Grade Level: 9th - 12th; Type: Physics/Aerodynamics
Design the perfect arrow. The goals of this project are:
- To study the history and aerodynamics of arrows.
- To calculate an optimal arrow design.
- To invent a new or improved arrow design.
- What are arrows made of?
- How is a basic arrow designed and created?
- What is the average distance an arrow will travel when released from a bow?
- How fast does the average arrow fly?
- What materials work best for making arrows?
- How has arrow-making technology changed over time?
Arrows are among the oldest weapons known to mankind. Early humans fashioned arrows from chiseled stone points tied to lightweight reeds with sinew cord. These were used for hunting and self-defense. Arrow-making technology has changed quite a lot since ancient times. In this project we attempt to design a perfect arrow.
- Computer with Internet access
- Color printer
- Digital camera
- Typical office/hobby/hardware/craft supplies (paper, poster board, glue, etc.)
- Stone, fiberglass or aluminum for the arrow heads.
- Straight, slender stakes of wood, bamboo, reeds or fiberglass for the shafts.
