Eggs falling from a high place, must they be broken for this answer the little brain melons burned

Katie Wang and her work

If an egg falls from a high place, it will be broken?

When Teacher Hong of the Sha'er Primary Moral Education Office threw out this question, the students began to talk about it. Some say yes with certainty, and some confidently say no.

Curious, everyone rubbed their hands and went home to experiment. After a few days of trying, I don't know how many eggs were broken, and the students had the answer.

On April 12, each class of the first and second grades selected 5 students to participate in the competition. The contestants brought their own carefully protected eggs, some with balloons, some with sticks, some with foam...

Everyone stood together by the fourth-floor window, holding their breath, gently releasing their devices, and their little hearts fluttered and fluttered with the eggs, "Don't break it." When the egg landed, the students quickly ran downstairs.

"Wow, it's not broken." There were children cheering. "Oh, how did I break it?" I'm not going to give up, go back and continue to modify my device and fight again next year. Some children said optimistically.

At the end of the competition, 52 players successfully challenged, and the eggs landed without breaking.

Katie Wang's egg is wrapped in a round thick plastic foam, which is the work of the 102nd class that won the first prize. She explains her work to everyone, "I wrap the eggs tightly with more shock-absorbing materials. Considering the overall weight, the lighter the better, so as to reduce the impact of falling to the ground, while making a sphere, the surrounding force after landing is uniform, can better ensure that the egg is intact. ”

Zhang Zhibo's eggs are packed in a thick plastic foam box, which is also equipped with a parachute, which turns out that he used the principle of parachute to increase the resistance of the air and reduce the speed of the egg falling.

"Whether successful or not, the child's brain and hands-on ability have been improved. More importantly, it stimulates children's desire to explore science. Teacher Hong concluded. Reporter Ruan Feixia
