September, October, and November Standards Focus

These autumn month have us venturing into the world of Motion and Forces!  For example, we are studying Newton’s Law’s of Motion, different types of forces, how to calculate acceleration and forces and using our new found knowledge to design and build in a few awesome Engineering Design Challenges!  It’s going to be a “moving” experience for everyone!

Our NGSS this season:

“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)”

“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)”

“All positions of objects and the directions of forces and motions must be described in an arbitrarily chosen reference frame and arbitrarily chosen units of size. In order to share information with other people, these choices must also be shared. (MSPS2-2)”

“Gravitational forces are always attractive. There is a gravitational force between any two masses, but it is very small except when one or both of the objects have large mass—e.g., Earth and the sun. (MS-PS2-4)”
