This study focuses on the design of a learning program to introduce complexometric titration as a method for determining water hardness in a high school chemistry laboratory. Students are introduced to the different properties and reactions of hard water in a stepwise manner so that they gain the necessary chemical knowledge and conceptual…

Teaching the acoustic properties of materials is a good way to teach physics concepts, extending them into the technological arena related to materials science. This article describes an innovative approach for teaching sound and acoustics in combination with sound insulating materials in secondary school (15-16-year-old students). Concerning the…

Described is the proposed implementation of Scope, Sequence and Coordination into California and Houston schools. The rationale behind this project is discussed. The curriculum, arranged developmentally, merges different scientific subjects via discipline-bridging themes. (KR)
