Plan and conduct an investigation to provide evidence of the effects of balanced and unbalanced forces on the motion of an object. ||Next Generation Science Standards||Grade 3||Physical Science||Motion and Stability: Forces and Interactions |||Make observations and/or measurements of an object’s motion to provide evidence that a pattern can be used to predict future motion. [Examples: a child swinging in a swing, a ball rolling back and forth in a bowl, and two children on a see-saw.] “||Next Generation Science Standards||Grade 3||Physical Science||Motion and Stability: Forces and Interactions |||Use evidence to construct an explanation relating the speed of an object to the energy of that object. ||Next Generation Science Standards||Grade 4||Physical Science||Energy |||Support an argument that the gravitational force exerted by Earth on objects is directed down.||Next Generation Science Standards||Grade 5||Physical Science||Motion and Stability: Forces and Interactions|||Plan an investigation to provide evidence that the change in an object’s motion depends on the sum of the forces on the object & the mass of the object.||Next Generation Science Standards||Middle School||Physical Science||Motion and Stability: Forces and Interactions |||Construct, use, & present arguments to support the claim that when the motion energy of an object changes, energy is transferred to or from the object.||Next Generation Science Standards||Middle School||Physical Science||Energy
