3-PS2-1 is part of the Next Generation Science Standards. Motion Lab practices it. Standards vary by state, so check with your kid’s teacher for the exact match.

The game

Motion Lab Balanced forces, motion patterns, speed, magnets and static3rd grade

Motion Lab: On a lab bench, force arrows push carts and racers. Kids tell balanced from unbalanced forces, predict which way things move, spot motion patterns, compare speeds, and explore magnets and static electricity.

Practice it at home

Have a gentle tug-of-war: when both sides pull the same, nothing moves. That's balanced forces.
