Measure and graph quantities to provide evidence that regardless of the type of change that occurs when heating, cooling, or mixing substances, the total weight of matter is conserved. 5-PS1-2
Clarification Statement: Examples of reactions or changes could include phase changes, dissolving, and mixing that form new substances.
Assessment Boundary: Assessment does not include distinguishing mass and weight.
Using Mathematics and Computational Thinking
Mathematical and computational thinking at the 3–5 level builds on K–2 experiences and progresses to extending quantitative measurements to a variety of physical properties and using computation and mathematics to analyze data and compare alternative design solutions.
Measure and graph quantities such as weight to address scientific and engineering questions and problems. (5-PS1-2)
Structure and Properties of Matter
The amount (weight) of matter is conserved when it changes form, even in transitions in which it seems to vanish. (5-PS1-2)
No matter what reaction or change in properties occurs, the total weight of the substances does not change. (Boundary: Mass and weight are not distinguished at this grade level.) (5-PS1-2)
Scale, Proportion, and Quantity
Standard units are used to measure and describe physical quantities such as weight, time, temperature, and volume. (5-PS1-2)
Scientific Knowledge Assumes an Order and Consistency in Natural Systems
Science assumes consistent patterns in natural systems. (5-PS1-2)

This article shows how formative assessment probes can be embedded into a sequence of 5E Instructional Model lessons for grade 5 students focusing on the conservation of matter. In the lessons, students make their thinking visibl ...
"Nails in a Jar" is a formative assessment from Page Keeley's Uncovering Student Ideas in Science, Volume 4. Studens are asked whether the mass of a sealed jar of wet nails would change as the nails rusted. The probe elic ...
Students investigate and describe multiple indicators of both physical and chemical changes over a 10 day unit. The learning opportunities students were provided specifically addressed misconceptions about the reversibility of changes and the co ...
In this probe, teachers are trying to elicit student ideas about conservation of matter in a closed system. Students read through the scenario and then choose the statement that best describes the matter in the jar and explain their thinkin ...
Students are presented with 4 possibilities about what happens to the weight of a cookie when it is broken. They are asked to choose one and then explain their thinking. The intent of this formative assessment probe is to determine student ...

This resource is for teachers who want to help their students learn about the small particle model of matter—that is, the idea that (1) all matter is made of particles that are too small to see, even with a microscope; (2) there is empty space betwee...
