Slingshot Dart Shooter

Projectile shooters are always fun to build, but one can make only so many catapults before the novelty wears off. The slingshot dart shooter mixes it up with elements from my Slingshot Rocket project and regular Slingshot, but in the classic 'Y' slingshot shape. 

Lesson Plan:
Difficulty: 2/5
Prep: 2/5
Setup: 2/5
Cleanup: 1/5

As always, begin by demonstrating how the project works. Next, walk the students through the construction process, explaining key design elements along the way. Notable design features to explain include: trusses used to reinforce the Y shape; crossing the rubberband; and adding weight to the front of the dart.

CAUTION! This project can be dangerous! Tell your students that they are never allowed to point the slingshot at someone else, even if it is unloaded. Inform your students of a zero-tolerance policy: if they intentionally shoot someone, they will have their slingshot revoked until the end of class.

Learning Objective:
  • Students will understand the significance of trusses and how to effectively implement them to strengthen the design of their slingshot.
  • Students will experientially understand how stored energy can be converted to kinetic energy through the use of the slingshot dart shooter.
  • Students will gain insight into the outcomes of different trajectories. Through trial and error, students will learn how to exploit trajectories to achieve greater launch distances

Cute! It looks like fun! :)

Everyone please check your local laws first! Slingshots are illegal to manufacture or possess in many places.
