In conclusion, phones and other technology should be banned from school because they negatively affect students in school and aren't necessary items for them to have. It has been shown that students spend to much time attached to their phone, which brings around problems such as lack of sleep, eye problems, and lower grades. Some people may say that they want their kids to have phones in order to stay in contact with them or keep them safe.

Banning, or at least taking away students' phones during school days will increase productivity and decrease distractions.
