Fun things to do in Salt Lake City..?

My family and I are going to spend two days in Salt Lake City in mid-April. I have two teenagers ages 14 and 17. We are not very interested in seeing a lot of Mormon attractions, because we aren't Mormons, but one or two LDS things would be ok. We are thinking of going to a Salt Lake Bees game and a Utah Jazz game. What else would you recommend for some fun things to do in and around SLC for a family with teenagers?
