written by Mary Hebrank
This inquiry-based curricular unit introduces middle school students to the concept of density through five hands-on experiments. In Activity 1, they handle five identical boxes, each filled with a material of differing density, to get a feel for the relationship among mass, volume, and density. Next, they devise methods to figure out the density of solid objects by using water displacement. Finally, they use their knowledge to determine how to calculate density without being given a formula.

Activities come with learning objectives, student guides, teacher content support, and ideas for assessment. All are aligned to national math and science standards.

Teach Engineering is an NSF-funded Pathway developed to provide high-quality experiential learning materials for K-12 classrooms.

### AAAS Benchmark Alignments (2008 Version)

#### 1. The Nature of Science

1B. Scientific Inquiry
• 6-8: 1B/M1b. Scientific investigations usually involve the collection of relevant data, the use of logical reasoning, and the application of imagination in devising hypotheses and explanations to make sense of the collected data.

#### 4. The Physical Setting

4D. The Structure of Matter
• 6-8: 4D/M10. A substance has characteristic properties such as density, a boiling point, and solubility, all of which are independent of the amount of the substance and can be used to identify it.

#### 12. Habits of Mind

12B. Computation and Estimation
• 6-8: 12B/M3. Calculate the circumferences and areas of rectangles, triangles, and circles, and the volumes of rectangular solids.
• 9-12: 12B/H3. Make up and write out simple algorithms for solving real-world problems that take several steps.
