Our biology teacher has a birthday. It's her birthday, she's 50 years old. Please help me choose a gift for my class

Biology teacher can get a new microscope! And to make her even more satisfied, you should give her a cube postcard, which will show photos with her favorite students. You will find examples of a cube postcard here https://boomf.com/collections/50th-birthday-cards. Your teacher will be happy with such a gift, because it was chosen with soul.
