Your communication plan will need to show how you will remain safe while doing your communication projects. It may require that you have an adult designated by the school with you when you communicate with adults outside the school. Your school will have a policy about how students can use telephones and emails.
Your school will have policies about how you can communicate with people outside your school. As part of your plan you will need to show how you will remain within school policy. If you come up with a very original idea, your school may not have a policy. You may need to help them make up a policy that shows how you will stay safe.
