Mathematics and science are natural partners. One of many examples of this partnership occurs when scientific observations are made, thus providing data that can be used for mathematical modeling. Developing mathematical relationships elucidates such scientific principles. This activity describes a data-collection activity in which students employ the scientific method to explore the relationship between the number of spaghetti strands making a "bridge" and the weight that the bridge can support. Students will make qualitative predictions about relationships between variables and write linear equations to represent their data. This lesson actively engages students in the collection and analysis of data. The opening demonstration creates a "hook" for students at the beginning of the lesson as well as modeling the method of data collection A bibliography and two activity sheets are included.
