How to make a good investigation report on green plants
About the plant investigation report, just like keeping a diary, it is enough to record it every day.

For example: garlic.

Today 12 March, I took a piece of garlic and peeled it gently. Then I found an empty mineral water bottle, cut off the big piece on it, leaving only the bottom part; Then pour in half the water, and then put the garlic in. Know what I'm doing? Yes, I'm kind of garlic.

Today, in March 13, garlic was found to be a little green. Garlic is going to sprout! I quickly changed a bottle of water and found that the roots had grown. I took a ruler and measured it. The root is only a little long, about1mm.

Today, March 15, I came to see my garlic. Ah, the garlic bud was a little hazy the day before yesterday, so I couldn't see it clearly. Now there are two green shoots, about 7 mm long. Afraid of insufficient nutrition in the water, I changed the water again.

Today 17 March, I found that the green bud of garlic is very long, about 1 cm long, and the other one grows faster, with a total length of1.3cm. When changing water, it was found that the garlic root was 4 mm long and * * * was 5 mm long.

Today is March 19, I change water for garlic. It was found that the bottom of garlic was soaked in water, and a thin layer of white skin was tightly attached to garlic, which was fleshy, while the upper part of garlic was still so white without being soaked in water. But I found the white skin protruding a little. I guess it may be sprouting again.

Today, on March 22nd, I found a small green bud with a length of about 3 mm on the protruding point of white skin. I was so happy that I quickly changed the water for fear that the nutrients in the water could not satisfy the growth of garlic. I also found that two small green shoots grew 1 cm, the tallest 2.5 cm and the shortest 2 cm. Garlic roots have also become spiral.

Today, on March 23, I found that the green shoots of garlic grew by 3 mm, the highest was 2.9 cm, the middle was 2.3 cm and the shortest was 6 mm. I can't measure garlic roots with a ruler, because the roots are twisted. I estimate that they are 6 mm long.

Today, on March 24th, I found a small green bud less than 1mm among the three green buds, so I quickly changed the water. I took a ruler, the longest of which is 3 cm long. I thought: How did this garlic sprout suddenly grow so fast? The day is getting longer. I don't know what's going on.

Today, March 25, I found that the tallest garlic bud grew 5 mm, the little green bud that just emerged grew 2 mm, and the two in the middle grew 3 mm. Finally, I changed the water.
