Physical Science

• Develops a model to describe that matter is made of particles too small to be seen. PS1-1 

• Measures and graphs 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. PS1-2 

• Makes observations and measurements to identify materials based on their properties. PS1-3 

• Conducts an investigation to determine whether the mixing of two or more substances results in new substances. PS1-4 

• Uses models to describe the energy in animals’ food (used for body repair, growth, motion, and to maintain body warmth) was once energy from the sun. PS3-1 

Life Science

• Develops a model to describe the movement of matter among plants, animals, decomposers, and the environment. LS2-1 

Engineering

• Defines a simple design problem reflecting a need or a want that includes specified criteria for success and constraints on materials, time, or cost. ETS1-1 

• Generates and compare multiple possible solutions to a problem based on how well each is likely to meet the criteria and constraints of the problem. ETS1-2 

• Plans and carries out fair tests in which variables are controlled and failure points are considered to identify aspects of a model or prototype that can be improved. ETS1-3
