Grade 3: Forces and Interactions (3-PS2-2)


  • Grade: 3
  • Content Area: Physical Science: Forces and Interactions
  • NGSS Standard: 3-PS2-2


This unit combines science and engineering through a series of lessons on forces and interactions. Students begin with observing forces on the playground, then students complete an investigation where they identify a pattern that can be used to predict future motion. The culminating project consists of students planning and conducting their own investigation. Students keep science journals where they record key terms, make predictions, complete data tables, and draw models.
