Dear Ibrahim

I am sending you a link with an exceptionally well-made chemistry virtual simulation lab which is perfect for high school students.

I hope that suits your needs,

Best regards

P.S. May appreciations to the creators of the content!

Dear Antonis, thank you so much for your answer. Best whises.

I think virtual chemistry will help motivated high school chemistry students, but from my relatively brief high school level teaching experience, there is no substitute for real world spectacular chemistry demonstrations, and experiments to stir the interest of all students.

I have a nice AP level thermochemistry experiment detailed at the link below.
