EGG DROP
OBJECT: To provide a container which will protect a raw egg when dropped from an altitude to a hard surface like cement flooring.
TEAM: Maximum of two (2) members. At least one (1) team member must be assigned to drop the container.
APPARATUS:
1. The members of the team must construct (at home, etc.) the container prior to the contest.
2. Each container must meet the following specifications:
a. Maximum mass - 30 g.
b. Body size - the container must fit inside a rectangular box 10 cm x 10 cm x 20 cm.
c. Parachute - 20 cm x 20 cm x 40 cm.
3. A variety of materials may be used: paper, cardboard, foam materials (like Styrofoam), rubber bands, feathers, string, glue, etc.
4. Fins and other aerodynamics paraphernalia may be added. They should not exceed the 10 cm x 10 cm x 20 cm limit before the container is dropped but must fit within a 20 cm x 20 cm x 40 cm box in flight.
5. At no time during the fall may any part of the container have any material exceed the maximum dimensions as outlined above. This allows for parachutes and other wind dragging elements, provided they remain within 20 cm x 20 cm x 40 cm dimensions throughout the fall.
6. All containers must be checked in during registration. No further work will be permitted after the entry has been checked in.
COMPETITION:
1. A grade A medium chicken egg will be supplied for each entry. Eggs will be furnished at the physics Olympics site. Contestants must be able to secure their eggs in the containers within 10 minutes immediately prior to the drop.
2. The container will be dropped from successive heights until a breakage occurs. The minimum height a container must survive is one meter.
3. Between drops, repairs may be made provided no additional material is added to the container.
4. The mass of the entry
container will be determined before the first drop.
SCORING:
1. In determining the winners, the following formula will be used:
Score
= (100 x H) / M1.6
where H = greatest height in meters, attained without breaking.
M = mass, in grams, of the empty container. The exponent places a high premium on economy of design.
The entry obtaining the highest
score will get the
2. In the event that the eggs
still remain unbroken at the maximum height available in the area, the entries
will be judged according to their masses.
The lightest will be declared winner and if a tie occurs, both will be
declared winners. (Example: If there are
two First Placers, they will each get 20 points, but the next in rank will get
only the points for the Third Placer).
OBJECT: To construct a free-standing tower of maximum height using a single sheet of bond paper (long size).
TEAM: Maximum of two (2) in a team.
No one other than those actually constructing towers will be permitted
in the room during the contest.
MATERIALS: (To be supplied by the contestant).
1. Ruler
2. One small roll of cellophane tape
3. Pair of scissors and blades
RULES:
1. Each team will be given one sheet of paper at the start of the contest. Only one entry will be allowed for judging.
2. The sheet of paper may be cut into pieces and reassembled as desired. Parts may be rolled, folded, or slit.
3. Cellophane tape may be used to fasten the parts of the tower together. It may not be used to attach the tower to the floor or any other object.
4. No other glues or tapes may be used. The paper may not be soaked, painted or chemically treated to add rigidity.
5. A tower shall be declared free-standing if it remains self-supporting for more than 10 seconds.
6. Height is determined by measuring the perpendicular distance from the highest point of the tower to the floor.
7. Each team must complete the construction of each tower within an hour.
8. The three tallest towers will
be declared First, Second
LARGE BARGE
OBJECT: To construct a barge which can support the greatest load without sinking.
TEAM: Maximum of two (2) members.
RULES:
1. Each team will be given a piece of aluminum foil not more than 30 cm in length.
2. Each team will construct within 15 minutes a barge out of the given material without using tape, glue, staples or any other material.
3. The barge must be loaded while floating on a basin of water.
4. Only dry loads should be used. If any water leaks into the barge during the loading process, the barge will be considered sinking. Thus damp or wet cargo must be unloaded, the barge dried and reloaded. Only two reloading will be allowed.
5. Each team will be allowed one repair of its construction after thorough drying.
6. The barge that supports the heaviest dry load will be considered the winner and others judged accordingly.
7. Loads will consist of standard weights. The dry load just before the barge sinks will be the one recorded. If the load gets wet, the test must be repeated. Only 2 repetitions will be allowed. Consistently wet cargo will be a cause for disqualification.
PAPER AIRPLANE
OBJECT: To construct an airplane of largest range and time of flight.
TEAM: Maximum of two (2) members per team.
A. The competition
1. Two separate rounds will be run, one for distance and one for time of flight. The same plane must be used for each round. Each team will have only one airplane.
2. In each case, the following rules and requirements pertain:
a. Teams will design and construct their own airplanes prior to the Olympics.
b. Preferably, the competition will take place in an open air field or gymnasium where wind velocity is negligible and insignificant and launches will be executed by the competitor horizontally from a standing position, and at shoulder level.
c. No dimension (length, width, or height) of the aircraft should exceed 50 cm.
d. Stepping beyond the assigned marker will be a fault.
e. A second fault will disqualify the contestant.
f. The mass of the braces, struts, weight added, glue, clips, etc. shall not exceed twice the mass of the paper in the aircraft. If there is a question of this upon initial inspection, the plane will be analyzed after the competition, but before finalization of places.
g. Each team will be allowed two launches in each round with the best score for the set being retained for purposes of the competition.
h. Each team will compete in each part of the competition.
i. No practice flights will be allowed in the vicinity of the launching area during the duration of the contest.
B. Scoring
Distance Round
1. Horizontal distance from the point in the ground directly below the launch point to the position of first impact with the ground will be measured.
2. Impact with any object prior to hitting the ground will allow a repetition of a launch.
3. The greatest distance achieved will be awarded 20 points with all other scores scaled proportionately to distance achieved to the nearest tenth of a point.
Time-of-Flight Round
1. In this part of the contest, the airplane may be launched at any angle.
2. Time from the flight of the airplane until first impact with the floor will be measured by two or three timers.
3. The average time of the timers to the nearest tenth of a second will be recorded.
4. Greatest duration will be assigned 20 points with all other scores scaled proportionately to the nearest tenth of a point.
Total Score:
The total score is composed of the two (2) scores thus obtained. The highest scoring team will be awarded 20 points towards the total competition. The second is 15 points and the third is 10 points.
In the event two teams have the same total score, both will be made to play the game again and the final winners determined from the game.
EGG TRANSPORT
OBJECT: To build a vehicle powered by a rubber band or rubber
strip, which can carry an egg to the greatest horizontal distance.
TEAM: Maximum of two (2) members per team.
RULES:
1. The contestants are to design and construct their own “cart” or vehicle prior to the contest. The cart or vehicle can be made of any inanimate material (commercial or scratch-built) like an empty spool. This is to be checked in. No further work will be allowed after checking in during registration.
2. The rubber band or strip as a source of energy must be a part of the vehicle. Catapults or other launching devices attached are not allowed. (No other sources of energy are allowed.)
3. Up to 6 rubber bands or strips may be used. A strip formed into a loop will be counted as two. The width of the band/strip should not exceed 5 mm.
4. The maximum mass of the vehicle or device should not exceed 100 grams.
5. The egg may be rolled or carried by the vehicle.
6. The egg should remain unbroken or undamaged during the roll or transport. A starting line will be marked on the floor.
7. The vehicle must move on a lane 50 cm wide. If the vehicle strikes the boundary side or line in the course of the roll/transport, that point will be marked as the end of the roll.
8. If the egg separates from the vehicle, the point at which the egg separates will be marked as the end of the roll/transport.
9. Winners will be determined on the basis of horizontal distance moved (perpendicular to the starting line) during the roll/transport.
10. Each team will be allowed two trials, with the greater distance retained for purposes of the competition.
