http://nhanley.edublogs.org Fifth Grade AG Module: Motion and Design Wed, 13 Feb 2008 17:41:48 +0000 http://backend.userland.com/rss092 en In this lab, the students had to propel their standard cars with rubber bands. Each group manipulated rubber bands in the following ways: * Stretch the rubber band across to the opposite axle. * Wind the rubber band in opposite directions. * Attach the rubber band under, the over the axle. Some of the students' ... http://nhanley.edublogs.org/2008/02/12/211-examining-the-effect-of-rubber-bands-on-cars/                                                                          Lab 5: Observations  For this lab, the students needed to use their knowledge of what made their vehicle move fast and slow from their last lesson to design a fast-moving car of their own. What made our vehicle move slow: Heavy Load No Slope String got stuck Not enough washers What made our vechile move quickly: Less ... http://nhanley.edublogs.org/2008/02/06/2-6-testing-vehicle-loads/ In today's lab, the students set up experiments to examine the effect mass has on an object while maintaining a constant force. The students added up to two different wooden blocks to their standard vehicles to investigate the effects of a load on motion. During the lab, the students measured ... http://nhanley.edublogs.org/2008/02/06/2-4-examining-the-effects-of-mass-on-an-object/ Today, the students disassembled their own car designs and built a standard model. Each team of 3-6 students received 16 small weights, a bookend, clips and string. Their goal was to determine the effect adding additional weight would have on speed and distance of their cars.  Predictions: * Adding extra weight will ... http://nhanley.edublogs.org/2008/02/01/131-examining-the-effect-of-weight-on-motion/ January 30, 2008  Objective:To represent a side and top view of the vehicle.    What we learned: Converting scale is a lot easier than it looks.        Challenges we faced:       *Our biggest challenge was drawing and measuring the vehicle and also having to convert the measurements to fit the paper!  http://nhanley.edublogs.org/2008/02/01/130-drawing-the-top-and-side-view-of-our-vehicles/ This blog will be devoted to the fifth grade students' developing understanding of motion and design throughout the next nine weeks. Our first lesson introduced students to the physics of motion and elements of design. The students recorded what they already knew and what they wanted to learn about both concepts:  What ... http://nhanley.edublogs.org/2008/01/31/introduction-129/
