Science 10 November 20th
Several weeks ago, our science teacher Mr.Zhai asked us to work on a science fair project.Firstly, I should find a partner,I found Christie Cai because she is one of my best friends.Secondly, we should decide what our project will be about, with several minutes discussion we foud out that our parents always told us that if we put the phone beside your heads when you are going to sleep, the radiation from the phone will affect your sleep quality.But we think it’s not scientific, so we started designing the experiments. The required materials are iwatches and our phones.For the first five days, we put the phones away from our pillows, we all went for sleep at 10pm.On tomorrow morning, we woke up at 6am.The iwatches are connected to your phones so it can tell you how long did you shallow sleep and deep sleep last for.After the first five days, we put our phone near our pillows.With the effort we take, we got some datas. After we analyzed the data, we found out that the difference between two situation is just a few minutes.The results show that may be our parents’hypothesis is not true for every one and we can put the phone beside our pillows as well.
