important principles discovered several times in different ways by reading evidence and claims statements during presentation of information (STM). Leave evidence and claims statements up around room (LTM) for future classes. Students will make claims about force and motion based on evidence they collect through experiments, 1. Gain the students' attention. Read "Bocce, Anyone?" , p. 137-138 Everyday Science Mysteries (2008).Konicek-Moran, R. NSTA Press. It poses the questions (in simpler terms): When playing bocce with a disabled friend, a. Could a ramp be used to roll bocce balls different distances? b. If the bocce balls had different masses, would it make a difference? Through discussion, students will voice their preconceptions about force and motion, Arizona Strand 5: Concept 2: Motion and Forces Understand the relationship between force and motion. Students will design experiments to test their ideas about force and motion, 5. Show students how to categorize (chunk) related information. Ask students to develop some ideas about how they might answer the ramp question posed above. Guided practice: Guide groups to explore the ramp changes. Students will design experiments to test their ideas about force and motion, An object that is not being subjected to a force will continue to move at a constant speed and in a straight line Through exploration with materials students will observe effects of force and motion Grade 5: PO 4. Demonstrate effects of variables on an object’s motion (e.g., incline angle, friction, applied forces)., 4. Present information in an organized manner. Allow students to explore with materials. Stop exploration and have a discussion about terms we might all use to be sure we are understanding each other. Introduce some vocabulary: ramp, mass force, inertia, friction, etc. Through exploration with materials students will observe effects of force and motion Grade 5: PO 4. Demonstrate effects of variables on an object’s motion (e.g., incline angle, friction, applied forces).
