9730469 Sadler DESIGNS is a one year, middle school, physical science and technology course. It is based upon engineering design projects previously developed and tested. "Design-under-constraint" challenges, in which students creatively optimize the functioning of existing devices and processes, are alternatives to traditional and discovery-based experiments. The challenges have been found to significantly change students' science process skills and change their preconceptions. The course addresses the physical science content standards of the science standards through challenges in the construction of batteries, bridges, electromagnets, solar heating and a gravity car. Each challenge begins with student construction of a standard device. The students are challenged to optimize the performance of a variable that has a large range. The construction takes little time and the outcome is tested publicly. Students are asked to predict results of trials and explain the outcomes. Teachers are involved in the development and testing of the materials. The materials are distributed commercially.

小行星9730469 物理科学与技术课程是一门为期一年的中学物理科学与技术课程。 它基于之前开发和测试的工程设计项目。 “约束下的设计”挑战，学生创造性地优化现有设备和流程的功能，是传统和基于发现的实验的替代方案。 研究发现，这些挑战会显着改变学生的科学过程技能并改变他们的先入为主的观念。 该课程通过电池，桥梁，电磁铁，太阳能加热和重力车的建造挑战来解决科学标准的物理科学内容标准。 每个挑战都从学生构建标准设备开始。 学生们面临的挑战是优化一个变量的性能，具有很大的范围。 建设需要很少的时间，结果是公开测试。 要求学生预测试验结果并解释结果。 教师参与编写和测试教材。 这些材料是商业性分发的。
