Yearly Tasks • 1 st Year participants • Complete marketing and sponsorship curriculum materials • Create a budget and purchase required components • Complete kart assembly curriculum materials • Collect data during spring test and tune events • Refine setup and acquire track experience • Teams with Prior Experience • Complete marketing and sponsorship curriculum materials • Create a budget and purchase required components • Collect data during fall karting science Saturday events • Redesign previous years kart based on fall events data • Revisit kart assembly curriculum materials during kart rebuild • Collect data during spring test and tune events • Refine new kart setup and acquire track experience • All Participants • Document all steps and prepare presentations for academic challenge • Meet all tech inspection and safety requirements

Important Rules and Regulations • The race chassis selected and certified for the competition is a commercially available “Sprint Kart” chassis. • The approved tire for the series will be manufactured by HOOSIER Racing Tire. • All karts must be equipped with a commercially available front crushable, which is attached to the front bumper to minimize shock in the event of a front impact. • Only Interstate Battery SLA 1155 or SLA 1156 are allowed in the High School Series. • The system may use any combination of battery instantaneous voltage and instantaneous current, as long as this value does not exceed 10 k. W.

Important Rules and Regulations cont. • The Motenergy ME 0708 PMDC brushed DC motor is the spec motor for the high school series. • The Alltrax SPM 48300 or SR 48300 are the only acceptable motor controllers allowed. • High school karts have a minimum weight as raced and including driver and all safety equipment at 420 lbs. • Each team will be provided with an “Energy Efficiently Rating” in the Academic Challenge Summary sheet at the awards ceremony. The ratings will be ordered from least amount of energy to most and assigned a place value. Your placement will be assigned to a point value from 0 to 15. If there is a tie, then Race Placement will be the tie-breaker.

Driver Protective Clothing • Helmet • Driver’s suit must be manufactured for racing. Suit must be constructed of heavy weight, abrasion resistant nylon. • The driver’s suit must cover the ankles and wrists while seated in the kart. Exposed skin will result in a black flag penalty. • To prevent or minimize abrasions, all drivers shall wear gloves of Kevlar, leather or vinyl material. • The driver shall wear approved neck brace, socks covering the ankles, and full coverage sturdy shoes, boots or racing shoes. • The driver shall wear an approved rib protector under his or her suit. • Long hair ‐ No hair may be outside of the helmet. A head sock or other method must be used to restrain hair. This is a black flag offense.

Data Collection • Physics Box Run kart at track or during Karting Activity. Download Data from Physics Box Data Analysis for design and setup improvements Data collection allows teams to explore all aspects of go kart racing, including: • How is kart setup influence kart performance? • How does changing kart dynamic affect kart response? • How does driver performance improve as experience increases? • What affect does kart setup and driver experience affect battery performance and energy efficiency?

Data Collection Activities Left hand turns resulting in positive (+) acceleration for approximately 2 seconds Right hand turns resulting in positive ( ) acceleration for approximately 4 seconds A B

Karting Activities • Learn – Learn the science content behind specific motorsports applications i. e. Gears and Gear Ratios • Practice – Classroom curriculum provides immediate feedback on understanding and application • Collect Data – Go Kart specific activities provide hands-on application, Physics Box allows for immediate data collection and analysis

Balance and Center of Mass Content studied science class relates directly to motorsports and ev. Grand Prix Karting Science Curriculum in-turn reinforces science content and provides a context for learning within the classroom.
