One possible version:
Dear Mr Bruce,
I’m delighted you have accepted our invitation to give a lecture about Astronomy: the science of the stars at our school on 15th, May.
As we agreed, you’ll be speaking on the topic from 8 am to 11 am. There will be extra minutes for questions.
Would you please tell me what you’ll need then? If you could let me know your specific requirements by 10th, May, I’ll have plenty of time to make sure that the school hall provides you with what you need
Thank you again for agreeing to speak. I look forward to hearing from you.
