What else is due?

In addistion to the other assignments listed on the previous post we now have a couple of new things due:
1. Description of pH experiment
2. Description of field trip to BKFarmyards to learn about hoop houses.
What are they? What are the pros and cons of them? Can CAS have one? Would you build one?
3. Final reflection: What did you like about the class? What are you still interested to learn about or be involved in? What do you recommend be different for the next class?
4. Your part of the chapter of the Garbage to Gold (Trash/compost) book.
