This probe is a great way to determine what students understand about the conservation of mass. The best part is that Page helps you figure out what you shoud do next in your instruction. Great formative assessment.

This probe is an excellent way to find out what student know about conservation of matter. One of the best thing PAge does in her books is include how you would use this probe at many different grade levels. I highly recommend this book. Kathy

Outstanding information can be gained as you administer this probe to your 3rd-6th graders. Possibly 7/8th use for ESL or Special Needs students. Will cover conversation of mass along with view on pebbles/rocks/boulders. I'm never disappointed in the information I gain as an educator on my students' insights and misconceptions.
