Tea that is 70 degrees Celcius or more can increase the risk of a person getting oesophgeal squamous cell carcinoma, or OSCC. Scientists did their research in Iran because they drink a large amount of tea there. They studied 300 people with OSCC who drang approximatly a litre of hot tea per day and compared them to 571 healthy people who also drank about 1 litre of hot tea per day. Through these studies, they found that people who drank hot tea were twice as vulnerable to OSCC as people who drank warm tea, and that people who drank really hot tea were eight times more likely to develop OSCC.
The independant variable in this experiment is the temperature of the tea. The dependant variable is the amount of people who developed OSCC. There were 300 trials for people with OSCC and 571 trials for people without OSCC.
I thought this was a pretty good experiment because they had alot of trials. Altough they had alot of trials, i would have done the same amount of trials for OSCC people and healthy people. To follow this experiment, they could have tried other hot drinks such as hot chocoloate or coffee to see if they also caused OSCC.

You did a great job of explaining the experiment and stating your ideas towards it. They should have also tried using people who didnt drink tea.
