States of Matter and Weight (or Mass) Investigation Kit

In this investigation, students figure out what happens to the weight of a substance when it changes from a solid to a liquid or a liquid to a solid. The States of Matter and Weight kit includes all the materials students will need to design and carry out an investigation in the 5th-grade science book (NGSS Edition).  Each kit contains enough materials for six groups of students.  ​ Materials:  Test Tubes for Lard Test Tubes for Wax Pellets Test Tubes for Water Test Tubes for Chocolate Chips Chocolate Chips Wax pellets Lard Glass Beaker Test Tube Clamps Scale Test Tube Rack Holder Test Tube Stands Hot Water Bath Alignment with Academic Standards for Science  Source  Code  Performance Expectation  NGSS  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.    Core Idea(s)  EPS2: Physical and chemical change in matter  EPS1: Structure and Properties of Matter  Practices  SEP1: Asking questions and defining problems   SEP3: Planning and carrying out investigations  SEP4: Analyzing and interpreting data  SEP5: Using mathematics and computational thinking   SEP7: Engaging in argument from evidence  SEP8: Obtaining, evaluating, and communicating information   Crosscutting Concepts  CC3: Scale, proportion, and quantity  CC5: Energy and matter  Note: The product images shown may be for illustration purposes only and may not be an exact representation of the product.
