1, I drew an accurate parabola, did the experiment of magnesium rod burning in the air, opened the deepest reflection surface of the mouse, and tried to convert heat with my left hand holding my right hand. Finally, I found the answer that you rejected me from the periodic table. I am carbon dioxide, which doused the original flame.

2. Under the dark green light, the bubbles bubble slowly in the test bottle, and the experimenter keeps cutting the human body and putting it into the container.

In order to prove that the spider's hearing is on the foot, the expert did an experiment. He first put a spider on the experimental platform, and then shouted at the spider, and the spider scared away! Then I grabbed the spider back, cut off all its feet and yelled at the spider. The spider really didn't move! So I published a paper that proved that spiders' hearing is on their feet.

4. Those days when running under dazzling white light were soaked in test tubes like specimens. As false as life. High school is my glass test tube, and the formalin soaked in specimens is the liquid that seeps out after years have passed.

5, ah! The pear tree is in blossom! The snow-white petals caught my attention. I ran over and stared at the pear flower. It has at least five petals. If I don't look carefully, I won't see its pistil. She seems to be playing hide-and-seek with us.

6. I opened the stamens around me and saw a shower nozzle, which was pistil. I touched the small nozzle and felt sticky. My mother told me gently: because the powder pollinated by bees should be on the pistil, if there is no mucus, the powder will be blown away by the wind.
