Last Wednesday,Mr Chan took his class to the Space Museum.First,the children watched a movie about space travel.They saw how the space shuttle (航天飞船) took off in space and later landed on earth again.It was very exciting and the children felt that they were travelling in space themselves!
After the movie,Mr Chan took them to see some models of rockets (火箭) and the space shuttle.The models looked very real,but they were smaller.The children also saw some moon stones.Two Americans landed (着陆) on the moon in 1969.They put an American flag (旗) there.Then they brought some stones back to the earth.
Before the children left,they watched a video show about people living and working in a spacelab (太空实验室).The spacelab was very big.There were kitchens,bathrooms,bedrooms and a big workshop for people to work in.The people could stay in the spacelab for months.
