Looking Back Looking Ahead
Plan and conduct an investigation to compare the effects of different strengths or different directions of pushes and pulls on the motion of an object. (K.PS.3) Investigate transportation systems and devices that operate on or in land, water, air and space and recognize the forces (lift, drag, friction, thrust and gravity) that affect their motion.
