Describe how far off you were and hypothesize why
What observations were of the greatest interest or concern to you this week
Our compost chamber had started to biodegrade the banana peel. There wasn't any real concerns.
What adjustments did you make to address your concerns
What do you predict you will observe next week because of these adjustments
We believe that the banana peel will be more degraded and we expect to have our animal by then as well.
Any real world application to what you saw this week?
