Welcome to STEM learning for Grade 3

Engineering

Building • Testing • Simple machines • Problem solving

Engineering Design Process


Students learn:


Students apply a structured problem-solving process.

  • Defining the problem:
    Identifying goals and constraints.
  • Planning solutions:
    Sketching ideas and selecting materials.
  • Testing and improving:
    Using results to make improvements.

Structures & Materials


Students learn:


Students investigate how materials and shapes affect strength.

  • Load and support:
    Structures must support weight without collapsing.
  • Material properties:
    Strength, flexibility, and durability.
  • Comparing designs:
    Evaluating which structures perform better and why.

Simple Machines & Mechanical Systems


Students learn:


Students explore how simple machines work together.

  • Levers, pulleys, wheels, ramps, gears (intro):
    Machines change force or direction.
  • Mechanical advantage:
    Machines make work easier.

Forces & Motion


Students learn:


Students explore how forces affect movement.

  • Pushes and pulls:
    Forces can start, stop, or change motion.
  • Friction and gravity:
    These forces affect speed and direction.
  • Testing variables:
    Changing one factor at a time.

Engineering in Everyday Life


Students learn:


Engineering improves quality of life.

  • Problem-solving in communities:
    Clean water, transportation, and safety.
  • Sustainable design (intro):
    Designing with care for the environment.
