This lab utilizes ImageJ’s photo analytics to investigate elements of digital photographs. These tools can be used to calculate lengths, areas, volumes and angles. We will use these tools to calculate the volume of a container and estimate the number of pieces of candy that will fit into it. </p><p>In this lab, students will use ImageJ to calculate the volume of a piece of candy and the volume of the container that candy will go in. How many pieces of candy will fit into the container? The winning team of students will receive a prize!</p><p>Assessment</p><p>Pre-Assessment: </p><p> Students should estimate the volume of the container. </p><p> Students should be able to estimate how many pieces of candy will fit into a given container.</p><p>Results/Conclusions: </p><p> Students should be able to calculate the volume of three dimensional figures.</p><p> Students should be able to determine the ratio of volumes of figures with and without ImageJ software.</p><p>Reference(s):</p><p>The RET Program at Appalachian State University – Summer 2013.</p>
