An Egg-cellent Race Car Designing a fast and safe car
100 points
Crash test Question How do people survive major collisions in fast cars?
Purpose To experience the engineering design process.
To build a sturdy, fast car to safely race down an acceleration ramp.
To protect a raw egg passenger during a collision with a solid barrier.
To explain the science behind a car and its collision into a solid barrier in terms of speed,
slope, acceleration, energy, forces, inertia, mass, momentum, and Newton’s 3 Laws.
Materials For each team:
Provided by teacher:
Cardboard
2 straws
2 2.5 mm x 11 cm wood dowel rods for axles
Construction paper
scissors
rulers
markers
Provided by each group:
1 roll of tape
lids for wheels
Discussion How do people survive major vehicle collisions while in fast cars? Scientists and engineers
apply the laws of physics to reduce damage to both cars and passengers. During this project,
you will work in teams to use the engineering process to create a sturdy, fast, & safe car to
protect a raw egg a collision. This project will help you reinforce the concepts from class and
elaborate on some of the “Eggcellent” safety devices in a car!

Designing an Egg-cellent Race Car
The Rules Failure to do follow these rules will reduce your grade and eliminate you from the contest.
1. Cars must be able to move down the provided ramp with a raw egg as a passenger and
withstand multiple crashes with a solid barrier at the end of the ramp.
2. Teams may use only cardboard for the structure of their car. Wheels and axels must
consist of container lids and wooden rods as explained in class. No other wheels and
axels will be permitted.
3. Once the car is built, additional items may be used inside the car. Items must be
approved by Mrs. Smith before incorporated into the car.
4. Each team’s car must meet these dimensions to race.
Height - 12 cm high maximum, no minimum
Length – 25 cm long maximum, no minimum
Width - 11 cm wide maximum, no minimum
Weight – no minimum nor maximum
# Wheels – minimum of 3
5. Each team will need to keep their supplies & race car in the provided container before &
after class. You are responsible for the safety of the supplies and your car.
6. On race day, cars will be released down the ramp by a member of your design team. It’s
key to practice. Ramps may be used for test trials during class time leading up to race
day during class, study halls, or homeroom time. If needed, Mrs. Smith reserves the
right to limit number of test trails per group.
7. On race day, the egg must be “healthy” & unbroken after impact.
8. Race day eggs will be inspected by Mrs. Smith before and after the crash and must
remain unbroken. Mrs. Smith has all final decisions! Eggs that survive the initial impact but roll out of the device and break or can’t be removed from the device are eliminated and will receive a zero on the safety section of the rubric. Teams that break their egg by accident or carelessness are eliminated and will receive a zero for the safety section of the rubric. Again, Mrs. Smith has final decisions!

FINAL PROJECT: - 50 points
1. Photo – 10 points 1. Take a photo of your car and print it out. 2. Attach it to cardboard, poster board, or construction paper. 3. Neatly place the name of your race car above the photo.
2. Planning of ACE paragraph in science journal – 10 points 1. Use planning skills you’ve learned in your English classes to plan out your ACE
paragraph responding to this prompt: The designing, building, and racing of your Egg-cellent Race Car required the
understanding and application of many scientific principles regarding force and motion.
Choose 3 of these principles and clearly describe how your understanding of each of these scientific concepts played a major role in your race car.
Use your Alphabox list as a resource as you begin organizing your thoughts. 2. Be sure to accurately and descriptively provide evidence to explain your
understanding and application of the scientific principles involved in the forces and
motion of your car. To support your understanding and application of your 3 chosen scientific
principles, use your science notes, the videos watched, diagrams reviewed,
class discussions, and/or independent research as evidence. o In your “cite”, include
definitions of each principle
examples of each principle
o In your “explain”, include
how you applied this science concept to build the car
examples on the race car of where each principle is
used
3. ACE paragraph final copy - 20 points 1. Type your final ACE paragraph in 12 font, double-spaced, Times New Roman font. 2. See the attached rubric. 3. Print out your paragraph.
4. Photo and ACE paragraph combined together for display – 10 points 1. Neatly attach your typed paragraph below your photo on poster board. 2. Neatly place your name on the front side of your display underneath your paragraph.
