Composition of He Lin's popular science practice activities

Yesterday we went to the popular science practice base in Zhuxi Park.

When I first entered the gate of Zhuxi Park, I saw a hollow stone tablet. In the exposed hole of the stone tablet, there is a bamboo forest with green bamboo leaves. Walking along the winding path, there is a bunch of flowers on the left. The flower is white, and the edge of the flower is red, like a girl's long skirt. There is a pool next to the flowers. It's full of water lilies, so cute.

The instructor took us to a yard. There are many rooms in the yard, and each room has an interesting little experiment waiting for you ... Two of the most impressive activities are Ling Bo Walking and Lighter Collection.

Let's talk about Ling Bo's stroll. The instructor took us to a room with no lights or windows.

"Students, do you want to learn to float on the water with flying skills?" The teacher smiled mysteriously and said.

"think!" The students said in unison. I observed the difference between this room and other rooms while answering. "Strange, this room is no different from other rooms. Does the teacher want to trick us into walking on the floor? " I am full of doubts. Then, the teacher asked us to take a walk in the pond in the middle of the room. "Hey? And walking on the floor? Can I really float on the water? " I'm even more confused. Look behind me, sparkling, like the feeling of rain dripping on the water when it rains. I firmly believe that I will "float lightly on the water".

"Classmates, congratulations! Please look at your head. What is it? " The teacher smiled.

"projector?" "sensor?" "There seems to be a mirror." ..... The students are talking.

"I know!" Xu Senrong shouted excitedly, "The small fish pond above us reflected on the projector through the mirror, and the projector reflected the image to the ground and turned it into a fish pond. The signal that we step on the ground is transmitted to the sensor, and the sensor transmits the signal to the projector, which becomes a ripple. Am I right? " The teacher gave him a thumbs-up sign.

Lighters are also very interesting. They have various shapes, including bicycles, drinking fountains, rockets and pesticides ... If the teacher didn't tell us it was a lighter, we really wouldn't have seen it.

This activity is really interesting. I wonder what surprises the next popular science practice will give us?
