There will be a Mission Eggcellence Competition and an Automotive Engineering Competition for grades K-2, 3-5, 6-8, and 9-12. (You may have your students compete in the appropriate competitions. Example: If you teach 3rd and 6th grades, you may enter your 3rd graders in the 3-5 grade competitions and your 6th graders in the 6-8 grade competitions.)

How many participants:

  1. Two teams – one for the Mission Eggcellence competition (1 to 3 students) and one for the Automotive Engineering competition (1 to 3 students). You CANNOT have more than 3 students in a competition. You CAN only have ONE Mission Eggcellence competition team and ONE Automotive Engineering competition team.
  2. Each team may consist of 1 to 3 students. So you may bring one student for both competitions or up to 3 students per competition.
  3. I need the names of the participants. Report by January 10.
  4. Your team needs a name – example the Bulldogs or the Eggheads.

What to bring:

  1. Your bumper already assembled
  2. Your Balsa wood car already assembled
  3. Glue gun and glue
  4. Waiver forms already signed by parents (Form is attached.)
  5. Student reflection forms

Teachers will remain in their seats during the competition. (You may come down near the front to take pictures when your team is doing their trial run, but you are NOT allowed near the student tables.)

Food and gum will NOT be allowed.

Only student participants will be allowed to repair their cars or repair bumpers. (Teachers may not help.) Replacement of existing parts is allowed. New parts cannot be added. Parts cannot be removed. The mass of the car or bumper will be measured again after the adjustments.

Summary of Rules (Download the complete set of rules at the top)

Mission Eggcellence car (bumper)

  1. Wooden bumper made from 1/4” x 2” x 4” poplar. Can be purchased at Lowe’s 1/4” x 2” x 4’ poplar strips. Cut these to 4” lengths for one bumper. Bumper is 4 inches wide. 4 INCHES WIDE
  2. Students will bring a bumper design for competition which must attach to the car via 3/4” by 3” Velcro strip. Use the loopy part of the Velcro, not the fuzzy part. The cars which I will furnish during the competition will have the fuzzy part!
  3. Students can replace one item for each trial. Bumper mass will be measured after replacement. The new mass cannot increase or decrease by more than 3 grams. You may not add new items or delete any items. You will be given 5 minutes to do the replacement.
  4. The bumper cannot slow down the car (bumper cannot touch the ramp, wheels, or ramp rails).
  5. Balloons, balls, or inflated objects are NOT allowed. Parachutes or “free fall” devices which retard the cars acceleration will NOT be allowed.
  6. Spongy, rubber, springs, or air filled material (bubble wrap, etc.) cannot be more than 3/4” thick total. This means if you use a spring and a piece of rubber, the total thickness of both items together can only be 3 / 4 “ thick. Other items (NOT spongy, rubber, or air filled material) may be used with this. Styrofoam is not spongy, rubber, or air filled. The entire bumper cannot be more than 1 ” thick including the wood.
  7. Only students will be allowed to secure the bumper to car and secure the egg in car. (Teachers will NOT be allowed to help.)
  8. Students will remove their egg after each run and give it to the judge for examination.

Automotive Engineering Car

  1. Students will bring their Automotive Engineering car. The car can ONLY be made from
    1. K-5 - K’nex pieces. Wheel must be at least 2” diameter K’nex wheels plus the rubber tire. Possible tire – K’nex # 90979 and black tire 91976. The competition is on the design of the chassis.
    2. 6-12 - Balsa Wood and glue. No bumper. The wheels must be regular CDs – diameter of 4 3/4”. The competition is on the design of the chassis.

  6. Car must roll freely, no binding, no friction drag. Only the wheels of the car can touch the ramp. If the car does not roll freely, the team will be allowed 5 minutes to correct the problem. The car’s mass will be measured again. If the car does not roll freely on the second try, the team will be disqualified.
