Today we imagined we were geologists called to an earthquake disaster site to analyze rock samples. We measured each rock taken from the site, to learn the width, length, and volume of each one. Scientists could use this data to draw conclusions about the nature of the earthquake.
We used a ruler to measure the length and width of our rock, a scale to measure the mass, and a large measuring cup with water to measure the volume. Afterward, we traded rocks and took the measurements of a different one. We graphed the results while discussing the importance of collecting careful and precise data in science, which allows scientists to form correct conclusions.
