Where Is the Matter?

Track down the missing matter in this fifth-grade science worksheet! Learners will read about a student performing an experiment in which an amount of mass seems to disappear when a chemical reaction is performed in an open container, but the mass stays the same when the reaction occurs in a closed container. Students can use the text and accompanying tables to help them answer questions and explain where the mass in the first reaction went. 

This worksheet is perfect for students building vital science skills and learning about the physical sciences. Learners will need to use their critical thinking and data interpretation skills to show that mass is always conserved, even when it seems to disappear.
