Error, Accuracy and Precision Lab

Description

Error, Precision and Accuracy Lab Preview

SNAPs Lab Stations Activities require students to use science, math, literacy, problem-solving and engineering skills. They are designed to enhance students’ understanding of scientific concepts and help students apply scientific ideas to the real world. Each station activity promotes skills so to develop students into proficient and competent scientific thinkers.

SNAPs lab activities have five components:
• Science Skills Station to develop science skill proficiency
• Narrative Station to build science literacy
• Assessment Station to evaluate learning and understanding
• Problem-Solving Station to foster engineering design
• Synthesis Station and Project to inspire higher-order learning

The activities at each station in this lab are detailed below.

Error, Accuracy and Precision Lab Stations Activity Learning Objectives
1. Students will be able to calculate statistical (percent) error.
2. Students will be able to analyze the precision and accuracy of measurements with statistical calculations such as mean, range and percent error.
3. Students will be able to compare and contrast accuracy and precision.
4. Students will be able to develop solutions that reduce error and improve the accuracy and precision of measurements.

Science Skills Station
Students will be presented with sets of data at this station. They will calculate mean, range and percent error and determine the significance of the error in the data collected. Students will use this information to analyze the precision and accuracy of the data.

Narrative Station
Students will read a passage about error, what causes error and how to calculate statistical (percent) error. Then students will watch a video about the difference between accuracy and precision and how they are important to reducing error when making measurements.

Assessment Station
At this station, students will answer questions about key terms and ideas relating to error, precision and accuracy. Students must employ lower, mid and higher order thinking skills to answer these questions.

Problem-Solving Station
Students will identify problems that cause error, and thus impact the accuracy and/or precision of a measurement or calculation. Students will analyze the accuracy and precision of measurements, what problems cause measurements to not be accurate or precise and how to fix those problems.

Synthesis Station
Students will compose a CER (claim-evidence-reasoning) report to summarize the lab. Students are provided the claim statement and must support the claim with observations, data and other information gathered in the lab. Students will explain how the evidence supports the claim using scientific reasoning.

Synthesis Project
Students will have a choice of 11 projects. Refer to the SNAPs Lab Stations Best Practices and Setup Guide for directions and suggestions on how to conduct the project.
