Forces and Motion Newtons Laws Activity NGSS MS-PS2-1 & 2 Google Ready


SKU: 7303862 Category: Tags: , ,


This activity makes learning about Newton’s 3rd Law, Balanced/Unbalanced Forces, Friction, and energy fun! It’s easy prep, rigorous and engaging! The only materials you need are one 12-inch balloon per group (buy extra because they can break), one straw per group, one piece/roll of tape per group, 1.5-2 meters of string per group and I recommend getting one balloon pump per group.

This activity is approximately 75 minutes from start to finish.

I put helpful tips next to most of the slides and the key on the last slides.

You get an 11 slide Google Slideshow that includes the following:

-Teacher notes, standards and materials list

-Lab activity with questions and modeling/diagram


-Student examples

What students do:

-They observe the teacher releasing an inflated and are asked why is flies.

-Class discussion of Newton’s 3rd Law

-Students make a hypothesis as to whether a larger blown up balloon will have a greater velocity than a smaller one.

-Students collect data and calculate velocity of different size balloons.

-Students answer questions.

-Class discussion of how Newton’s 3rd Law, Energy and other forces apply to their balloon rocket.

-Students make a model of their balloon demonstrating how the vocabulary applies to the balloon rocket.

Concepts Included:

-Newton’s 3rd Law

-Balanced and Unbalanced Forces


-Sliding friction

-Fluid Friction

-Potential Energy

-Kinetic Energy

Interdisciplinary Core Ideas

PS2.A:  Forces and Motion

The motion of an object is determined by the sum of the forces acting on it; if the total force on the object is not zero, its motion will change. The greater the mass of the object, the greater the force needed to achieve the same change in motion. For any given object, a larger force causes a larger change in motion. (MS-PS2-2)

For any pair of interacting objects, the force exerted by the first object on the second object is equal in strength to the force that the second object exerts on the first, but in the opposite direction (Newton’s third law). (MS-PS2-1)

PS3.A:  Definitions of Energy

Motion energy is properly called kinetic energy; it is proportional to the mass of the moving object and grows with the square of its speed. (MS-PS3-1) A system of objects may also contain stored (potential) energy, depending on their relative positions. (MS-PS3-2)
