Large class teaching plan "Observing why ants move"

nature is a wonderful world, and the weather on the earth is changeable. Our clever ancestors, after five thousand years of observation and accumulation, finally compiled thousands of meteorological proverbs. Once, I saw such a proverb in a book about meteorology-"it will rain if ants move." I'm skeptical. Is it certain that it will rain when ants are busy moving? So I have a strong curiosity to test this proverb.

One afternoon in summer, I was enjoying the cool under a big tree when I happened to find a group of black ants moving. They are all in a hurry, some with ivory ant eggs, some with beige ant pupae, some with old ants, injured ants, and some with all kinds of food ... I suddenly thought of that proverb, so I settled down to observe and verify it. I looked up at the high blue sky, and now it is clear in Wan Li. The sun is burning, spreading light and heat to the earth without mercy, and there are several white clouds floating on the horizon. Curiosity drove me to observe along the line of ants, and I found that ants were moving higher.

after a few hours, the blue sky began to clear up and turn cloudy. After a while, it was overcast with clouds, lightning and thunder, and soon it began to rain cats and dogs. Now, I am speechless. I secretly praised you, little ants, you are really a barometer that can breathe!

After this incident, I learned that these proverbs are based on science. I am proud that we have such ancestors.
