Big Ideas
  • Forces such as pushes and pulls can change the position and motion of objects.
  • Hands-on investigations help us understand how and why objects move when forces are applied.
Essential Questions
  • How can you change how something moves or where it is by pushing or pulling it?
  • What happens to objects like swings, balls, or wagons when you apply different types of pushes and pulls?
  • How can you design an experiment to test the effects of pushes and pulls?
  • Why is it important to use investigations to observe how motion and position change?
  • How can you explain your observations about how objects move due to pushes and pulls?
