Classroom Resources: Quantitative Chemistry
1 – 3 of 3 Classroom Resources
Accuracy, Measurements, Significant Figures, Accuracy, Error Analysis, Error Analysis | Middle School, High School
In this lab, students make measurements of length and width using four measuring tools. They will measure the same object using measuring sticks of different precision. They will observe that the exactness of a measurement is limited by the precision of the measuring instrument.
Accuracy, Measurements, Significant Figures, SI Units | Middle School, High School
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.
Density, Accuracy, Measurements, Significant Figures, Accuracy, Error Analysis, Error Analysis | Middle School, High School
In this lesson, students will use laboratory equipment of different precision to collect data for several different metals, and then use the data to calculate the density of each. They will then compare their calculated densities to accepted values and determine the combination of equipment that leads to the most accurate calculation of density.
