In this video, Dr. Jeff Viniker teaches students the science behind balanced and unbalanced forces. This video combines work and play. You’ll feel like that you’re learning how to play a tug of war game. But in reality, you will be learning the effect of balanced and unbalanced forces on motion. If both the opponents apply equal and opposite amounts of force, the resultant force will be zero and the flag will not move. But if one player exerts more force than the other, then not only the flag will move in that player’s direction but the opponent will fall too. Students will find this video both fun and informative at the same time.
This video satisfies the 3-PS2-1 requirement for third-grade science proficiency.
Students who demonstrate understanding can:
3-PS2-1. Plan and conduct an investigation to provide evidence of the effects of balanced and unbalanced forces on the motion of an object.
