NGSS Grade 5 Measure Matter Physical and Chemical Changes 5-PS-1-2
Students measure and graph mass/weight in order to gather evidence to make a claim that regardless of the type of physical change that occurs, matter is not created or destroyed and mass/weight is conserved.
Activity 1: Physical Change. Students measure and graph substances before and after a chemical change in a closed system to gather evidence to make a claim about the Law of Conservation of Matter/Mass.
Activity 2: Chemical Change. Students measure and graph substances before and after a chemical change to gather evidence to and make a claim about the Law of Conservation of Matter/Mass.
Activity 3: Change Challenge. Students are then presented with an extra challenge to list examples of different types of changes that support the Law of Conservation of Matter/Mass. They are expected to present their physical or chemical change example with evidence as photograph, drawing, demonstration or video.
Included: Background information for teachers, teaching procedure, sample answer sheets, rubrics for scoring student work, student recording pages, Science Notes, Poster for Conservation of Mass, and photos of results.
5-PS1-2 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. (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.]
