Declaring a resource that is not recognized

Question

Hello All,

I am new to Terraform and have written the following resource in my main.tf file: 

module "aws_s3_bucket" {

bucket = "s3bucketcopeland"

source = "terraform-aws-modules/s3-bucket/aws"

}

From my understanding this should setup the s3 bucket, however I keep getting this error message: 

│ A managed resource "aws_s3_bucket" "s3bucketcopeland" has not been declared in the root module.

Any ideas where I may be going wrong?
