*I can develop a model to describe that matter is made of particles too small to be seen. (5-PS1-1)
*I can 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)
*I can make observations and measurements to identify materials based on their properties. (5PS1-3)
*I can conduct an investigation to determine whether the mixing of two or more substances results in new substances. (5PS1-4)
