How Can We Change An Object's Motion?

How Can We Change An Object's Motion?

How Can We Change an Object’s Motion? is part of Smithsonian Science for the Classroom, a new curriculum series by the Smithsonian Science Education Center. It is aligned to a group of kindergarten standards. It has a focus on physical science with a secondary focus on engineering. In this module, students:

  • Develop models based on observations to explain how pushes and pulls change an object’s motion. 
  • Carry out an investigation to evaluate the effectiveness of different objects to push a ball into a goal. 
  • Carry out an investigation to compare the effect of collisions with different materials on an object’s motion.
  • Design and test a wall for a hockey game that keeps the ball in the game space and allows the ball to score a goal after a collision with the side wall.
  • Develop and test a model to figure out what caused a ball to change its direction of motion inside a mini golf feature.
