Accuracy, Measurements, Significant Figures, SI Units  Middle School, High School
Activity: Simulation Activity: 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.

Lesson Plan: Chemical Measurement Unit Plan
The AACT High School Classroom Resource library has everything you need to put together a unit plan for your classroom: lessons, activities, labs, projects, videos, simulations, and animations. We constructed a unit plan for introducing concepts student need to collect and use chemical measurements: Percent Composition, Metric Units, Accuracy and Precision, Percent Error, Density, Scientific Notation, Significant Figures, and Unit Conversion. This unit is designed to be used at beginning of the school year and modified based on student math abilities.
