Sitting in the garden, Newton watched an apple fall from a tree. He began to wonder if the same force that pulled the apple down also kept the moon circling the earth. Newton believed it did. He called it “gravity(重力)”. This st...
It was a large device that looked like a can surrounded the pilot's head. Astronauts in the American space agency (NASA) flew the first American space flights in the early 1960s. The clothing was similar to that invented by Wiley Post.Today, astronauts wear very different protective clothing...
On Earth, gravity(重力) helps a plant's stems and roots to find " up" and"down". However, in the space station, there was almost no gravity.Dr. Williams suggested a solution: give the plants more light, as plants also use sunlight to find their way.And it worked. When the plants ...
