How do primary school students write research reports

The research report can be written like this: first ask questions. I saw the harm of drinking on TV and thought that I was an out-and-out "music fan". Now my teeth have some symptoms. I want to investigate the harm of primary school students drinking coke.

Ask questions first. I like drinking. First, investigate whether cola and cola are harmful to us.

Second, the survey method:

1. Learn about the dangers of drinking cola for primary and middle school students from the website.

2. Learn what it's like for primary and middle school students to drink Coke through the news broadcast on TV.

3. Investigation and data collation: information channels, involved aspects, specific content, through network investigation, the harm of primary school students drinking cola, and the harm of children drinking cola.

Cola contains caffeine, and 1 bottle of 340g cola beverage contains 50-80mg caffeine. Someone has done experiments. Adults who take caffeine more than 1 g at a time can cause central nervous system excitement, accelerated breathing, tachycardia, insomnia, dizziness and tinnitus.

Even if the dosage of 1 time is less than 1 g, poisoning symptoms such as nausea, vomiting, dizziness, palpitation and precordial pain will occur due to the stimulation of gastric mucosa.

How do primary school students feel about drinking coke now?

Accelerated breathing, tachycardia, insomnia, dizziness, tinnitus. There will be poisoning symptoms such as nausea, vomiting, dizziness, palpitation and precordial pain. A study shows that soda can accelerate bone loss, especially for girls who love to drink cola, and the probability of fracture is five times that of those who don't drink soda!

Four. The conclusions are as follows:

Drinking coke will corrode teeth and be harmful to children. Cola contains caffeine, and 1 bottle of 340g cola beverage contains 50-80mg caffeine.

Someone has done experiments. Adults who take caffeine more than 1 g at a time can cause central nervous system excitement, accelerated breathing, tachycardia, insomnia, dizziness and tinnitus. Even if the dosage of 1 time is less than 1 g, poisoning symptoms such as nausea, vomiting, dizziness, palpitation and precordial pain will occur due to the stimulation of gastric mucosa.

Children are more sensitive to caffeine than adults, so don't give them cola drinks. Young girls beware of osteoporosis. A study shows that soda can accelerate bone loss, especially for girls who love to drink cola, and the probability of fracture is five times that of those who don't drink soda!

Experts pointed out that phosphoric acid in cola may be the cause of easy fracture. Phosphoric acid is harmful to bones because it has adverse effects on calcium metabolism and bones. Therefore, we try not to touch cola, because we are very sensitive to cola.
