Safety FeaturesWhat do you know about safety features in passenger cars and race cars?
SAFER DrivingTeenage Driving
Since 2001, there have been over 100,000 deaths of 16-24 year olds when young people are driving
Teens have the lowest rate of seatbelt use.
Teens underestimate dangerous situations.
Teens are more likely to follow a car too closely.
Racing
Since 2001, there have been zero deaths in NASCAR’s three National Series.
Fire-retardant clothing, including underwear and gloves (DuPont NOMEX).
Soft wall technology: SAFER Barrier.
Helmets required for over-the-wall pit crew.
HANS (head and neck support) device (DuPont’s Kevlar).
Safety Features
With your team, prepare an explanation of the science behind your assigned safety feature. Include at least one of Newton’s Laws of Motion in your explanation.

Materials for SAFER Egg Car2 sheets of paper, 4 wheels, 2 axles,
1 straw (axle housing), glue, egg
SAFER Egg DesignQuestion: Is it possible to build a car from paper and glue that is strong enough to protect a raw egg during a head-on collision?
Constraints1. Maximum car width: < 6.5 centimeters (including axles and wheels)2. Maximum car length: < 16.5 centimeters3. Minimum car mass without the egg: > 30 grams4. The entire body of the car must be made of paper and glue.5. Design must include 3 safety features of which one must be a seatbelt that can be unfastened.
Reflecting on Safety Features
What new information did you learn about car safety features?Will what you learned make a difference in your behaviors as a driver or passenger? Explain.
