I wholeheartedly agree with Xidelt. None of those activities sound fun. They all are borderline hazing. Pennsylvania's anti-hazing laws can be found easily online. If there is a question in your mind that an activity could be mistaken for hazing, then when you ask yourself "Should we do this?" the answer should be no.
Your new member period is a time to learn about the organization, the values and histories that you will now represent. It is also a time to learn about the sisters and yourself. It should be a time of growth as a sister and as a human.
Some activities I did as a new member last semester included:
1. New member retreat: all the new members and our new member educator met at our NME's apartment. She bought us pizza and pop. We sat in her living room, and we played Just Dance and did a few ice breakers. Then she let us get to know each other a bit. This was nice because there were four girls who got COB bids that I did not know at all! When there was an hour left in the retreat, she started teaching us some chants and we picked one we wanted to show the actives at our sisterhood retreat. We picked one we had never done before and taught the actives. We also watched youtube videos of our schools greek week, to give us an idea of what it was all about. I really enjoyed the new member retreat. I left knowing my new member class much better.
2. New Member meetings were made fun. We learned our histories and traditions, but we also learned about the sisters. The week we preffed for big/little, our NME gave us a slideshow showing each sister, with her major, interests, hometown, etc.
3. Owl Pals: Every week between Bid day and big/little, we were given a different owl pal. These girls wrote us notes each day and left them in our mailboxes, with clues as to who she was. At the end of the week, they left us a small gift and revealed who they were. The notes sometimes included information about them, but also could just be a "Dear XYZ, I hope you are having a great day! Study hard, you're pretty, etc" It was sweet, and I felt so spoiled!!
