Hey Mr. Burk,
School email is down, and I have not been able to contact you. I don't think I will be able to make it to school tomorrow, considering I still don't feel well. I know the class will have the whole time to work on the project and I was wondering if Melissa should try to build the projectile or get the written work done. Melissa's internet is down, so we have been communicating by phone. Please email me at emily.fuqua18@gmail.com with the best option for tomorrow. Thanks. Emily
