• collecting and analyzing data demonstrating how electromagnetic forces can be attractive or repulsive and can vary in strength

     

    • developing and using a model to predict how forces act on objects at a distance.
     
    • using non-algebraic mathematics and computational thinking to explain Newton's laws of motion
    • constructing a model that shows the cycling of matter and flow of energy in the atmosphere, hydrosphere, and geosphere.
     
     
     
    • constructing an explanation to demonstrate the relationship between major cell structures and cell functions (plant and animal).
    • developing and use a model to explain how cells, tissues, and organ systems maintain life
     
    • constructing an explanation for how some plant cells convert light energy into food energy.
