Our predictions on how our eco-column would survive over the 3 week period

At the beginning of the 3 week period

We predicted that our Terra zone would not survive an that all the plant and animals in that zone would die due to it not having a sufficient supply of water. Our decomposition zone had more than enough substances to decompose and we predicted that it should survive very well over the 3 week period. All of the plants and animals in our aqua zone had died very quickly due to the lack of oxygen in the aqua zone. This means that there was only water left in the aqua zone which we presumed would survive the holiday apart from slightly overflowing.

At the end of the 3 week period

All of our predictions were more or less very accurate and consistent, this could be due to some factors which were easy to calculate affecting our eco-column in the way which we predicted. Except not all the plants in our terra zone died, only the wheat grass which we presume is very water dependent  The Aqua zone stayed more or less the same apart from becoming extremely full and the decomposition zone was able to decompose everything which we had left for it at the beginning of the holidays.
