Draw conclusions from your collected data, and include these conclusions in a written summary report of the investigation. These conclusions, as part of the report, should be written by each student. Post-Laboratory Phase: Through participation in the investigation just described and follow-up discussion, and by consulting references, the students learn that a solid displaces a volume of liquid equal to its own volume. ’’ The teacher follows up the report of the investigation by asking students to develop inquiries from these experiences and to include their inquiries and responses to them as an appendage to their final written report.

Credit slips are also used to record ‘‘answers’’ or investigation tips found by students in responses to inquiries generated during current ongoing investigations. Thus students receive credit for participating in all aspects of each board’s development. In fact, any student or teacher may add appropriate materials related to instruction to either board. Discovery Resources An even more important feature of the inquiry/discovery classroom, however, is the ‘‘resource center,’’ where basic science references, journals, and other print materials, including items from the Internet, are available to encourage further independent discoveries.

Use mathematics in all aspects of scientific inquiry. For Grades 9–12 • Identify questions and concepts that guide scientific investigations. • Design and conduct scientific investigations. • Use technology and mathematics to improve investigations and communications. • Formulate and revise scientific explanations and models using logic and evidence. • Recognize and analyze alternative explanations and models. • Communicate and defend a scientific argument. Necessary Classroom Tools and Resources There are forms of support that, if considered in planning for instruction, will facilitate student inquiry/discovery.
