The email is great!
However, mention that you would like an appointment to meet with the principal and any other teacher who might be interested. Then follow up with a phone call in a day or two to set up an appointment.

As for your brother, it would be wonderful if mom and dad would spring for a Mindstorm kit for home and let your brother play with it. Don't teach him, but rather help him if he asks or program the bot yourself and maybe show him how you did something clever. In other words, the goal is not to teach him programming, but to stimulate his curiosity.

And, as others have pointed out,take him to a competition. The FLL is the "real deal"; the only FIRST (unlike FRC, FTC) where all the teams have mastered autonomous programming.

Best of luck!
