Description

Perfect for high school Chemistry students, this lab introduces the comparison between accuracy and precision in scientific measurements. This is a fun chemistry activity for the first week of school when students are just reviewing how to make accurate measurements and can be a good introduction to significant digits.

NOTE: This lab is also part of my Full Chemistry Curriculum.

This accuracy and precision lab involves three parts:

• Students drop markers on a target to determine the accuracy and precision of their marks
• Students draw circles estimated to be 5 cm, then measure the accuracy and precision of their drawings
• Students measure their height with a ruler and meter stick or tape measure then use the percent error formula to analyze their measurements

Included in this resource:

• Teacher instructions and materials list
• Student worksheets (2 pgs)
• Answer key to student worksheet
• Quick check to assess student understanding after activity

Required background knowledge:

• How to make metric measurements
• How to multiply and divide using a calculator
