F4 and F5 Tornadoes

I like the weather so I wanted to do something with it. I chose F4 and F5 tornadoes because I like big, strong tornadoes.

To complete my project I got on the Internet, went to a site called MetaFind, and typed in Oklahoma tornadoes. I printed out all of them and made a graph. I concluded that 25 tornadoes occurred between 4:00 and 6:00 p.m. and 24 occurred between 6:00 and 8:00 p.m. I learned that there are a lot of F4 and F5 tornadoes in Oklahoma.

I would like to do another project because I like weather, especially tornadoes.
