5-PS1 Matter and Its Interactions

• 5-PS1-1
  Develop a model to describe that matter is made of particles too small to be seen.
• 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.
• 5-PS1-3
  Make observations and measurements to identify materials based on their properties.
• 5-PS1-4
  Conduct an investigation to determine whether the mixing of two or more substances results in new substances.
