I. Purpose of the event
Apply the learned scientific knowledge to solving practical problems and cultivate innovative ability in the process of analyzing and solving problems.
Second, the activity creativity
"Shenzhou VII" manned space flight was a complete success, and China's space industry continued to strive for newer breakthroughs and more brilliant achievements after making major breakthroughs. This competition is mainly to simulate the landing of an airplane. Inspire students to pack parachutes and other high-altitude objects and articles, cultivate students' ability to participate in scientific and technological practice, and enhance their sense of innovation. The entries require reasonable design, fixed-point landing, smooth landing and novel ideas.
Three. background material
The activity of eggs hitting the earth was first seen in the youth science and technology activities organized by the Youth Department of the British Association for the Advancement of Science in the 1980s. Later, it was introduced to Hong Kong by teachers of the Hong Kong Association for Science and Mathematics Education and carried out among primary and secondary school students. By the early 1990s, the china welfare institute Children's Palace in Shanghai was further improved, and it was organized among Shanghai teenagers and was welcomed by them. Later, the teachers of Guangzhou Physics Teaching and Research Association organized teenagers to hold an "Eggs on the Earth" competition in Guangzhou, which attracted many young lovers to participate. At present, the world's strongest record is held by Fang Ming, a professor at the Hong Kong University of Science and Technology. He designed a funnel-shaped buffer device. The part of the egg in contact with the ground is made of elastic material (similar to the exhaust plastic corrugated pipe in the kitchen). The whole equipment is only 1.2g, which is unparalleled at present.
Fourth, the active object.
Students in grades 3-6.
Verb (abbreviation for verb) Activity time and place
1. Activity time: June12-June 23rd.
On June 12, the publicity campaign was launched, and each class selected 1-3 outstanding works to participate in the competition. Submit the application form to the guidance office before June 16, and the competition will be officially held on June 23rd.
2. Location: the third floor of the primary school teaching building, with concrete floor downstairs.
Organization of intransitive verb competition
1. design requirements: throw an ordinary raw egg on the concrete floor from the third floor. On the premise that the eggshell is not broken, the lighter the quality of the whole work, the more accurate the landing, the higher the score, and the winner with the highest score. Competition eggs cannot be treated by physical or chemical methods. Eggs and their protective devices are designed and prepared by themselves, and no part of the protective device is allowed to be placed in the landing site or falling route.
2. Delivery requirements: The contestants will be in place on time according to the specified time and place, and those who are late for 10 minutes will be disqualified. Each work can only be put into production once.
3. Fixed-point landing: After receiving the instruction at the designated place of the competition, the contestants will immediately drop their works (organization+eggs). After the egg landed and stopped, the referee weighed the unbroken outer packaging of the work (everything except the egg).
4. Scoring standard: On the premise that the eggs are not broken, the lightest weight (except eggs), accurate landing and novel and beautiful appearance are the high scores.
Seven. Award settings
1, the competition will be graded according to the final score from high to low, with the top six: first prize 1; Two second prizes; Three third prizes.
2. If there are other unfinished matters, the referee will discuss and decide separately.
