Draw conclusions drawn and non-existent or tentative or not why independent variable from data compared with unrelated to data expressed clearly affects dependent variable predictions Advance Preparation Post the Data Table developed in Lesson 6 Photo copy the worksheet Conduct the experiment yourself Determine the spaces where students will be able to test their wind-ups. The space will probably need to be larger than a typical classroom; possibilities are a hallway, lunchroom or gym. Materials Wind-ups made in Lesson 4, using plastic lids as wheels Wind-ups made in Lesson 6, using paper plates as wheels Materials to repair or make new wind-ups (same as lessons 4 & 6) Procedure Review of the plan for an experiment (Whole class 10 min.). Review the plan for collecting data about – the distance traveled by two kinds of wind-ups: those with big wheels and others with small wheels. Point out that a wind-up might go all the way across a classroom, and that there could be furniture in the way. Ask: What would be a good place to test our wind-ups?
