Measurements, SI Units, Significant Figures, Accuracy  Middle School, High School
Simulation: Measuring Volume
In this simulation, students will participate in a 10 question quiz. The quiz questions are each made of two parts, with the first part requiring the student to analyze an image of a graduated cylinder in order to report an accurate measurement. Students must use the correct number of digits based on the markings presented on the cylinder when reporting the measurement. In the second portion of the question the students will determine the uncertainty value of the graduated cylinder, again by analyzing its markings. The simulation is made up of several different sizes of graduated cylinders, each containing unique markings, so students will be challenged to analyze each individually.
