Bring hands-on Kindergarten STEM activities to life with easy, low-prep engineering challenges.

What’s Included

⭐ 6 Big Class Projects

• Our Tallest Tower

• The Big Bridge

• The Great Marble Race

• Our Class Garden

• The Weather Station

• Invention Convention

⚡ 12 Quick Builds

• Cup Stack Race

• Paper Chain Bridge

• Shape Sort

• Roll and Measure

• Float or Sink

• Magnet Hunt

• Seed Watch

• Nest Test

• Umbrella Test

• Ice Watch

• Carry the Load

• Loud and Quiet

Each class project uses four short sessions.

Each quick build takes approximately 20 minutes.

Every project includes a child-friendly picture page.

The six major projects are extended, project-based versions of each unit's capstone challenge from the Kindergarten STEM Curriculum. The twelve mini-projects are new and stand alone.

How It Works in the Classroom

Use these Kindergarten STEM activities throughout the school year.

• Complete one Big Build at the end of each unit.

• Use quick builds whenever you have a spare twenty minutes.

• Let pairs build individual parts of larger class projects.

• Combine the parts into one shared class creation.

• Use simple classroom materials you already have.

• Follow the Ask → Imagine → Build → Share structure.

• Encourage children to test, measure, observe, and improve.

The resource is designed around short, manageable sessions rather than one long project.

Standards & Learning Goals

These activities support foundational STEM and engineering learning through hands-on experiences.

Students practice:

• Asking questions about real-world problems

• Planning and drawing simple designs

• Building with everyday materials

• Testing ideas and observing results

• Measuring with cubes, counts, seconds, and minutes

• Comparing outcomes

• Making improvements after testing

• Working collaboratively with classmates

• Communicating what they built and discovered

Examples include measuring tower height, counting cars crossing a bridge, and tracking weather observations.
