Accurate Measurement

精确测量

Description

Take measurements with increasing accuracy and precision using a range of scientific equipment, taking repeat readings when appropriate

Mastery Evidence

✓ Use scientific equipment (scales, thermometers, measuring cylinders, stopwatches) with increasing precision
✓ Explain why repeat readings improve reliability and take at least three readings
✓ Identify and deal with anomalous results (measurements that don't fit the pattern)

Assessment Prompt

Can your child measure things precisely during experiments, know when to take repeat readings for reliability, and spot when a measurement seems wrong?
