How accurate was (were) your prediction(s) from last week?
We were accurate from last week when we said our banana peel would be more decomposed and we do have our snail.

Describe how far off you were and hypothesize why.
We weren't off.

What observations were of the greatest interest or concern to you this week?
The banana peel was decomposed and moldy.

What adjustments did you make to address your concerns?
There wasn't any adjustments to be made.

What do you predict you will observe next week because of these adjustments?
N/A

Any real world application to what you saw this week?
The decomposition of the banana, and the browning of the plant.

How accurate was (were) your prediction(s) from last week?
There wasn't any qualitative or quantitative data from last week.

Describe how far off you were and hypothesize why.
N/A

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?
N/A

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?
No.
