PHYSICAL SCIENCE-During this module, students observe the properties of five household substances--alum, salt, cornstarch, baking soda, and talcum powder--and investigate changes in the properties of those substances as they react with water, vinegar, red cabbage juice, and iodine. Because students often think of chemical reactions as "magic," this module helps students build an understanding that chemicals undergo predictable changes that can be controlled. The students use the processes of scientific inquiry, including fair testing (controlling variables), collecting and recording data, using evidence to build explanations, and communicating their results, to investigate changes in the properties of simple household chemicals.

BSCS Science Tracks includes a comprehensive Student Guide and resource book at every level, 1-5. The Student Guide is not a "read-about-science" book; rather, it serves as a guide to help students learn to do the following things.

  • Conduct scientific inquiries within a collaborative team and on their own
  • Become more responsible for their own learning
  • Manage the hands-on activities themselves
  • Structure collaborative learning tasks
  • Develop science and technology concepts and skills
  • Reflect on their learning and assess their own conceptual and skill development
  • Conduct independent inquiries related to questions or topics of personal interest
  • Develop skills for reading in the content areas
  • Follow and interpret directions

In addition, the Student Guides reinforce components of basic literacy, including shared reading and writing, guided reading and writing, continuous assessment, skills instruction, reading procedural text, listening and speaking skills, journal writing, record keeping, hints and reminders, reading and writing in a social context, and reading and writing in a content area.
