  1. EggXpress(Grades 7 & 8, 11 & 12) Prepared by Adam Lazaro

  2. Purpose Students design and construct a container (of a specific size) that holds eggs and keeps them from breaking after falling from a great height. 1-2 students per team

  3. Overview Container should be designed to maximize BOTH the number of total eggs in package, and percentage of eggs which survive the impact. 1-2 students per team

  4. MATERIALS • Large, Fresh, Raw, White Eggs • Only Paper tape or Masking tape allowed LEGAL

  5. ILLEGAL • Treated, boiled, or rotten eggs • Small or medium eggs • Duct tape, “Scotch-type” tape • Parachutes or Aerodynamic devices • No splattering (messy) materials, e.g. • Peanut butter • Jell-o • Liquids • Powder

  6. Rules • Container must fit “EASILY” through a 14” diameter hoop. • Label containers with: • Names • School • MESA Center (UCSB) • # of eggs in container • Lab Report, legible

  7. Scoring .25 deduction per egg in container 4 points for LAB REPORT Equation for scoring Drop Score = SE-(.25xTE) SE=number of Surviving Eggs TE= Total eggs in Package

  8. Scoring Discussion Question ? Do you think it is smart to have a lot of eggs in your container? (Discuss with team members before going to next slide) Remember how scoring is applied - (.25 deduction per egg in container)

  9. Example #1 of Scoring Let’s say… your team engineered a container holding 10 Eggs • So, according to the equation: • Your team’s TE (Total Eggs in the Package)= 10 • Now, your Package is dropped, and your team finds out that only 6 eggs survived. • So, according to the equation: • Your team’s SE (Surviving Eggs)= 6 * Before moving to next slide, calculate your Drop Score so that you are sure that you have an understanding of how the scoring is determined.

  10. Answer #1 Plugging the values into the equation gives us our final drop score. Drop Score = 6 - (.25 x 10=2.5)=3.5 If you TURN in a completed LAB REPORT, you get 4 more points! So, now, your total score for this drop & report would be = 7.5 HINT: Remember to write a Lab Report. It really helps out your score!!!

  11. Example #2 of Scoring Let’s say that your team engineers a container that holds 32Eggs… • So, according to the equation: • Your team’s TE (Total Eggs in the Package)= 32 Now your Package is dropped and your team finds out that only 18 eggs survived… • So, according to the equation: • Your team’s SE (Surviving Eggs)= 18 Before moving to next slide, calculate your Drop score so that you are sure that you have an understanding of the how the scoring is done.

  12. Answer Plugging the values into the equation gives us our final drop score. Drop Score= 18-(.25x32)=10 If you TURN in a completed LAB REPORT you get 4 more points. So the total score would be= 14 REMEMBER TO WRITE THE LAB REPORTS It really helps out your score!!!

  13. Conclusion To make sure that you fully understand the scoring process, discuss other possible outcomes. There are many strategies for the Packaged Egg Drop. The fun part is figuring out which approach your team wants to take, and what the outcomes and risks are. You could either cram a bunch of eggs into a package and hope for the best… Or you could safely package fewer eggs to insure a reasonable score. • It is always a good idea to test your Packaged Egg Drop design before the actual competition. • You can test a smaller number of eggs, or a small model of your package, first. Make design or packaging material changes, according to your test results, to insure your best results.
