Grade 6 · Ages 11-12

Sixth graders can run a controlled test, measure the outcome, and defend the result. These kits give them a vehicle (literally) to use for their investigations.

Rubber Band Helicopters
01 Energy conversion · flight

Rubber Band Helicopters

  • Simple and quick to build. Challenging and fun to optimize.
  • Number of rubber bands, amount of energy stored, flying technique, and the paper cutout all affect flight time.
  • Shows energy conversion directly: stored elastic energy becomes rotation, then lift.
Why it fits sixth grade
  • By 6th grade, students can push the limits of this project and make it fly higher than the classroom roof.
  • Optimizing the helicopter is still challenging enough to keep them engaged for an entire class.
  • Kids can master the flying technique, so the nuances of the paper cutout's shape and size are best explored at this age.

02 Drivetrains · vehicles

Rubber Band Cars

  • A chain of rubber bands drives the axle directly, creating a super-speedy vehicle.
  • The number of rubber bands, how they are wrapped around the frame, and the number of times they're wound around the axle affect the distance traveled.
  • All the cars drive straight, so distance and speed make for clear optimization targets.
Why it fits sixth grade
  • A more challenging and robust build for lower middle schoolers.
  • The kit's unique rubber band system allows students to optimize for speed or distance. Both are independently measurable.
  • Builds on the science and engineering concepts from the rubber band helicopter, but this time for driving a vehicle.

Wonky Robot Kit
03 Simple circuits · robotics

Wonky Robot Kit

  • Students build a motorized robot-styled machine using special high-power motors.
  • Combine different wheel attachments to change the driving pattern.
  • See frequency and patterns in a delightful robot-styled design.
Why it fits sixth grade
  • Jumper-style wire connectors allow students to independently create their own circuit, as well as experiment with reversing the current.
  • Students have probably never done a project like this, making engagement an easy win for teachers.
  • 6th graders can tackle the more challenging investigations, such as finding a combination of wheels that can overcome various obstacles.
