1 – 3 of 3 Classroom Resources

  • Density, Identifying an Unknown, Measurements, Scientific Notation, Error Analysis | Middle School

    Lab: A Chemistry Calculation Challenge

    Students will apply their knowledge to solve four challenging chemistry-based calculation problems involving mass, volume, density, and number of molecules.

  • Accuracy, Measurements, Significant Figures, Accuracy, Error Analysis, Error Analysis | Middle School, High School

    Lab: Accuracy, Precision, and Error in Measurements

    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.

  • Density, Accuracy, Measurements, Significant Figures, Accuracy, Error Analysis, Error Analysis | Middle School, High School

    Lab: Significant Figures and Lab Data

    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.
