Texas Chemistry Standards (TEKS)
C.2.F: The student is expected to collect data and make measurements with accuracy and precision.
C.2.G: The student is expected to express and manipulate chemical quantities using scientific conventions and mathematical procedures, including … significant figures.
C.2.H: The student is expected to organize, analyze, evaluate, make inferences, and predict trends from data.

Lesson Summary:
This guided inquiry lesson enables students to construct their own understanding of how to ensure the accuracy and precision of measurements by recording values to the correct number of significant figures. They also discover how to differentiate between accuracy and precision and how to calculate the percent error of experimental data. Students are able to actively learn the material without lecture or note taking.

Part 1: Significant Figures
• Students investigate how measuring with different rulers can affect the measurement result. They discover that measurements should recorded using all of the certain digits plus one digit that must be guessed.

• Students work through eight task cards which require them to practice recording measurements to the proper number of significant figures.

Part 2: Accuracy and Precision
• Students investigate accuracy and precision by dropping a ball on a target with their eyes closed and opened. They compare these two sets of data and evaluate them for accuracy and precision.

• Students create illustrations of targets showing examples of data that is: 1) accurate, not precise; 2) precise, not accurate; 3) not accurate, not precise; 4) accurate, precise

• Students create and measure lines to generate data. They evaluate the accuracy and precision of this data.

Percent Error
• Students calculate of the percent error of their line data.

• Students work through four task cards which require them to calculate percent error and define accuracy and precision.

Student Study Sheet
Students are provided with a student study sheet summarizing all of the important concepts and vocabulary in this lesson.
