Help your students build real understanding of water purity testing lab through ninety questions that move from basic recognition to genuine reasoning about how the Earth works.
Sample questions include "What instrument is commonly used to measure pH in water?", "Turbidity can be caused by which of the following?", and "Which of the following is NOT a standard method for testing water purity?"
All three worksheets cover the same topic in different question styles. That means you can use one as a pretest, another for practice or homework, and the third as a follow up quiz, without students ever seeing the same question twice.
This set is part of a NGSS aligned earth science unit. The unit also covers Environmental Monitoring, Human Impact on Ecosystems, Case Study Local Issue, Tools for Monitoring, Impact Mitigation Strategies, and Conservation Planning, all in the same three worksheet format, so your classroom routine stays familiar while the topic changes.
Suitable for Grade 6-8 earth science classes, and for review at any point in the school year. This set is aligned to NGSS standard MS-ESS3-3.
