Classroom Resources: Quantitative Chemistry

1 – 3 of 3 Classroom Resources

• 

  Measurements, Error Analysis, Scientific Notation, Density, Identifying an Unknown | 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.

• 

  Measurements, Error Analysis, Accuracy, Accuracy, Significant Figures, 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.

• 

  Significant Figures, Measurements, Accuracy, Density, 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.
