♦ 2-PS1-1. Plan and conduct an investigation to describe and classify different kinds of materials by their observable properties.
◊ 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.
º 5-PS1-3. Make observations and measurements to identify materials based on their properties.
